    Annotated catalog of Vietnamese Trichoptera (Insecta)2023In: Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, ISSN 0237-5419, E-ISSN 2063-1588, Vol. 54, no Supplementum 1, p. 1-160Article in journal (Refereed)
    Abstract [en]

    All 835 valid species of caddisflies recorded from Vietnam by the end of 2021 are cataloged. The catalog is annotated with information about reference to original description where the species was described, type locality, depository institution of the type material, habitat where the species has been collected, and distribution. The distribution section covers all countries as well as Vietnamese provinces from where species has been recorded. The catalog is based on records of about 7,600 individuals recorded in literature, of which 69 % of the individuals are males and 31 % are females. With 139 species recorded, the most species rich family in Vietnam is the Hydropsychidae, followed by the Philopotamidae, Leptoceridae and the Hydroptilidae. These four families comprise 50% of the species diversity of caddisflies in Vietnam. By number of species, the smallest families are the Phryganopsychidae and Brachycentridae (two species each) and the Sericostomatidae, Phryganeidae and Limnocentropodidae that are represented by only one species each.

    Abstract [en]

    The first Trichoptera recorded from New Caledonia were four species described by Kimmins in 1953, each in anew endemic genus. The diversity was increased to eight species with the publication by Sykora in 1967 of threenew species in two new genera and a fourth species in a previously established genus. Today, 239 valid species areknown from the country, representing 20 genera in 10 families. Analysis of published records for some 32,000Trichoptera specimens collected from 291 localities shows that the highest species diversity is in the SE part of theGrande Terre, and that species diversity is greatest at lower altitudes, i.e. 0–200 meters above sea level. We also seethat the three most frequently collected families (85% of the individuals) in the sampled material are Hydroptilidae(35%), followed by Hydropsychidae (27%), and Leptoceridae (22%). Phylogenetic analyses have demonstratedthat the first species to occupy the island and the earliest radiations took place on areas covered by ultrabasicsubstrate, which is poor in nutrients and rich in certain toxic heavy metals.

    Lineage sorting by parameres in Limnephilinae subfamily (Trichoptera): with description of a new tribe, new genera and new species2019In: Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, ISSN 0237-5419, E-ISSN 2063-1588, Vol. 50, no S1, p. 3-98, article id 31329FBB-5B10-4B5E-8F7D-56DA267CAD78Article in journal (Refereed)
    Abstract [en]

    The discovery of the new Agaphylax genus with unique paramere organisation has initiated our lineage sorting oftribes by parameres in the Limnephilinae subfamily applying the principles and procedures of fine phenomics in order toestablish transformation series of the polarized plesiomorphy-apomorphy character states for each limnephiline genera.According to the extraordinary high diversity the paramere that is the stimulatory and titillating structure of the phallic organis a speciation supertrait. This adaptive trait is directly involved in the processes of reproductive isolation and diverging assubtle initial split of lineages producing the incipient sibling species in the recent past of contemporary speciation processes.Contrary, the drastic divergence of the Agaphylax plated paramere is much older, similarly to the many-spined parameres ofthe Hesperophylacini tribe. It has been initiated by drastic combined and synchronous external and internal stochastic effects,processed in ancestral sexual integrative adaptation as well as organised and fixed in older and deeper coalescence events andappears as a character with tribe ranking potential. To open a wider perspective, a systemic relational analysis is required inthe future including other adaptive or neutral character transformation series, due to the burden of taxonomic incongruencesgrounded by chimerism in stochastic genetic reticulation. Traits of species are mixed products coming from various sources.Only character combinations can and ought to be analysed in terms how to classify taxa. We have polarized eight genitaliccharacters additional to parameres for a future analysis of the potential of character combinations.Limnephilinae subfamily is composed of Limnephilini, Chilostigmatini, Chaetopterygini, Stenophylacini and Hesperophylacinitribes and here we established the new Agaphylacini tribe. Based on parameres we have delineated taxa in lineagesorting and described two new genera: Fogophylax gen. nov., Simaphylax gen. nov. and fourteen new species: Anaboliaalsoja, A. hepehupa, Asynarchus kimaros, Limnephilus kerekes, L. maghrebensis, L. oblos, Homophylax beges, H. coros,Chaetopteroides plackovicensis, C. rilaensis, Allogamus ketpar, Platyphylax beshkovi, Pycnopsyche letova and P. telea spp.nov. The by-product of this survey is a world atlas of paramere drawings for the entire Limnephilinae subfamily.

    Revision of European Wormaldia species (Trichoptera, Philopotamidae):Chimeric taxa of integrative organisation2019In: Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, ISSN 0237-5419, E-ISSN 2063-1588, Vol. 50, no 1, p. 31-85Article in journal (Refereed)
    Abstract [en]

    We have recognised significant incongruences among the most commonly used taxonomic characters in theEuropean species of Wormaldia genus of the Philopotamidae caddisfly family. During taxonomical analysis and rankingprocedures we have recorded incongruent, discorcordant characters also in the taxa in Rhyacophilidae, Hydropsychidae andLimnephilidae caddisfly families. Based on theoretical background we concluded that taxa of examined caddisflies andprobably all living creatures are chimeric entities composed of components of different origin. Genomes and phenomes aretree-like on the surface but more reticulated in the deep. We understand chimerism with universal consequences, expandingwell beyond the evolutionary tree-thinking of reductionism and determinism. Taxa are chimeric or at least chimerical in astochastic universe under the permanent fluxes of the external and internal impacts created by intercourses between entropyand energy gradients. We have surveyed how to create and correct synonymies in the splitter/lumper perspectives along theprinciples of compositional and specification hierarchies understood as quantitative variability of non-adaptive neutral andqualitative stability of adaptive, non-neutral traits. We outlined how the apophantic (declaratory) hybris creates synonymiesand underestimates biodiversity. After redrawing the diverging genitalic structures, particularly the speciation traits we havereinstated species status of eight taxa: W. trifida Andersen, 1983 stat.restit, stat. nov., W. albanica Oláh, 2010 stat. restit., W.bulgarica Novak, 1971 stat. nov., W. daga Oláh, 2014 stat. restit., W. graeca Oláh, 2014 stat. restit., W. busa Oláh, 2014 stat.restit., W. homora Oláh, 2014 stat. restit. W. nielseni Moretti, 1981 stat. nov. Character selection and lineage sortingprocedures established the following species groups, species complexes and species clades in the European species ofWormaldia: W. occipitalis species group: W. occipitalis species complex; W. charalambi species group; W. copiosa speciesgroup; W. triangulifera species group: W. bulgarica species complex, W. khourmai species complex, W. subnigra speciescomplex: W. asterusia species clade, W. subnigra species clade, W. vercorsica species clade; W. triangulifera speciescomplex, W. variegate species complex. Unplaced species: W. ambigua, W. algirica, W. sarda. In this revision we havedescribed fourteen new species: W. longiseta, W. carpathica, W. kurta, W. parba, W. foslana, W. kumanskii, W. libohova, W.silva, W. gorba, W. kera, W. rona, W. sima, W. granada, W. telva.

    On the Trichoptera of Korea with Eastern Palaearctic relatives2018In: Opuscula Entomologica Budapest, Vol. 49, no 2, p. 99-139Article in journal (Refereed)
    Abstract [en]

    The caddisfly materials collected by Hungarian zoologists during 25 collecting trips between the years of 1970 and2016 in the Korean Peninsula was identified and compared when required with Eastern Palaearctic relatives. The appendiculargenital terminology was adopted and applied to several representatives of Polyphorae taxa. We identified 95 caddisflyspecies, including 5 new records for the Korean Peninsula: Tinodes higashiyamanus Tsuda, 1942, Apatania yenchingensis Ulmer, 1932, Neophylax relictus (Martynov, 1935), Limnephilus quadratus Martynov, 1914, and Hydatophylax soldatovi (Martynov, 1914). We have described the following 12 species new to science: Plectrocnemia ussurica Oláh & Johanson sp.nov. (Russia); Psychomyia tompa Oláh & Johanson sp. nov. (Russia); Psychomyia vandor Oláh & Johanson sp. nov.(Russia); Agapetus vastag Oláh & Johanson sp. nov. (Russia); Agapetus vekon Oláh & Johanson sp. nov. (Russia);Neophylax goguriensis Oláh & Park sp. nov. (North Korea); Neophylax sillensis Park & Oláh sp. nov. (South Korea); Dicosmoecus coreanus Oláh & Park sp. nov.

    Revision of the European Rhyacophila fasciata species complex by fine phenomics of the paramere (Trichoptera, Rhyacophilidae)2020In: Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, ISSN 0237-5419, E-ISSN 2063-1588, ISSN 2063-1588, Vol. 51, no 1, p. 21-54Article in journal (Refereed)
    Abstract [en]

    The poorly known, so called widely distributed and highly varying species of the European Rhyacophila fasciata species complex are revised by fine phenomics of the paramere organisation. In this species complex paramere is the most diverse organ. It is the speciation trait integrating the initial split of speciation by its stimulatory and titillating function involved in the early processes of reproductive isolation. Based on paramere organisation and on the character state of distribution three lineages have been delineated in the Rhyacophila fasciata species complex: the European R. fasciata lineage, the Caucasian R. aliena lineage and the R. mysica lineage distributed from Albania to Pakistan. In the R. fasciata lineage we have distinguished three clades of species: R. fasciata with five species, R. matrensis with seven species, and R. denticulata with seven species. We have re-diagnosed three known species: R. fasciata Hagen, 1859, R. denticulataMcLachlan, 1879, R. sociata Navas, 1916 and described 15 species new to science: R. biharensis Oláh sp. nov., R. bulgarica Oláh sp. nov., R. coppai Oláh sp. nov., R. csornahorensis Oláh & Szczęsny sp. nov., R. ferda Oláh sp. nov., R. kopasa Oláh & Coppa sp. nov., R. matrensis Oláh, & Szczęsny sp. nov., R. retezatensis Oláh sp. nov., R. rova Oláh & Coppa sp. nov. R. ruda Oláh & Johanson sp. nov., R. salfa Oláh sp. nov., R. soreda Coppa & Oláh sp. nov. R. suna Oláh sp. nov., R. tuhega Oláh sp. nov., R. zemplenensis Oláh sp. nov. The species status of Rhyacophila gemella Navas, 1923 was reinstated.

    On the Diplectroninae and Hydropsychinae (Trichoptera) of India, with related taxa. A tribute to Fernand Schmid2021In: Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, ISSN 0237-5419, E-ISSN 2063-1588, Vol. 52, p. 003-196Article in journal (Refereed)
    Abstract [en]

    The overall declining state of the western taxonomy is clearly documented by the present fate of the extremely high valued and huge unidentified caddisfly material collected in India and deposited in the Canadian National Collection. Due to the general lack of both financial and scientific resources in taxonomy, this huge collection remained almost untouched during the last 70 years after its collection. With a tribute to the collector, Fernand Schmid, the great caddisfly collector and taxonomist we have reconstructed his collecting activities of the five years in India by geolocalization and elaborated about ten percent of his undetermined Hydropsychidae in the Diplectroninae and Hydropsychinae subfamilies. Description of 145 new species from this small fragment of the huge unidentified collection demonstrates a pronounced underestimation of the biodiversity in general, routinely measured by gross phenomics. During this study we have reinstated the species status of seven taxa: Diplectrona kirimaduhela Schmid, 1958, stat. restit., Cheumatopsyche rienga Oláh & Johanson, 2008, stat. restit., Cheumatopsyche amurensis Martynov, 1934, stat. restit., Cheumatopsyche banksi Mosely, 1942, stat. restit., Cheumatopsyche processuata (Martynov, 1927), stat. restit., Potamyia klakahana (Ulmer, 1951), stat. restit., Potamyia proboscida Li & Tian, 1996, stat. restit., and raised the subspecies status to species rank of Diplectrona stigmatica Banks, 1937, stat. nov. Furthermore, we have etablished four new species groups, sixteen new species complexes and described 145 new species as follows: Diplectrona aurovittata new species group: D. hasada new species complex: D. bandara sp. nov., D. borghata sp. nov., D. chiangma sp. nov., D. chingsa sp. nov., D. daotama sp. nov., D. grimona sp. nov., D. jaraina sp. nov., D. khopurna sp. nov., D. khumyara sp. nov., D. kualagomba sp. nov., D. kurlingha sp. nov., D. lyngkota sp. nov., D. mawkhapa sp. nov., D. mirgona sp. nov., D. muktapura sp. nov., D. mynsoa sp. nov., D. nongina sp. nov., D. nongra sp. nov., D. nongronga sp. nov., D. sirkasha sp. nov., D. sironga sp. nov., D. sumatrana sp. nov., D. tairenpokpa sp. nov., D. tungpa sp. nov., D. tamdaophila new species complex: D. aisahka sp. nov., D. beluma sp. nov., D. dhampa sp. nov., D. dhankuta sp. nov., D. huishua sp. nov., D. khasiaca sp. nov., D. khasigupta sp. nov., D. madonga sp. nov., D. meghalaya sp. nov., D. mopaenga sp. nov., D. parala sp. nov., D. rumkhenga sp. nov., D. sitahoana sp. nov., D. sohra sp. nov., D. coalescens species group: D. hongkonga sp. nov., D. kattalaimala sp. nov., D. shimoga sp. nov., D. gombak new species group: D. albofasciata new species complex, D. fasciata new species complex: D. buitenzorga sp. nov., D. panaona sp. nov., D. simalura sp. nov., D. tonkulana sp. nov., D. wailima sp. nov., D. gentinga new species complex: D. gentinga sp. nov., D. gombak new species complex: D. barisana sp. nov., D. merangira sp. nov., D. phanoma sp. nov., D. temengora sp. nov., D. tengaha sp. nov., D. taprobanes new species group: D. abmaka sp. nov., D. kambaita sp. nov., D. kamikarka sp. nov., D. koda sp. nov., D. komadia sp. nov., D. madhya sp. nov., D. satanwada sp. nov., D. sirtranga sp. nov., D. tienmua sp. nov., D. umlanga sp. nov., Cheumatopsyche lepida species group: C. assamha sp. nov., C. fordula sp. nov., C. madpradha sp. nov., C. manimapa sp. nov., C. pondora sp. nov., C. puramukta sp. nov., C. purmapa sp. nov., C. sohkha sp. nov., C. swampa sp. nov., C. dubitans species group: C. mawpya sp. nov., C. excisa species group: C. chuga sp. nov., C. costalis species group: C. dangchura sp. nov., C. kamposka sp. nov., C. lagaironga sp. nov., C. mawjana sp. nov., C. mawprana sp. nov., C. nonga sp. nov., C. nongajra sp. nov., C.oinamla sp. nov., C. salaka sp. nov., C. yunnana sp. nov., C. concava species group: C. haflonga sp. nov., C. kambirona sp. nov., C. khasia sp. nov., C. korosa sp. nov., C. myntanga sp. nov., C. nongrima sp. nov., C. chinensis species group: C. bandarkhala sp. nov., C. delhia sp. nov., C. hanoia sp. nov., C. hotaya sp. nov., C. pega sp. nov., C. quangchua sp. nov., C. tamda sp. nov., C. tongoma sp. nov., C. holzschuhi species group: C. apuma new species complex: C. apuma sp. nov., C. nyukma sp. nov., Potamyia czekanovskii species group: P. flavata new species complex: P. binhoa sp. nov., P. chitwana sp. nov., P. congsa sp. nov., P. moccha sp. nov., P. nikalandugola species complex: P. hasalaka sp. nov., P. tamilnada sp. nov., P. chinensis species group, P. flava species group: P. dinamla sp. nov., P. trenhona species group: P. barata sp. nov., P. jinhongensis new species complex: P. dhauliana sp. nov., P. yunnanica new species complex: P. namha sp. nov., P. namkhana sp. nov., P. topali sp. nov., P. umbaso sp. nov., P. vietnama sp. nov., Hydromanicus hermosus species group: H. flavoguttatus species complex: H. bukit sp.nov., H. mawpyut sp. nov., H. mawshun sp. nov., H. luctuosus species group nom. nov.: H. asor new species complex: H. shilliang sp. nov., H. eleasar new species complex: H. kambaitiensis sp. nov., H. kamengensis sp. nov., H. kashong sp. nov., H. sikkimensis sp. nov., H. tibetensis sp. nov., H. inferior new species complex: H. darban sp. nov., H. hasad sp. nov., H. jakhand sp. nov., H. khalband sp. nov., H. mattiyang sp. nov., H. mynso sp. nov., H. nondeng sp. nov., H. luctuosus species complex: H. fureses sp. nov., H. garhwal sp. nov., H. khopum sp. nov., H. laitlyn sp. nov., H. manilon sp. nov., H. mapum sp. nov., H. pufok sp. nov., H. thangrain sp. nov., H. tharauyang sp. nov., H. tiyang sp. nov., H. tungnath sp. nov., H. umbonatus new species complex: H. kover sp. nov., H. manisir sp. nov., H. ronghongkung sp. nov., H. sirohis sp. nov., H. spatulatus species group: H. rahung sp. nov., H. spatulatus species cluster.

    Molecular phylogenetics reveals novel relationships within Empidoidea (Diptera)2018In: Systematic Entomology, ISSN 0307-6970, E-ISSN 1365-3113, Vol. 43, p. 619-636Article in journal (Refereed)
    Abstract [en]

    Empidoidea represent a large and diverse superfamily of true flies, and to date no stable hypothesis on the phylogeny exists. Previous classifications have been based on morphological data and the relationships among several groups are still unknown. Using the mitochondrial genes cytochrome oxidase c subunit I (COI) and cytochrome β (Cytβ) and the nuclear genes carbomoylphosphate synthase domain of rudimentary (CAD), elongation factor‐1α (EF‐1α) and isocitrate dehydrogenase (IDH) in a Bayesian analysis, we tested the support of higher taxonomic groups within this large superfamily of flies. We re‐evaluated previous hypotheses of evolution within the group and present a highly supported phylogenetic hypothesis. Atelestidae, Dolichopodidae, Empididae and Hybotidae were supported as monophyletic families, with Atelestidae as sister group to the remaining Empidoidea. Within the family Hybotidae, Bicellariinae stat.n. formed the sister group to the other subfamilies. The family Ragadidae stat.n. is established to include the subfamily Ragadinae and the new subfamily Iteaphilinae subfam.n.; Ragadidae was sister group to the Empididae. Dolichopodidae was found to form a sister group to Ragadidae plus Empididae. Within Empididae, Hemerodromiinae was found to be a nonmonophyletic group. The tribes Hilarini and Hemerodromiini stat. rev. were recovered as sister groups, as were Empidini and Chelipodini stat. rev. The former family Brachystomatidae was found to be nested within Empididae. A revised classification and diagnoses of nondolichopodid families, subfamilies and tribes are provided.

    Review of New Caledonian species of Oxyethira Eaton,with description of 17 new species, and new recordsfor Hydroptila Dalman and Hellyethira Neboiss(Trichoptera, Hydroptilidae).2015In: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, Vol. 530, p. 37-90Article in journal (Refereed)
    Abstract [en]

    New Caledonian representation of the cosmopolitan genus Oxyethira Eaton is reviewed, with the descriptionof new species bringing to 26 the total for the genus on the island. The species are referred to threesubgenera: Trichoglene Neboiss (11 species), Pacificotrichia Kelley (13 species) and Dampfitrichia Ulmer(one species) and one species is unplaced to subgenus. A key is provided to Oxyethira species of New Caledonia.In addition, new records are given for two otherwise Australian species, Hydroptila losida Moselyand Hellyethira malleoforma Wells. Points marked on a series of small maps of New Caledonia indicate thesite or sites at which the species were collected. This final paper in a series of generic revisions brings thehydroptilid fauna of the island of New Caledonia to 60 species, distributed in six genera.

    Why are so many species based on a single specimen?2019In: Zoosymposia, ISSN 1178-9905, E-ISSN 1178-9913, Vol. 14, p. 32-38Article in journal (Refereed)
    Abstract [en]

    A considerable number of insect species, including Trichoptera, are described from a single specimen, also knownas a 'unique' or a 'singleton'. We ask the question of whether this reflects failure to consider variation and relatedspecies, lack of collecting effort, or true rarity. In an attempt to answer this question we examine the availableliterature and data on the Trichoptera of Tasmania and New Caledonia. We note a low level of taxonomicsynonymy among species in these faunas. Moreover, a significant proportion of species from Tasmania that werebased originally on singletons have been re-collected subsequently, but this is not true for New Caledonia. Thepossible significance of these figures is considered following examination of data on diversity and abundance ofHydroptilidae collected by regular, standardised light trapping over almost two years at a northern Australiantropical stream. We conclude that quite a large proportion of the Trichoptera species based on singletons are rare,valid species, but for others the appearance of rarity may be a consequence of inadequate collecting, particularbehavioural attributes of the species, including seasonality, and failure to consider fully the structural diversity ofrelated species. Lastly, we discuss briefly the consequences of rarity, apparent or real, on conservationmanagement.
