    Hidden species diversity and mito-nuclear discordance within the Mediterranean cone snail, Lautoconus ventricosus2023Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 186, s. 107838-107838, artikel-id 107838Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Mediterranean cone snail, Lautoconus ventricosus, is currently considered a single species inhabiting the whole Mediterranean basin and the adjacent Atlantic coasts. Yet, no population genetic study has assessed its taxonomic status. Here, we collected 245 individuals from 75 localities throughout the Mediterranean Sea and used cox1 barcodes, complete mitochondrial genomes, and genome skims to test whether L. ventricosus represents a complex of cryptic species. The maximum likelihood phylogeny based on complete mitochondrial genomes recovered six main clades (hereby named blue, brown, green, orange, red, and violet) with sufficient sequence divergence to be considered putative species. On the other hand, phylogenomic analyses based on 437 nuclear genes only recovered four out of the six clades: blue and orange clades were thoroughly mixed and the brown one was not recovered. This mito-nuclear discordance revealed instances of incomplete lineage sorting and introgression, and may have caused important differences in the dating of main cladogenetic events. Species delimitation tests proposed the existence of at least three species: green, violet, and red + blue + orange (i.e., cyan). Green plus cyan (with sympatric distributions) and violet, had West and East Mediterranean distributions, respectively, mostly separated by the Siculo-Tunisian biogeographical barrier. Morphometric analyses of the shell using species hypotheses as factor and shell length as covariate showed that the discrimination power of the studied parameters was only 70.2%, reinforcing the cryptic nature of the uncovered species, and the importance of integrative taxonomic approaches considering morphology, ecology, biogeography, and mitochondrial and nuclear population genetic variation.

    Morphology of the larvae of Rhantaticus congestus (Klug, 1833) and phylogenetic comparison with other known Aciliini (Coleoptera: Dytiscidae: Dytiscinae)2023Ingår i: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 5380, nr 3, s. 247-264Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We describe the second- and third instar larvae of the diving beetle Rhantaticus congestus (Klug, 1833), including detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, terminal abdominal segment and urogomphi in order to discover useful characters for distinguishing Rhantaticus Sharp, 1882 larvae from those of other known Aciliini (Coleoptera: Dytiscidae: Dytiscinae). A parsimony analysis based on 94 larval characteristics of nine Aciliini species in five genera (Acilius Leach, 1817, Graphoderus Dejean, 1833, Rhantaticus, Sandracottus Sharp, 1882, Thermonectus Dejean, 1833) was conducted using the program TNT. Rhantaticus shares with all these genera several larval character states which support its inclusion in the Aciliini. Whereas Rhantaticus larva stands out from other known genera by several unique character states, our parsimony analysis did not recover any clear phylogenetic position of this genus within the Aciliini.

    Larval morphology of the Madagascan endemic diving beetle genus Hovahydrus Biström, 1982 (Coleoptera: Dytiscidae) and phylogenetic comparison with other known Hyphydrini2022Ingår i: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 5219, nr 3, s. 227-246Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We describe for the first time the instar III larva of the diving beetle genus Hovahydrus Biström, 1982, based on H. praetextus (Guignot, 1951) and a new species yet to be described (identified here as Hovahydrus sp. near H. minutissimus (Régimbart, 1903)). We include detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphi in order to discover useful characters for distinguishing Hovahydrus larvae from those of other known Hyphydrini (Coleoptera: Dytiscidae, Hydroporinae). A provisional parsimony analysis based on larval characteristics of 11 Hyphydrini species in eight genera was conducted using the program TNT. Larval morphology supports a close relationship between Hovahydrus, Hyphydrus Illiger, 1802, and the endemic South Africa genera Andex Sharp, 1882, Coelhydrus Sharp, 1882, Darwinhydrus Sharp, 1882 and Primospes Sharp, 1882.

    Abstract [en]

    Open-habitat chats (genera Myrmecocichla, Cercomela, Oenanthe and relative) are a morphologically and ecologically cohesive group of genera with unclear phylogenetic relationships. They are distributed mostly in open, arid and/or rocky habitats of Africa and Eurasia. Here, we present the most comprehensive molecular phylogenetic analysis of this group to date, with a complete taxon sampling at the species level. The analysis, based on a multilocus dataset including three mitochondrial and three nuclear loci, allows us to elucidate the phylogenetic relationships and test the traditional generic limits. All genera are non-monophyletic, suggesting extensive convergence on similar plumage patterns in unrelated species. While the colour pattern appear to be a poor predictor of the phylogenetic relationships, some of the ecological and behavioural traits agree relatively well with the major clades. Following our results, we also propose a revised generic classification for the whole group.

    Comprehensive molecular phylogeny of the grassbirds and allies (Locustellidae) reveals extensive non-monophyly of traditional genera, and a proposal for a new classification2018Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 127, s. 367-375Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The widespread Old World avian family Locustellidae (‘grassbirds and allies’) comprises 62 extant species in 11 genera. In the present study, we used one mitochondrial and, for most species, four nuclear loci to infer the phylogeny of this family. We analysed 59 species, including the five previously unsampled genera plus two genera that had not before been analysed in a densely sampled dataset. This study revealed extensive disagreement with current taxonomy; the genera Bradypterus, Locustella, Megalurus, Megalurulus and Schoenicola were all found to be non-monophyletic. Non-monophyly was particularly pronounced for Megalurus, which was widely scattered across the tree. Three of the five monotypic genera (Amphilais, Buettikoferella and Malia) were nested within other genera; one monotypic genus (Chaetornis) formed a clade with one of the two species of Schoenicola; whereas the position of the fifth monotypic genus (Elaphrornis) was unresolved. Robsonius was confirmed as sister to the other genera. We propose a phylogenetically informed revision of genus-level taxonomy, including one new generic name. Finally, we highlight several non-monophyletic species complexes and deep intra-species divergences that point to conflict in taxonomy and suggest an underestimation of current species diversity in this group.

    Phylogeny and classification of the avian superfamily Sylvioidea.2006Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 38, nr 2, s. 381-97Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Sylvioidea is one of the three superfamilies recognized within the largest avian radiation, the parvorder Passerida. In the present study, which is the first taxon-dense analysis of the Sylvioidea based on sequence data (nuclear myoglobin intron II and mitochondrial cytochrome b gene), we investigate the interrelationships among the four "sylvioid" clades found by previous workers, as well as the relationships within the largest of these clades. The nuclear and mitochondrial loci estimate basically the same phylogeny, with minor differences in resolution. The trees based on myoglobin and the combined data identify a strongly supported clade that includes the taxa previously allocated to Sylvioidea, except for Sitta (nuthatches), Certhia (treecreepers), Parus (tits), Remiz (penduline tits), Troglodytes and Campylorhynchus (wrens), Polioptila (gnatcatchers), and Regulus (crests/kinglets); this clade also comprises larks, which have previously been placed in the superfamily Passeroidea. We refer to this clade as Sylvioidea. This clade is further divided into 10 main, well-supported clades, which we suggest form the basis for a revised classification.

    Multilocus analysis of a taxonomically densely sampled dataset reveal extensive non-monophyly in the avian family Locustellidae.2011Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 58, nr 3, s. 513-26Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The phylogeny of most of the species in the avian passerine family Locustellidae is inferred using a Bayesian species tree approach (Bayesian Estimation of Species Trees, BEST), as well as a traditional Bayesian gene tree method (MrBayes), based on a dataset comprising one mitochondrial and four nuclear loci. The trees inferred by the different methods agree fairly well in topology, although in a few cases there are marked differences. Some of these discrepancies might be due to convergence problems for BEST (despite up to 1×10(9) iterations). The phylogeny strongly disagrees with the current taxonomy at the generic level, and we propose a revised classification that recognizes four instead of seven genera. These results emphasize the well known but still often neglected problem of basing classifications on non-cladistic evaluations of morphological characters. An analysis of an extended mitochondrial dataset with multiple individuals from most species, including many subspecies, suggest that several taxa presently treated as subspecies or as monotypic species as well as a few taxa recognized as separate species are in need of further taxonomic work.

    Non-monophyly and intricate morphological evolution within the avian family Cettiidae revealed by multilocus analysis of a taxonomically densely sampled dataset.2011Ingår i: BMC Evolutionary Biology, E-ISSN 1471-2148, Vol. 11, s. 352-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: The avian family Cettiidae, including the genera Cettia, Urosphena, Tesia, Abroscopus and Tickellia and Orthotomus cucullatus, has recently been proposed based on analysis of a small number of loci and species. The close relationship of most of these taxa was unexpected, and called for a comprehensive study based on multiple loci and dense taxon sampling. In the present study, we infer the relationships of all except one of the species in this family using one mitochondrial and three nuclear loci. We use traditional gene tree methods (Bayesian inference, maximum likelihood bootstrapping, parsimony bootstrapping), as well as a recently developed Bayesian species tree approach (*BEAST) that accounts for lineage sorting processes that might produce discordance between gene trees. We also analyse mitochondrial DNA for a larger sample, comprising multiple individuals and a large number of subspecies of polytypic species.

    RESULTS: There are many topological incongruences among the single-locus trees, although none of these is strongly supported. The multi-locus tree inferred using concatenated sequences and the species tree agree well with each other, and are overall well resolved and well supported by the data. The main discrepancy between these trees concerns the most basal split. Both methods infer the genus Cettia to be highly non-monophyletic, as it is scattered across the entire family tree. Deep intraspecific divergences are revealed, and one or two species and one subspecies are inferred to be non-monophyletic (differences between methods).

    CONCLUSIONS: The molecular phylogeny presented here is strongly inconsistent with the traditional, morphology-based classification. The remarkably high degree of non-monophyly in the genus Cettia is likely to be one of the most extraordinary examples of misconceived relationships in an avian genus. The phylogeny suggests instances of parallel evolution, as well as highly unequal rates of morphological divergence in different lineages. This complex morphological evolution apparently misled earlier taxonomists. These results underscore the well-known but still often neglected problem of basing classifications on overall morphological similarity. Based on the molecular data, a revised taxonomy is proposed. Although the traditional and species tree methods inferred much the same tree in the present study, the assumption by species tree methods that all species are monophyletic is a limitation in these methods, as some currently recognized species might have more complex histories.

    Dramatic niche shifts and morphological change in two insular bird species2015Ingår i: Royal Society Open Science, ISSN 2054-5703, Vol. 2, artikel-id 140364Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Colonizations of islands are often associated with rapid morphological divergence. We present two previously unrecognized cases of dramatic morphological change and niche shifts in connection with colonization of tropical forest-covered islands. These evolutionary changes have concealed the fact that the passerine birds madanga, Madanga ruficollis, from Buru, Indonesia, and São Tomé shorttail, Amaurocichla bocagii, from São Tomé, Gulf of Guinea, are forest-adapted members of the family Motacillidae (pipits and wagtails). We show that Madanga has diverged mainly in plumage, which may be the result of selection for improved camouflage in its new arboreal niche, while selection pressures for other morphological changes have probably been weak owing to preadaptations for the novel niche. By contrast, we suggest that Amaurocichla's niche change has led to divergence in both structure and plumage.

    Patterns of diversification amongst tropical regions compared: a case study in Sapotaceae.2014Ingår i: Frontiers in Genetics, E-ISSN 1664-8021, Vol. 5, nr 362Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Species diversity is unequally distributed across the globe,with the greatest concentration occurring in the tropics. Even within the tropics, there are significant differences in the numbers of taxa found in each continental region. Manilkara is a pantropical genus of trees in the Sapotaceae comprising c.78 species. Its distribution allows for biogeographic investigation and testing of whether rates of diversification differ amongst tropical regions. The age and geographical origin of Manilkara are inferred to determine whether Gondwanan break-up, boreotropical migration or long distance dispersal have shaped its current disjunct distribution. Diversification rates through time are also analyzed to determine whether the timing and tempo of speciation on each continent coincides with geoclimatic events. Bayesian analyses of nuclear (ITS) and plastid (rpl32-trnL,rps16-trnK,and trnS-trnFM) sequences were used to reconstruct a species level phylogeny of Manilkara and related genera in the tribe Mimusopeae. Analyses of the nuclear data using a fossil-calibrated relaxed molecular clock indicate that Manilkara evolved 32–29 million years ago (Mya) in Africa. Lineages within the genus dispersed to the Neotropics 26–18 Mya and to Asia 28–15 Mya. Higher speciation rates are found in the Neotropical Manilkara clade than in either African or Asian clades. Dating of regional diversification correlates with known palaeoclimatic events. In South America, the divergence between Atlantic coastal forest and Amazonian clades coincides with the formation of drier Cerrado and Caatinga habitats between them. In Africa diversification coincides with Tertiary cycles of aridification an duplif tof the east African plateaux. In South east Asia dispersal may have been limited by the relatively recent emergence of land in New Guinea and islands further east c.10 Mya.

    Un nouveau nom dans la tribu des Vanguerieae (Rubiaceae) de Madagascar2020Ingår i: Candollea, ISSN 0373-2967, E-ISSN 2235-3658, Vol. 75, nr 1, s. 71-73Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A variety of the Malagasy genus Canthium Lam. (Rubiaceae, Vanguerieae), Canthium perrieri var. louvelii Cavaco, is transferred to the genus Pyrostria Comm. ex Juss. because, like the typical variety already transferred in this genus, it shares its distinctive characters (inflorescences or solitary flowers involucrate). This taxon is further raised to species level, as it is morphologically distinct from Pyrostria perrieri (Cavaco) Razafim. et al. We provide the necessary new replacement name: Pyrostria orientalis A. Atalahy, Rakotanas. & Razafim., since the epithet louvelii is already occupied in Pyrostria.

    Molecular systematics and evolution of the Synallaxis ruficapilla complex (Aves: Furnariidae) in the Atlantic Forest.2013Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 67, nr 1, s. 86-94Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Neotropical Synallaxis ruficapilla complex is endemic to the Atlantic Forest and is comprised of three species: S. ruficapilla, S. whitneyi, and S. infuscata. This group is closely related to the Synallaxis moesta complex that occurs in the Andes, Tepuis, and Guianan shield. Here we used mitochondrial and nuclear gene sequences to infer the phylogeny and the time of diversification of the S. ruficapilla and S. moesta complexes. We also included samples of an undescribed population of Synallaxis that resembles other populations of the S. ruficapilla complex. Our results showed that different geographical lineages within the S. ruficapilla complex are reciprocally monophyletic, but the northern form (S. infuscata) grouped with an Andean taxon. This suggests that at least two lineages of this group independently colonized the Atlantic Forest. Specimens of the undescribed population formed a monophyletic clade with deep divergence. Estimated diversification dates were within the late Pliocene to Pleistocene (2.75-0.16 million of years ago). This suggests that at this time there was a higher connectivity between habitats in the rugged landscapes of the circum-Amazonian bioregions. The observed Pleistocene diversification within the Atlantic Forest is congruent in space and time with studies of other co-distributed organisms, and may be associated with climate changes and tectonic activity during this period.

    Phylogeny and historical biogeography of gnateaters (Passeriformes, Conopophagidae) in the South America forests.2014Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 79, s. 422-432Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We inferred the phylogenetic relationships, divergence time and biogeography of Conopophagidae (gnateaters) based on sequence data of mitochondrial genes (ND2, ND3 and cytb) and nuclear introns (TGFB2 and G3PDH) from 45 tissue samples (43 Conopophaga and 2 Pittasoma) representing all currently recognized species of the family and the majority of subspecies. Phylogenetic relationships were estimated by maximum likelihood and Bayesian inference. Divergence time estimates were obtained based on a Bayesian relaxed clock model. These chronograms were used to calculate diversification rates and reconstruct ancestral areas of the genus Conopophaga. The phylogenetic analyses support the reciprocal monophyly of the two genera, Conopophaga and Pittasoma. All species were monophyletic with the exception of C. lineata, as C. lineata cearae did not cluster with the other two C. lineata subspecies. Divergence time estimates for Conopophagidae suggested that diversification took place during the Neogene, and that the diversification rate within Conopophaga clade was highest in the late Miocene, followed by a slower diversification rate, suggesting a diversity-dependent pattern. Our analyses of the diversification of family Conopophagidae provided a scenario for evolution in Terra Firme forest across tropical South America. The spatio-temporal pattern suggests that Conopophaga originated in the Brazilian Shield and that a complex sequence of events possibly related to the Andean uplift and infilling of former sedimentation basins and erosion cycles shaped the current distribution and diversity of this genus.

    Estimating the Phanerozoic history of the Ascomycota lineages: Combining fossil and molecular data2014Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, nr 78, s. 386-398Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The phylum Ascomycota is by far the largest group in the fungal kingdom. Ecologically important mutualisticassociations such as mycorrhizae and lichens have evolved in this group, which are regarded as keyinnovations that supported the evolution of land plants. Only a few attempts have been made to date theorigin of Ascomycota lineages by using molecular clock methods, which is primarily due to the lack ofsatisfactory fossil calibration data. For this reason we have evaluated all of the oldest available ascomycetefossils from amber (Albian to Miocene) and chert (Devonian and Maastrichtian). The fossils representfive major ascomycete classes (Coniocybomycetes, Dothideomycetes, Eurotiomycetes, Laboulbeniomycetes,and Lecanoromycetes). We have assembled a multi-gene data set (18SrDNA, 28SrDNA, RPB1 andRPB2) from a total of 145 taxa representing most groups of the Ascomycota and utilized fossil calibrationpoints solely from within the ascomycetes to estimate divergence times of Ascomycota lineages with aBayesian approach. Our results suggest an initial diversification of the Pezizomycotina in the Ordovician,followed by repeated splits of lineages throughout the Phanerozoic, and indicate that this continuousdiversification was unaffected by mass extinctions. We suggest that the ecological diversity within eachlineage ensured that at least some taxa of each group were able to survive global crises and rapidlyrecovered.

    Species diversification in the Mediterranean genus Chiliadenus (Inuleae-Asteraceae)2018Ingår i: Plant Systematics and Evolution, ISSN 0378-2697, E-ISSN 1615-6110, Vol. 304, nr 7, s. 853-860Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Chiliadenus is a small genus in the Inuleae (Asteraceae), consisting of ten species with allopatric distributions along the southern edge of the Mediterranean Sea. The different species have restricted areas of distribution, with only one being more widely distributed. The first molecular phylogenetic study of the genus with complete sampling, as well as a biogeographic analysis of the origin and biogeographic patterns leading to the current diversity of Chiliadenus is presented. Results confirm Chiliadenus as monophyletic and placed as sister to Dittrichia. The ancestor of Chiliadenus is dated to have diverged from that of Dittrichia around 5.45 Ma ago, coinciding with the Messinian salinity crisis, whereas the Chiliadenus crown group is dated to 2.29 Ma, around 3 million years later. Ancestral area reconstructions show the crown group to likely have originated in the area around Morocco and northwestern Algeria, which is also the area where the early divergences have occurred. Chiliadenus has then later diverged and dispersed over the Mediterranean to its current distribution. The evolution of the Chiliadenus crown group coincides with the onset of the Mediterranean climate, and its evolution may be connected to the subsequent climatic changes.

    The Malagasy enigmatic genus Apodocephala (Asteraceae), a new member of the tribe Athroismeae2021Ingår i: Willdenowia, ISSN 0511-9618, E-ISSN 1868-6397, Vol. 51, nr 2, s. 221-230Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Apodocephala is a small genus of nine species of shrubs and trees endemic to Madagascar and currently classified in the tribe Astereae (Asteraceae). However, its present tribal position has been questioned, as it lacks some of the salient morphological features of that tribe. This study includes for the first time DNA sequences from Apodocephala (two species including the type of the generic name) to test its phylogenetic position. Phylogenetic analyses based on sequence data from nuclear ribosomal (ETS and ITS) and plastid (ndhF and trnL–trnF) DNA regions, using Bayesian inference and maximum parsimony methods, strongly reject the placement of Apodocephala in the Astereae. Our results, instead, support its position as sister to the Malagasy monospecific genus Lowryanthus within the tribe Athroismeae. Morphological comparison of these sister genera reveal similarities in cypsela morphology, and the inclusion of Apodocephala in the subtribe Lowryanthinae is proposed here. The tribe Athroismeae is now represented by ten genera (Anisochaeta, Anisopappus, Apodocephala, Artemisiopsis, Athroisma, Blepharispermum, Centipeda, Leucoblepharis, Lowryanthus and Symphyllocarpus), six of which occur in Madagascar. The Malagasy Athroismeae occur in all Malagasy terrestrial ecosystems (rainforests, deciduous dry forests, thicket spiny forests and savannas) and are likely the result of multiple independent colonization events mostly from mainland Africa.

    Phylogeny of the Athroismeae (Asteraceae), with a new circumscription of the tribe2017Ingår i: Taxon, ISSN 0040-0262, E-ISSN 1996-8175, Vol. 66, nr 2, s. 408-420Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Athroismeae is a small tribe of the Asteraceae-Asteroideae, the members of which show considerable variation in morphology. A molecular phylogenetic study of the tribe is presented for the first time, based on plastid (ndhF, trnH-psbA, trnL-trnF) and nuclear data (ETS, ITS). The phylogenetic relationships between the different genera within Athroismeae are discussed, and in addition, three unispecific genera: Anisochaeta, Artemisiopsis and Symphyllocarpus as well as Duhaldea (Inula) stuhlmannii, all earlier placed in other tribes, are here shown to belong within Athroismeae. Symphyllocarpus is sister to Centipeda and the earlier Symphyllocarpinae includes Centipedinae in synonymy. Furthermore, Cardosoa and Philyrophyllum are found to be integrated within Anisopappus and their generic status cannot be maintained. An outline of an amended circumscription of the Athroismeae is presented, with three new combinations and a description of the new subtribe Lowryanthinae.

    Evolution and diversification related to rainfall regimes: diversification patterns in the South African genus Metalasia (Asteraceae-Gnaphalieae).2015Ingår i: Journal of Biogeography, ISSN 0305-0270, E-ISSN 1365-2699, Vol. 42, nr 1, s. 121-131Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim. The Cape region is known for its exceptional species richness, although much remains unknown regarding the appearance of the modern Cape flora. One explanation is that floral diversification was influenced by the establishment of winter rainfall/summer arid conditions hypothesized to have occurred towards the end of the Miocene. We studied the evolution and diversification of the plant genus Metalasia (Asteraceae–Gnaphalieae), with the aim of testing whether radiation patterns may have been influenced by the climatic changes.

    Location. South Africa, with emphasis on the south-west.

    Methods. The radiation of Metalasia was investigated using two approaches: a species diffusion approach, which estimated the ancestral areas by means of a relaxed random walk while sampling from extant distributions; and a discrete approach, in which distributions were defined according to the phytogeographical centres of the Cape region. Secondarily derived clock rates from an earlier Gnaphalieae study were used for calibration purposes.

    Results. Our analyses date Metalasia to approximately 6.9 Ma, after the Miocene–Pliocene boundary and the establishment of the winter rainfall/summer arid conditions. Metalasia consists of two sister clades: Clade A and Clade B. Clade B, which is endemic to the winter rainfall area, is estimated to have diversified c. 6.4 Ma, whereas Clade A, with a main distribution in the all-year rainfall area, is considerably younger, with a crown group age estimated to 3.3 Ma. Diversification rates suggest an early rapid speciation, with rates decreasing through time both for Metalasia and for clades A and B separately. Ancestral area estimations show a possible scenario for the radiation of Metalasia to its current diversity and distribution, with no conflict between results inferred from diffusion or discrete methods.

    Main conclusions. The diversification of Metalasia is estimated to have begun after the establishment of the winter rainfall/summer arid conditions, consistent with its radiation having been influenced by changes in the climatic regime.

    Phylogeny of Anisopappus with species circumscriptions revisited (Asteraceae: Athroismeae)2021Ingår i: Taxon, ISSN 0040-0262, E-ISSN 1996-8175, Vol. 70, nr 2, s. 351-364Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Anisopappus (Asteraceae: Athroismeae) is a genus with its main distribution in Africa (one species also in Asia), currently considered to include around 21 species. A molecular phylogenetic study of Anisopappus is presented for the first time, based on plastid (ndhF, trnL-trnF, trnQ-rps16) and nuclear (ETS, ITS) data. Anisopappus is confirmed to be monophyletic, and species interrelationships are resolved. The results differ from earlier treatments based on morphology, and the phylogenetic analyses reveal a need for changes in species circumscriptions as compared to those of the most recent treatment. Consequently, many taxa currently treated as synonyms are here shown to represent separate species indicating that the genus includes well over 40 species. Distribution patterns now emerge where several clades are found to consist of species restricted to a particular geographical region. The Anisopappus of Madagascar, many of which were earlier placed in synonymy with species found on the African continent, are here shown to be endemic, and the results reveal a need for further studies of that group.

    Distoleon tetragrammicus (Fabricius, 1798) ny myrlejonslända för Norden och en illustrerad nyckel till arterna (Neuroptera: Myrmeleontidae).2022Ingår i: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 143, nr 1-2, s. 25-37Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We report the first finding of the antlion Distoleon tetragrammicus (Fabricius, 1798) fromSweden. Several adults of the species have been collected or photographed on the island ofGotland in the Baltic Sea, between 2017 and 2021. The first finding is from Tofta skjutfält,a sandy military training ground vegetated with pines and mixed forests on the west coastof Gotland. Based on multi-year observations at the same locality as well as video recordingof an egglaying female it is clearly a resident population, even though larvae are yet to bedocumented. Distoleon tetragrammicus is not previously known from any of the Nordic orBaltic countries. The species is common in southern Europe with a wide distribution acrosswest palearctic and becomes rarer towards central Europe. The closest known locality isan outpost population on the Hel peninsula on the Polish Baltic coast which we speculateis the most probable source, 240km south of Gotland across the Baltic sea. Previously butthree species of antlions were known from the Nordic-Baltic countries, all belonging to thetypical pitfall trap-building tribe Myrmeleontini and subfamily Myrmeleontinae: Myrmeleonformicarius (Linnaeus, 1767), Myrmeleon bore (Tjeder, 1941) and Euroleon nostras (Geoffroyin Fourcroy, 1785). Distoleon tetragrammicus belongs to subfamily Nemoleontinae (tribeNemoleontini) with larvae being ambush predators without the behaviour of building pitfalltraps. We provide an identification key, as well as studio and field photographs of all fourNordic species. The quality and conservation value of Tofta military training ground localityfor insects is discussed with reference to other rare species.

    Entomologmötet på Gotland 2017: temaexkursion med fokus på vattenlevande skalbaggar, skinnbaggar och trollsländor i Äskåkersvät.2017Ingår i: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 139, nr 1, s. 39-49Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The yearly Swedish entomology meeting 2017 was organized by the local entomology

    society of Gotland, on the northern part of the Baltic island Gotland near Bunge, 4-6 August.

    One thematic excursion was focused on aquatic insects, especiallly aquatic beetles,

    bugs and dragonflies. A shallow pond, Äskåkersvät, with Characeae in an open grazed

    landscape with high natural values was studied. Äskåkersvät lies just adjacent to the larger

    area around lake Bästeträsk which is the focus of a pilot study evaluating its potential as

    a future national park. The pilot study is undertaken by Gotland County Administrative

    Board, the Swedish Environmental Protection Agency, Region Gotland and the Swedish

    Agency for Marine and Water Management. Here we give an annotated report of the 103

    species found: 69 species of water beetles (out of which 34 were Dytiscidae), 20 species

    of aquatic or semiaquatic bugs (out of which 10 were Corixidae), and 14 species of dragonflies.

    These include Hydrophilus piceus and H. aterrimus redlisted in Sweden (both as

    NT), and Dytiscus latissimus, globally redlisted (VU). We also noted the noble crayfish,

    Astacus astacus (redlisted as CR in Sweden) and the European medicinal leech Hirudo

    medicinalis (redlisted as NT globally). The blue emperor dragonfly (Anax imperator) was

    noted, a species first recorded from Gotland in 2002 and we present a graph on its increase

    and spreading on the island since. The number of species found in spite of a relatively

    modest collecting effort at a suboptimal time when many species may be in pupal stage out

    of water as witnessed by many teneral individuals, indicates a species rich locality with

    high natural value. The stoneworts (Characeae) vegetation certainly contributes to this, for

    instance vouched for by the occurrence of specialists as Haliplus confinis and H. obliquus

    whose larvae feed on stoneworts.

    Åkerjordfly, Agrotis exclamationis, identifierad som värdart för svävflugan Villa hottentotta med hjälp av DNA streckkodning (Diptera: Bombyliidae).2015Ingår i: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 136, nr 4, s. 121-130Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this study we identify Agrotis exclamationis (Linnaeus, 1758) as a host species for the bee y Villa hottentotta (Linnaeus, 1758) in Sweden. Host use and speci city for bee y species are generally very poorly known, why the hatching of a bee y of the genus Villa from an unknown Noctuid pupa caught our attention. The parasitized Noctuid pupa was found in a garden in Staffanstorp, Skåne (Sweden), in May 2015 and kept in a jar to hatch. The bee y hatched in June leaving two empty exuviae in the jar. DNA was extracted sepa- rately from both excuviae to identify the y and the host using DNA Barcoding. A 600+ bp long sequence of the gene Cytochrome oxidase subunit 1 was sequenced for both samples and queried against the reference library BOLD (www.boldsystems.org). The Noctuid host pupa was unambiguously identi ed as the common Noctuid species Agrotis exclamationis. The sequence was identical to the most common haplotype over much of Europe. The bee y pupa was identi ed as Villa hottentotta, the most common Villa species in Sweden. This added a new Noctuid species to the list of known hosts for V. hottentotta which also includes several other Noctuid genera as well as a Geometrid moth. Belonging to the sand chamber group of bee ies where the female scatter the eggs on the ground while hovering, the active host-seeking rst instar planidium larvae bene ts from having a wide host range to potentially encounter in the substrate zone.

    A new species of Bidessus from Anjozorobe-Angavo and a review of Malagasy Bidessus (Coleoptera, Dytiscidae)2020Ingår i: European journal of taxonomy, E-ISSN 2118-9773, Vol. 720, nr 1, s. 1-18Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We review the species of Bidessus of Madagascar and describe Bidessus anjozorobe sp. nov. from material collected in Anjozorobe forest. Anjozorobe is part of the Anjozorobe-Angavo Protected Area, which is an important corridor of transition forest between typical eastern humid forests and the residual sub-humid forest of the Central Highlands. Bidessus longistriga Régimbart, 1895 and Bidessus perexiguus Kolbe, 1883 are widespread but endemic low-altitude species on Madagascar. Bidessus nesioticus Guignot, 1956 is an alpine species described from near the peak of the Ankaratra mountain massifs at 2500 m a.s.l. We recollected the species for the first time since its description, in Ankaratra and in a new area above 2000 m a.s.l. in the Andringitra mountain further south. Bidessus cf. nero Gschwendtner, 1933 is tentatively recorded for Madagascar for the first time but further studies are needed to test the status of mainland and insular populations. Bidessus apicidens Biström & Sanfilippo, 1986 has not been recollected on Madagascar since 1970. All species are endemic to Madagascar except potentially Bidessus cf. ceratus and Bidessus cf. nero described from Uganda and the Democratic Republic of the Congo, respectively. The older records of the two non-endemic species Bidessus complicatus Sharp, 1904 and Bidessus ovoideus Régimbart, 1895 on Madagascar could not be verified.

    Species delimitation of the Hyphydrus ovatus complex in western Palaearctic with an update of species distributions (Coleoptera, Dytiscidae)2017Ingår i: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, Vol. 678, s. 73-96Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The species status of Hyphydrus anatolicus Guignot, 1957 and H. sanctus Sharp, 1882, previously often confused with the widespread H. ovatus (Linnaeus, 1760), are tested with molecular and morphological characters. Cytochrome c oxidase subunit 1 (CO1) was sequenced for 32 specimens of all three species. Gene-trees were inferred with parsimony, time-free bayesian and strict clock bayesian analyses. The GMYC model was used to estimate species limits. All three species were reciprocally monophyletic with CO1 and highly supported. The GMYC species delimitation analysis unequivocally delimited the three species with no other than the three species solution included in the confidence interval. A likelihood ratio test rejected the one-species null model. Important morphological characters distinguishing the species are provided and illustrated. New distributional data are given for the following species: Hyphydrus anatolicus from Slovakia and Ukraine, and H. aubei Ganglbauer, 1891, and H. sanctus from Turkey.

    Two new species of the megadiverse lentic diving-beetle genus Hydrovatus (Coleoptera, Dytiscidae) described from NE Thailand.2016Ingår i: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, nr 632, s. 57-66Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Here we describe two new Hydrovatus species (Coleoptera: Dytiscidae: Hydroporinae: Hydrovatini) from the province of Khon Kaen, Isan region in NE Thailand. Hydrovatus is the third most species rich genus of diving beetles (Dytiscidae). It occurs on all continents except Antarctica and now numbers 210 currently recognized species. Both new species, Hydrovatus diversipunctatussp. n. and Hydrovatus globosussp. n., were collected at lights and are only known from the type locality "Khon Kaen" (a city and province). Diagnoses based on morphology for the separation from closely related species are given together with illustrations of male genitalia and habitus photos. We provide a determination key to Old World species of the pustulatus species group and to Oriental species of the oblongipennis species group.

    Abstract [en]

    The African species of the genus Laccophilus Leach, 1815, are revised, on the basis of study of adult specimens. In all, 105 species are now recognized. A phenetic character-analysis was undertaken, which resulted in a split of the genus into 17 species groups. Diagnoses and a description of each species are given together with keys for identification of species groups and species. We also provide habitus photos, illustration of male genitalia and distribution maps for all species. New species are described as follows: Laccophilus grossus sp. n. (Angola, Namibia), Laccophilus rocchii sp. n. (Tanzania, Namibia, Botswana, Mozambique), Laccophilus ferrugo sp. n. (Mozambique), Laccophilus furthi sp. n. (Madagascar), Laccophilus isamberti sp. n.

    Repeatedly Northwards and Upwards: Southern African Grasslands Fuel the Colonization of the African Sky Islands in Helichrysum (Compositae)2023Ingår i: Plants, Vol. 12, nr 2213, s. 1-24Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Afromontane and Afroalpine areas constitute some of the main biodiversity hotspots of Africa. They are particularly rich in plant endemics, but the biogeographic origins and evolutionary processes leading to this outstanding diversity are poorly understood. We performed phylogenomic and biogeographic analyses of one of the most species-rich plant genera in these mountains, Helichrysum (Compositae-Gnaphalieae). Most previous studies have focused on Afroalpine elements of Eurasian origin, and the southern African origin of Helichrysum provides an interesting counterexample. We obtained a comprehensive nuclear dataset from 304 species ( 50% of the genus) using target-enrichment with the Compositae1061 probe set. Summary-coalescent and concatenation approaches combined with paralog recovery yielded congruent, well-resolved phylogenies. Ancestral range estimations revealed that Helichrysum originated in arid southern Africa, whereas the southern African grasslands were the source of most lineages that dispersed within and outside Africa. Colonization of the tropical Afromontane and Afroalpine areas occurred repeatedly throughout the Miocene–Pliocene. This timing coincides with mountain uplift and the onset of glacial cycles, which together may have facilitated both speciation and intermountain gene flow, contributing to the evolution of the Afroalpine flora.
