    Abstract [en]

    Four known and one new species of Onchium are described from bottom sediments collected in Skagerrak off the west coast of Sweden. The following known species are redescribed: Onchium ocellatum Cobb, 1920, O. metocellatum Wieser, 1956, O. parocellatum (Allgén, 1940) and O. robustum Gerlach, 1965. Onchium longispiculum sp. n. is characterised by the 1.34–1.77 mm long body, anterior body end without cephalic capsule, anteriormost somatic sensilla located posterior to onchiostyle base, ocelli absent, excretory pore located at basis of lips, onchiostyle uniformly cylindrical, alveolar sup- plements indistinct, tubular supplements absent, spicules arcuate and 44–65 μm long. The new species has a unique set of characters (absence of developed ocelli and very long somewhat asymmetrical spicules) separating it from all other known species of the genus Onchium. The following nomenclatorial changes are proposed: O. conicaudatum (Allgén, 1935) is considered a junior synonym of O. metocellatum; O. conicaudatum apud Wieser, 1951 is considered a synonym of O. minutum Kito, 1981. The diagnosis of the genus Onchium is emended and a tabular compendium and dichotomous iden- tification key to species of the genus Onchium are provided.

    The nomenclatural status of new nematode nomina proposed in 1993 in the doctoral thesis of Christian Bussau, entitled Taxonomische und ökologische Untersuchungen an Nematoden des Peru-Beckens (Nematoda)2020Ingår i: Bionomina: International Journal of Biological Nomenclature and Terminology, ISSN 1179-7649, E-ISSN 1179-7657, Vol. 19, s. 86-99Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In his doctoral thesis, Christian Bussau published 110 new nematode nomina, including 97 nomina of new species, 11 of new genera and two of new subfamilies. The nomenclatural availability of these nomina has not been generally accepted and is evaluated here. It is determined that the doctoral thesis published by Bussau (1993) satisfies the criteria of publication outlined in Article 8 of the Code, and that all nomenclatural acts published in it satisfy the criteria of availability outlined in Articles 11 and 13 of the Code. The correct authority for all nomina first published in Bussau (1993) is ‘Bussau, 1993’, and not ‘Bussau, 1995’ or ‘Bussau & Vopel, 1999’. All nomenclatural acts published in Bussau (1995) and Bussau & Vopel (1999) are junior objective synonyms of acts published in Bussau (1993), except for Bathynox Bussau & Vopel, 1999. Nox Bussau, 1993 is a junior homonym of Nox Nalbant, 1986, and was provided the available new replacement nomen Bathynox Bussau & Vopel, 1999. The correct authority of Bathynox clavata is ‘(Bussau, 1993)’.

    Abstract [en]

    A new genus Neocamacolaimus gen. n., with one new species N. parasiticus gen. n., sp. n. is described from the benthic polychaete Sphaerosyllis cf. hystrix collected in the Skagerrak off the west coast of Sweden. Neocamacolaimus gen. n. is placed in the family Camacolaimidae and is particularly characterised by having annulated cuticle with lateral alae; seti- form cephalic sensilla located at level with amphids; amphidial fovea ventrally spiral; buccal cavity without armament; pharynx muscular; nerve ring located at base of pharynx; male reproductive system diorchic with outstretched testes; spic- ules weakly arcuate with straight manubrium; gubernaculum absent; alveolar supplements located in the pharyngeal re- gion; tubular supplements absent; tail conoid; caudal glands and spinneret present. Juveniles of this genus are particularly characterised by their parasitic lifestyle and the following unique morphological features: lips form a dorso-ventrally elon- gated perioral disc with internal sclerotizations: one midventral and two dorsosublateral (right and left); cephalic sensilla setiform, subventral sensilla are noticeably longer than the subdorsal ones; intestine extends posterior to rectum and anal opening, forming a post-anal pouch.

    Yeatesinia barbata gen. n., sp. n. (Nematoda: Plectida: Plectidae), a most remarkable nematode from New Zealand2014Ingår i: Nematology (Leiden. Print), ISSN 1388-5545, E-ISSN 1568-5411, Vol. 16, s. 953-962Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The new genus and species Yeatesinia barbata gen. n., sp. n. is described from a sand dune habitat in New Zealand. The new genus is characterised by a body length of 299-357 μm in females and 304-361 μm in males, lip region rounded dorso-ventrally, broad laterally, dorsally inclined, lateral sides of lip region with two large, horn-like, projections, each bearing one seta at its base, each amphid surrounded by three setiform sensilla, oral opening a broad transverse slit located on the dorsal body surface, and different structure of cuticle in the dorsal and ventral body sectors. This combination of unique morphological characters clearly separates the new genus from all other members of the Plectidae. The phylogenetic affinities of Yeatesinia gen. n. and its relationships to other genera of the family Plectidae are discussed.

    Phylogeny, biogeography and taxonomic consequences in a bird-of-paradise species complex, Lophorina-Ptiloris (Aves: Paradisaeidae)2017Ingår i: Zoological Journal of the Linnean Society, ISSN 0024-4082, E-ISSN 1096-3642, Vol. 181, nr 2, s. 439-470Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Biogeographical history and taxonomic delimitation in the Australo-Papuan bird-of-paradise Lophorina-Ptiloris species complex is examined with a combination of DNA and morphological markers. The results suggest that the complex started to diverge in the mid-Pliocene, driven by initial isolation and adaptation to altitudinally different habitats. As in many other New Guinean avian taxa, phylogeographic structure is more varied in montane Lophorina than foothill Ptiloris. With the exception of populations of Lophorina in the eastern New Guinean cordillera, phylogenetic patterns from molecular data and morphological discontinuities are consistently concordant, as are molecular species delimitation tests with previous morphology-based circumscription of taxa in Ptiloris. In Lophorina, however, both molecular data and significant, re-discovered morphological traits identify several taxa as more deeply differentiated than hitherto thought. Accordingly, we use these data in an integrative taxonomic approach to re-delimit taxa in the entire clade, including the recognition of three species in the previously monospecific Lophorina. In Lophorina, the identity of several type specimens is reviewed, one new subspecies is described from the Vogelkop, and the identity of the species name superba Pennant is resolved by neotypification, with correction of its author.

    No Signs of Genetic Erosion in a 19th Century Genome of the Extinct Paradise Parrot (Psephotellus pulcherrimus)2019Ingår i: DIVERSITY-BASEL, Vol. 11, nr 4Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Paradise Parrot, Psephotellus pulcherrimus, was a charismatic Australian bird that became extinct around 1928. While many extrinsic factors have been proposed to explain its disappearance, it remains unclear as to what extent genetic erosion might have contributed to the species’ demise. In this study, we use whole-genome resequencing to reconstruct a 15x coverage genome based on a historical museum specimen and shed further light on the evolutionary history that preceded the extinction of the Paradise Parrot. By comparing the genetic diversity of this genome with genomes from extant endangered birds, we show that during the species’ dramatic decline in the second half of the 19th century, the Paradise Parrot was genetically more diverse than individuals from species that are currently classified as endangered. Furthermore, demographic analyses suggest that the population size of the Paradise Parrot changed with temperature fluctuations during the last glacial cycle. We also confirm that the Golden-shouldered Parrot, Psephotellus chrysopterygius, is the closest living relative of this extinct parrot. Overall, our study highlights the importance of museum collections as repositories of biodiversity across time and demonstrates how historical specimens can provide a broader context on the circumstances that lead to species extinctions.

    The century old taxonomic confusion surrounding Wiedemannia zetterstedti Fallén and related species is resolved (Diptera: Empididae): Revision of the W. zetterstedti group2022Ingår i: Insects, E-ISSN 2075-4450, Vol. 13, nr 5, s. 460-460Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Wiedemannia zetterstedti species group is revised after examination of all available type specimens and includes one new species (W. ulrichi Ivković & Sinclair sp. nov.) and four redescribed species (W. czernyi (Bezzi), W. longipennis (Mik) stat. rev., W. rufipes (Oldenberg) stat. rev. and W. zetterstedti (Fallén)). The following new synonyms are proposed: W. (Roederella) ouedorum Vaillant, 1952 = W. czernyi (Bezzi, 1905); Paramesia riparia Robert, 1836 = W. zetterstedti (Fallén, 1826). Lectotypes are designated for the following species/subspecies: Atalanta hirtiloba Speiser, Brachystoma escheri Zetterstedt, Clinocera czernyi Bezzi, Clinocera longipennis Mik, Paramesia riparia Robert, and Roederia czernyi rufipes Oldenberg. In addition to morphological evidence, molecular species concepts were investigated using a molecular phylogenetic divergence-based species delimitation (bPTP) and results confirmed the morphological conclusions. A key to species is presented and geographic distributions are mapped.

    An integrative insight into the synsacral canal of fossil and extant Antarctic penguins2022Ingår i: Integrative Zoology, ISSN 1749-4869, E-ISSN 1749-4877, ISSN 1749-4877, Vol. 18, nr 2, s. 237-253Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The lumbosacral-canal system in birds most likely operates as a sense organ involved in the control of balanced walking and perching, but our knowledge of it is superficial. Penguins constitute interesting objects for the study of this system due to their upright walking, but only the Humboldt penguin, Spheniscus humboldti, and some incomplete fossil penguin synsacra have been studied in this respect. Here, we give an integrative comparative insight into the synsacral canal of extant Emperor penguin, Aptenodytes forsteri, Adelie penguin, Pygoscelis adeliae, and Eocene giant Anthropornis and/or Palaeeudyptes Antarctic penguins, using computed tomography imaging and associated data-extraction methodologies, complemented by analytical approaches ranging from geometric morphometrics to modularity, curvature, and wavelet analyses. We document that the variability in the number of synsacro-lumbar vertebrae is evolutionarily conserved, and all studied synsacra possess osteological correlates of the lumbosacral-canal system. We also found that Eocene and extant Antarctic penguins were separable on the basis of the main direction of the shape-related (size-independent) variability within said system, and A. forsteri was unique in the entire studied set in terms of the relative cranial shift of this compound structure. Moreover, we suggest that the evolutionary processes, shaping both the terrestrial posture and gait, were responsible, in extant penguins, for the increased simplicity and stability of the synsacral canal cross-sectional periodic patterns, as well as pave the way for the lumbosacral-canal system modularity characterized by reduced atomization/complexity.

    A neotype for Pontoscolex corethrurus (Muller, 1857) (Clitellata)2019Ingår i: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 4545, nr 1, s. 124-132Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Following many decades of work on the taxonomy, biology and ecology of the globally-distributed tropical earthworm Pontoscolex corethrurus (Muller, 1857), morphological and molecular data have shown that the stability and effectiveness of nomenclature depends on the designation of a neotype from the type locality. We do that, with all the required justifications, and provide sufficient information to permit the correct identification of this species.

    Abstract [sv]

    På Naturhistoriska riksmuseet finns många vackra och intressanta fåglar som besökarna kan titta på i utställningarna. De allra flesta fåglar som förvaras på museet finns dock i särskilda låsta utrymmen som bara personalen har tillgång till. I detta reportage får vi följa med museets fågelintendent på en vandring bakom kulisserna. Vi får se några av de tiotusentals föremål som finns bevarade här och lära oss om vikten av att ha samlingar.

    Abstract [sv]

    Varje år skickas 500-600 döda fåglar in till Naturhistoriska riksmuseet och lika många däggdjur. Det här reportaget fokuserar så klart på fåglarna och beskriver förvandlingen från kadaver till ett ovärderligt museiföremål som förhoppningsvis ska bevaras i de vetenskapliga samlingarna för evigt. Här kan du som fågelintresserad också lära dig hur du kan bidra till dessa samlingar om du någon gång skulle hitta en död fågel.

    Molecular phylogeny of Sericostomatoidea(Trichoptera) with the establishment of three newfamilies2017Ingår i: Systematic Entomology, ISSN 0307-6970, E-ISSN 1365-3113, Vol. 42, s. 240-266Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We inferred the phylogenetic relationships among 58 genera of Sericostom-atoidea, representing all previously accepted families as well as genera that were notplaced in established families. The analyses were based on ve fragments of the proteincoding genes carbamoylphosphate synthetase (CPSase of CAD), isocitrate dehydroge-nase (IDH), Elongation factor 1a (EF-1a), RNA polymerase II (POL II) and cytochromeoxidase I (COI). The data set was analysed using Bayesian methods with a mixedmodel, , and parsimony. The various methods generated slightly different resultsregarding relationships among families, but the shared results comprise support for: (i)a monophyletic Sericostomatoidea; (ii) a paraphyletic Parasericostoma due to inclusionof Myotrichia murina, leading to synonymization of Myotrichia with Parasericostoma;(iii) a polyphyletic Sericostomatidae, which is divided into two families, Sericostom-atidae sensu stricto and Parasericostomatidae fam.n.; (iv) a polyphyletic Helicophidaewhich is divided into Helicophidae sensu stricto and Heloccabucidae fam.n.; ( v) hypoth-esized phylogenetic placement of the former incerta sedis genera Ngoya, Seselpsycheand Karomana; (vi) a paraphyletic Costora (Conoesucidae) that should be divided intoseveral genera after more careful examination of morphological data; (vii) reinstatementof Gyrocarisa as a valid genus within Petrothrincidae. A third family, Ceylanopsychi-dae fam.n., is established based on morphological characters alone. A hypothesis ofthe relationship among 14 of the 15 families in the superfamily is presented. A key tothe families is presented based on adults (males). Taxonomic history, diagnosis, habitatpreference and distribution data for all sericostomatoid families are presented.

    Structure of insect community in the fungus Inonotus radiatus in riparian boreal forests2016Ingår i: Journal of Natural History, ISSN 0022-2933, E-ISSN 1464-5262, Vol. 50, s. 1613-1631Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Basidiomes of polypore fungi host many insects. Yet systematic information about insect assemblages from most fungal species is lacking. We studied the insect community associated with the wood-decaying fungus Inonotus radiatus (Sowerby: Fr.) P. Karst. (Hymenochaetales). More specifically, we studied the effect of successional stage and weight of basidiomes, as well as shore exposition (north or south), on species richness and composition, as well as occurrence and abundance of the most abundant fungivores. Basidiomes were collected from riparian forests at five lakes in Sweden. Insects were reared out from the basidiomes in the laboratory. A total of 5645 adult insect individuals of 117 taxa were obtained. Among these, 2782 specimens of 36 taxa use Inonotus radiatus basidiomes as breeding habitat. Eight species of parasitic wasps were new to Sweden. The most abundant fungi- vore was Ennearthron cornutum (Ciidae), which is a generalist breeding in many polypore species. Based on our material and literature, the melandryid beetles Abdera affinis and A. flexuosa seem to be specialists on the order Hymenochaetales. Other fre- quent fungivores were Dorcatoma dresdensis (Ptinidae), and the lepidopterans Archinemapogon yildizae, Nemapogon cloacellus and N. picarellus (Tineidae). The parasitoid community associated with the tineid moths was similar to the community associated with the other polypore species in the order Polyporales. In contrast, the parasitoids associated with Dorcatoma (and/or Abdera) were dif- ferent from the other Polyporales species, suggesting that the fungal host species is more important for these parasitoid species than the beetle host species itself. The most abundant and fre- quent parasitoids were the braconids Diospilus dispar and Colastes fritzeni, which both parasitise Dorcatoma. Species richness was significantly smaller in fresh than in more decayed basidiomes, but species composition did not differ. There was no difference in species composition or richness between north and south shorelines.

    Complete subspecies-level phylogeny of the Oriolidae (Aves: Passeriformes): Out of Australasia and return2019Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 137, s. 200-209Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Old World orioles (Oriolidae) are medium-sized passerine birds confined largely to forested areas of Africa, Eurasia and Australasia. We present a new complete molecular (mtDNA) subspecies level phylogeny of the Oriolidae including all 113 taxa (35 species) together with a backbone phylogeny of 19 taxa from the main Oriolus clades based on (i) 21 nuclear genes, (ii) whole mito-genomes, and (iii) genome-wide ultraconserved elements. We use this phylogeny to assess systematic relationships and the biogeographical history of this avian family. Furthermore, we use morphological measurements to investigate the relationship between size and shape axes and upstream or back-colonization of this extensive island region from Asia. We show that several subspecies or groups of subspecies may warrant species rank and we find a continental example of two morphologically distinct species (O. mellianus/O. traillii) being genetically (mtDNA) very similar. Biogeographically, we confirm previous findings that members of the Oriolidae originated in Australo-Papua. Dispersal out of this area took place around 15 Mya to southeast Asia and Africa, and from Africa to the Palearctic followed by recolonization of the Indonesian and Philippine island region during the Plio-Pleistocene. Recolonisation of the Indonesian and Philippine islands coincided with an increase in body size, which may have facilitated the ability to co-exist with other congenerics.
