Two previously unrecognized species attributable to the genus Kontrimavichusia Makarikov & Binkienė, 2022 in arvicoline rodents from the North Caucasus are described. Kontrimavichusia testiculata sp. nov. is described from Microtus majori (Thomas, 1906) from the northwestern Caucasus (Republic of Adygeya and Karachay-Cherkess Republic, Russia) and Kontrimavichusia hobergi sp. nov. is described from Microtus daghestanicus (Shidlovsky, 1919) from the central Caucasus (Republic of North Ossetia, Russia). Kontrimavichusia testiculata is readily distinguishable from K. asymmetrica (Janicki, 1904) and K. hobergi in having a larger number of testes (4–6 per proglottis), larger suckers and a longer cirrus and cirrus-sac. In addition, the new species differs from its congeners by the position of the cirrus-sac with regard to the poral osmoregulatory canals and position of distal end of the rostellar pouch relative to the posterior margins of the suckers. Kontrimavichusia hobergi can be readily distinguished from its congeners by the arrangement of the testes in a triangle and the position of the cirrus-sac with regard to the poral osmoregulatory canals. In addition, this previously unrecognized species differs from K. asymmetrica and K. testiculata by the smaller dimensions of the fully developed strobila and a narrower ovary. The cirrus-sac of K. hobergi is larger than that in K. asymmetrica but smaller than that in K. testiculata. We also used partial sequences of the nuclear ribosomal 28S rRNA gene and mitochondrial nad1 gen to justify the generic arrangement and independent status of these two new species which are characterized in the current manuscript.
The genus Lissocnemis Kohl, 1907 of the subfamily Ctenocerinae is recorded from Korea for the first time. The diagnosis and characteristics of the genus, description of a new species, L. koreana Kim & Shimizu sp. nov. and redescription of another species, L. brevipennis hitherto known from Southeast Asia and Japan, are presented. The biogeographical distribution of the genus is discussed. Cryptosalius Turner, 1917 (type species: Pseudagenia rava Bingham, 1896; in part) and Dinagenia Banks, 1934 (type species: D. apollo Banks, 1934) are synonymized with Lissocnemis and the following new combinations are made: Lissocnemis tonkinensis (Turner, 1920) comb. nov. (= Cryptosalius tonkinensis Turner, 1920); Lissocnemis apollo (Banks, 1934) comb. nov. (= Dinagenia apollo Banks, 1934); and Lissocnemis satyrus (Banks, 1938) comb. nov. (= Dinagenia satyrus Banks, 1938). Lastly, L. satyrus (Banks, 1938) and L. nigricoxis Haupt, 1941 are rendered to be junior synonyms of L. apollo (Banks, 1934) comb. nov.
Due to the fragility of the ophiuroid (brittle star) skeleton, the bulk of the group’s fossil record consists of dissociated ossicles preserved as microfossils. In spite of their great potential as basis for taxonomic and phylogenetic studies, however, ophiuroid ossicles from the Paleozoic have received very little attention so far. Here, we provide an exhaustive taxonomic assessment of such fossils retrieved from sieving residues from the Silurian of Gotland, Sweden. This material was used in a previous study to describe two key taxa that allowed constraining the origin of the extant ophiuroid clade. The remaining taxa belonging to that same lineage are described in the present paper. The evidence at hand suggests that the stem of the extant ophiuroid clade was formed by two genera, Ophiopetagno and Ophiolofsson gen. nov., including six and five species, respectively, and spanning at least the upper Llandovery through upper Ludlow. We conclude that Ophiopetagno and Ophiolofsson represent sister genera that coexisted through most of the Silurian in the shallow tropical seas of Gotland. They underwent repeated body size reductions in correlation with environmental perturbations, with Ophiopetagno paicei eventually giving rise to Muldaster haakei; the first member of the living Ophiuroidea. Herein, we also introduce two new clades, Ankhurida clade nov. and Ophiovalida clade nov., and the following eight new species: Ophiolofsson joelmciveri gen. et sp. nov., O. obituary gen. et sp. nov., O. immolation gen. et sp. nov., O. archspire gen. et sp. nov., O. hendersonorum gen. et sp. nov., Ophiopetagno bonzo sp. nov., O. kansas sp. nov., O. doro sp. nov.; and two probably new species in open nomenclature: Ophiopetagno sp. 1, and Ophiopetagno sp. 2.
Among the 44 genera of predatory stink bugs (Asopinae) described for the Old World, there is a notable lack of recent studies. In this research, we aim to fill this gap by investigating the taxonomic history and morphology of species of Cantheconidea. As results, we present the redescription of the genus and validate three species: C. humeralis, C. javana and C. mitis comb. nov. A lectotype for C. mitis is designated and comments on the type material are given. Additionally, we transfer four species from Cantheconidea to the genus Eocanthecona: E. acuta comb. nov., E. variabilis comb. nov., E. gaugleri comb. nov. and E. insularis comb. nov. To accommodate the unique characteristics of Cantheconidea cyanacantha, we describe a new genus, Cantheconesia Brugnera & Roca-Cusachs gen. nov., and transfer the species, resulting in Cantheconesia cyanacantha gen. et comb. nov. Our study provides detailed redescriptions of species and accompanying images to support taxonomic decisions and presents new distribution records.
Exploration of macrofungi in the Jammu and Kashmir regions, India, led to the discovery of two novel species, described herein as Lactarius indohirtipes sp. nov. and L. sharmai sp. nov. This paper presents detailed morphological descriptions and illustrations, as well as a phylogenetic analysis based on nrITS sequences. A comparative analysis with related species is also included.
A comprehensive checklist and host plants of Aphididae (Aphidomorpha: Hemiptera) from Pakistan
(2024)
The family Aphididae (Hemiptera) represents one of the most diverse groups of sap-sucking insect pests referred to as aphids or plant-lice, with 366 species reported in Pakistan, associated with wide array of agricultural and horticultural crops, including fruit and forest trees, weeds, grasses, shrubs, and vines. This work aims to provide an updated checklist of aphids and their associated host plants documented across various regions of Pakistan. The checklist consolidates information from various published literature sources, including annotated checklists, regional distribution data, and host plant records from Pakistan. In this study, we present an annotated checklist of 366 aphid species, belonging to 134 genera and 11 subfamilies, associated with a total of 359 host plant species stretched over 84 families in Pakistan.
The monophyly of Theraphosinae is supported by both morphological and molecular phylogenies. However, intergeneric relationships often show polytomies and branches with low support. A previous phylogenetic study proposed an intergeneric relationship for the subfamily based on molecular data and divided it into three tribes: Grammostolini, Hapalopini and Theraphosini. However, not all genera of Theraphosinae were sampled, and some relationships were inferred based on morphological similarities. Regarding the Hapalopini from Brazil, the relationships of some genera are still uncertain, such as Kochiana, Catanduba, and Munduruku. In this paper, we describe four new species of Hapalopini from Brazil: Cyriocosmus paresi sp. nov., Hapalopus akroa sp. nov., H. guidonae sp. nov., and K. fukushimae sp. nov. In addition, we propose an updated diagnosis for these three genera and for the species K. brunnipes and M. bicoloratum.
Ophioderma teres (Lyman, 1860), an ophiuroid previously believed to have a wide distribution in the eastern Pacific, has been found to have an unclear taxonomic identity. While considered a well-known species, recent studies have revealed that O. teres lacks a holotype and has vague boundaries with its congeners Ophioderma teres unicolor H.L. Clark, 1940 and Ophioderma sodipallaresi Caso, 1986, as well as with two additional new morphotypes detected in Mexico and Nicaragua, causing continuous misidentifications. This study utilized an integrative taxonomy approach based on morphologic, morphometric, and molecular evidence to clarify the taxonomic status of O. teres, O. sodipallaresi, O. teres unicolor, and the two new morphotypes. Data integration led to the following results: 1) the neotype designation and redescription of O. teres; 2) the proposal of O. sodipallaresi as a junior synonym of O. teres; 3) the status change of O. unicolor stat. nov. from subspecies to species, and 4) the description of the morphotypes as the new species Ophioderma aija sp. nov. and Ophioderma bichi sp. nov. An identification key to the eastern Pacific species of Ophioderma was also developed. This work contributes to the knowledge of Ophioderma in the region, increasing the number of described species and providing resources for their accurate identification.
In this study, we describe two new species of Mesobiotus based on morphological data collected through light and scanning electron microscopy. Descriptions include DNA sequences of four commonly used molecular markers (18S rDNA, 28S rDNA, ITS-2, and COI). Mesobiotus efa sp. nov. was discovered in North-West Russia and belongs to the group of species with smooth cuticle, harmsworthi-type OCA, typical Mesobiotus claws IV with unindented lunules, and egg chorion with reticulated processes in form of ‘sharp wide cones’ or ‘cones with long slender endings’, egg process bases with well-developed crone of dark thickenings without finger-like projections, and egg shell surface between the processes with ridges without reticulation, areolation or semi-areolation. It can be distinguished from all know species of this group by a unique combination of morphological and morphometric characters. Mesobiotus vulpinus sp. nov. was found in the Russian Far East, and is similar to Mesobiotus mauccii by having an egg chorion with polygonal relief. The new species can be distinguished from M. mauccii by having a narrower buccal tube, by details of oral cavity armature, and by longer egg chorion processes. Furthermore, we provide results of the phylogenetic analyses of the genus Mesobiotus conducted in this study.
Although semi-aquatic cockroaches have been known for a long time, these insects remain little studied and their diversity underestimated. While a few species are known from Asia or South America, only a single one is known to be associated with water in Africa. Here, we report two species of semi-aquatic cockroaches of the subfamily Epilamprinae from Cameroon. One of these species is new: Rhabdoblatta fotoi Nyame Mbia, Legendre & Biram à Ngon sp. nov. Africalolampra camerunensis (Borg, 1902) comb. nov. was also found associated to these streams and we provide an extended description of this species, as well as for Africalolampra stipata comb. nov., also known from streams in West Africa. Another species was found in Cameroonian streams and is described here, although only identified at the family level (Blattellidae). The descriptions are based on morpho-anatomic characters, including male genitalia. Because nymphs were found primarily associated with water – more than adults – we provide a description of nymphs whenever possible. We provide molecular data (12S rRNA marker) for two of these water-associated species that we compared with published and unpublished sequences of Epilamprinae in a Maximum Likelihood approach. We also illustrate all but one species from continental Africa in the genera Africalolampra and Rhabdoblatta, including R. punctipennis (Saussure, 1895) which we reinstate. We provide a map and list of localities for Africalolampra and Rhabdoblatta spp. from continental Africa and Madagascar, as well as an identification key for species of Africalolampra. We finally discuss putative adaptations of semi-aquatic cockroaches.
Five new species of the spider genus Heteropoda Latreille, 1804 (Araneae: Sparassidae) from China
(2024)
Five new species of Heteropoda (Araneae, Sparassidae, Heteropodinae) are described from China: H. bawanglingensis sp. nov. (female; Hainan), H. dulongensis sp. nov. (male, female; Yunnan), H. hainanensis sp. nov. (male, female; Hainan), H. longa sp. nov. (female; Guizhou), and H. vaginalis sp. nov. (female; Yunnan). We provide descriptions and illustrations for each species as well as a distribution map in the current paper.
Scalibregmatidae Malmgren, 1867 is a family of annelids, with only few taxa reported from Brazil. In this work, we describe two new species of Asclerocheilus Ashworth, 1901. The new species A. geiseae sp. nov. and A. blakei sp. nov. were collected during scientific expeditions to the Espírito Santo and Campos sedementary basins. These expeditions were coordinated by PETROBRAS/CENPES. The species A. geiseae sp. nov. is unique among its congeners by the presence of acicular spines with rounded and curved tips in two rows. The second species, A. blakei sp. nov., differs from its congeners by the combination of the presence of a trapezoidal prostomium, acicular spines on chaetigers 1–3, lyrate chaetae from chaetiger 3 on notopodia and 2 on neuropodia. Moreover, we report the species A. tropicus Blake, 1981 from the localities sampled on this study. We also provide an identification key to all species of Asclerocheilus of the world.
Sipunculans are a poorly studied group in the Tropical Eastern Pacific. For the Southern Mexican Pacific (SMP) there is only one record of a sipunculan species. The main objective of this work was to determine the species composition of the phylum Sipuncula present in the SMP. The study area covered three Mexican states: Guerrero, Oaxaca and Chiapas; specimens from 28 localities were examined from both intertidal and subtidal zones. A total of 551 specimens were reviewed, from which 11 species were identified. Five of them have previously been recorded in the Tropical Eastern Pacific (TEP): Apionsoma (A.) hespera comb. nov., A. (Edmondsius) pectinatum, Aspidosiphon (A.) elegans, Phascolosoma (P.) puntarenae and Themiste (T.) hennahi; four species are similar to nominal species: Sipunculus (S.) cf. polymyotus, Siphonosoma cf. vastum, Siphonosoma cf. cumanense and Phascolosoma (P.) cf. perlucens; and two new species are described: Aspidosiphon (Paraspidosiphon) cutleri sp. nov. and Aspidosiphon (Paraspidosiphon) pastori sp. nov. A checklist and an identification key for all sipunculan species from the TEP are presented. The checklist includes 53 taxa, 25 of which are questionable records. This work generated 11 new records of sipunculans in the SMP and five new records in the TEP.
A taxonomic study on the Afrotropical genera Afrepipona Giordani Soika, 1965 and Afrepsilon gen. nov. is presented. Twenty new species are described, of which 15 are in Afrepipona (Afrepipona anomala sp. nov., Afrepipona cellularis sp. nov., Afrepipona clonata sp. nov., Afrepipona cuprea sp. nov., Afrepipona lamellata sp. nov., Afrepipona lamptula sp. nov., Afrepipona lobulata sp. nov., Afrepipona meridionalis sp. nov., Afrepipona occidentalis sp. nov., Afrepipona orientalis sp. nov., Afrepipona punctatissima sp. nov., Afrepipona scabra sp. nov., Afrepipona segregata sp. nov., Afrepipona ulterior sp. nov., Afrepipona vulcanica sp. nov.) and five are in Afrepsilon (Afrepsilon aterrimum gen. et sp. nov., Afrepsilon ferrugineoaureum gen. et sp. nov., Afrepsilon hybridum gen. et sp. nov., Afrepsilon minor gen. et sp. nov., and Afrepsilon pictum gen. et sp. nov.). Afrepipona lamptoensis Giordani Soika, 1965 is withdrawn from synonymy with A. angusta (de Saussure, 1863) and subsequently revalidated. Afrepipona unifasciata Gusenleitner, 2012 is transferred to the genus Antodynerus de Saussure, 1855 (Antodynerus unifasciatus comb. nov.). Keys to all known species are provided.
Description of four new species of the Neotropical genus Scione Walker, 1850 (Diptera: Tabanidae)
(2024)
After 94 years after the last revision of the genus and after 22 years since the last species was named, we describe four new species of Scione from Ecuador and Peru: S. cooperi sp. nov., S. gertrudeae sp. nov., S. kroeberi sp. nov. and S. merianae sp. nov. We provide diagnoses, descriptions, photographs and discussions for each of the species.
Three Nearctic species of Episyron Schiødte (Hymenoptera: Pompilidae: Pompilinae: Pompilini) were examined morphologically, geographically, and ecologically with intent to infer an aposematic correlation with habitat type, protarsal digging rake morphology, and host spider association. Episyron quinquenotatus quinquenotatus (Say) and E. conterminus cressoni (Dewitz), two subspecies with extensive aposematic markings and more and longer protarsal comb spines, were associated with bare or sparsely vegetated sandy soils near water courses. Episyron biguttatus biguttatus (Fabricus), with few aposematic markings and less and shorter protarsal comb spines, was associated with more densely vegetated terrain and gravelly and loamy soils. Three subspecies of Anoplius apiculatus (Smith) (Hymenoptera: Pompilidae: Pompilinae: Pompilini) are discussed as an aposematic-habitat comparison.

Homocopris Burmeister, 1846 (Coleoptera: Scarabaeidae) is a small genus of South American dung beetles composed of four species distributed in Argentina, Brazil, and Chile. Recently, a neotype was designated for Copris torulosus Eschscholtz, 1822 (currently H. torulosus) based on the assumption that the original type series had been lost. However, this designation is invalid for failing to comply with articles 75.2, 75.3, 75.3.1, and 75.3.4. of the International Code of Zoological Nomenclature. Furthermore, even if it had been nomenclaturally valid, the neotype now loses its type status because we found a syntype in the material of the Johann Friedrich Eschscholtz collection, preserved in the collection of Zoological Museum, Moscow Lomonosov State University, Moscow, Russia. We present evidence supporting the recognition of this specimen as a syntype and newly designate it as the lectotype. Photographs of the lectotype and its labels are provided. Additionally, the geographic distributions of H. punctatissimus (Curtis, 1844) and H. torulosus (Eschscholtz, 1822) in Chile are corrected.

Callidium biguttatum Sallé, 1856 is transferred to Calliclytus Fisher, 1932 new combination. The tribe Callidiini is thus removed from the West Indian fauna. Smodicum miserum Thomson, 1878 is a new synonym of Enosmaeus cubanus Thomson, 1878. Heterops hispaniolae Fisher, 1932 is a new synonym of Eburiola geminata (Fabricius, 1787) and the Dominican Republic is a new country record for the species. Linsleyonides portoricensis (Fisher, 1932) is newly recorded for Hispaniola and the Dominican Republic, new country and island record. Mallosoma bicolor Sallé, 1856 (formerly Trichrous) is transferred to Pseudothonalmus Guerrero in Lingafelter and Micheli, 2004, new combination. Trichrous bicolor Fisher, 1932 (now Trichrous fisheri Monné and Giesbert, 1992 due to homonymy) is a new synonym of Trichrous jaegeri Chevrolat, 1858. Rhopalophora baracoana Zayas, 1975 is transferred to Plectrocerum Dejean, 1835, new combination, and this removes Rhopalophorini from the West Indian fauna. Plectrocerum cribratum Sallé, 1856 is a new synonym of Plectrocerum spinicorne (Olivier, 1800). Plinthocoelium virens (Linnaeus, 1758) is reestablished as the proper name for the West Indian species previously known as Plinthocoelium columbinum (Guérin-Méneville, 1838). The African species called Philematium virens (Linnaeus) should use the senior-most synonym and be called Philematium sansibaricum (Gerstaecker, 1871). Plinthocoelium domingoensis (Fisher, 1922) is a new synonym of Plinthocoelium virens (Linnaeus, 1758). Neoclytus pallidicornis Fisher, 1932 is a new synonym of Neoclytus podagricus White, 1855.

Species lists play an important role in biology and practical domains like conservation, legislation, biosecurity and trade regulation. However, their effective use by non-specialist scientific and societal users is sometimes hindered by disagreements between competing lists. While it is well-known that such disagreements exist, it remains unclear how prevalent they are, what their nature is, and what causes them. In this study, we argue that these questions should be investigated using methods based on taxon concept rather than methods based on Linnaean names, and use such a concept-based method to quantify disagreement about bird classification and investigate its relation to research effort. We found that there was disagreement about 38% of all groups of birds recognized as a species, more than three times as much as indicated by previous measures. Disagreement about the delimitation of bird groups was the most common kind of conflict, outnumbering disagreement about nomenclature and disagreement about rank. While high levels of conflict about rank were associated with lower levels of research effort, this was not the case for conflict about the delimitation of bird groups. This suggests that taxonomic disagreement cannot be resolved simply by increasing research effort.
Thought to be monotypic for decades, the only species in the goosefish genus Lophiomus Gill, Lm. setigerus (Vahl), shows a wide range of morphological variation and is distributed widely in the Indo-West Pacific (IWP). In this study, datasets for two mitochondrial and two nuclear genes sequences obtained from samples of Lophiomus collected in different localities across the IWP were constructed and analyzed to explore the phylogeny and species diversity within the genus. Our integrated approach with multiline evidence unveiled an unanticipated richness of at least six delimited species of Lophiomus. Herein, based on materials already available from museums and new specimens obtained primarily through the Tropical Deep-Sea Benthos program surveying IWP benthic fauna, we formally describe three new species: Lm. immaculioralis sp. nov., Lm. nigriventris sp. nov., and Lm. carusoi sp. nov. Also, we resurrect Lm. laticeps stat. rev. from synonyms of Lm. setigerus. These species can be diagnosed by genetics, body coloration, patterns on the floor of the mouth, peritoneum pigmentation, morphometric measurements, and meristic counts of cranial spines, dorsal-fin spines, and pectoral-fin and pelvic-fin rays from each other and from Lm. setigerus. The species Lm. setigerus, as well as the genus Lophiomus, are re-described accordingly based on the new results. Amended identification keys to the four extant lophiid genera and to species of Lophiomus are also provided.
The Indian species of the genera Orionis Shaw and Stenothremma Shaw (Braconidae, Euphorinae) are reviewed. Both genera are reported for the first time from India. Three new species, Orionis shillongensis Gupta, van Achterberg & Pattar sp. nov. from north-eastern India (Meghalaya), O. femorator Gupta, van Achterberg & Pattar sp. nov. from southern India (Karnataka and Tamil Nadu) and Stenothremma flavator Gupta & van Achterberg sp. nov. from southern India (Karnataka) are illustrated and described. A key to the Old World species of Orionis Shaw is provided.
The family Dendrodorididae has a global distribution, with prevalence in tropical and subtropical intertidal zones. Three species of Dendrodorididae were collected from the intertidal zone of the northern coast of the Persian Gulf in Iran. Based on anatomical, histological, and molecular investigations they can be assigned to Dendrodoris fumata, Dendrodoris nigra, and a new species of Doriopsilla, D. aroni sp. nov. Molecular analyses of CO1 and 16S, including all genera of Dendrodorididae, members of the sister taxon Phyllidiidae, and other dorid outgroups resulted in a polyphyletic genus Dendrodoris, which is in contrast to the nuclear gene studies. Our molecular results confirm the differentiation between Dendrodoris rubra and D. fumata. Dendrodoris nigra, D. fumata, and D. krusensternii each consist of several clades, indicating cryptic species complexes requiring further investigation. We describe the presence of bacteria for the first time in the vestibular gland of D. fumata. Validation of the specimens of Doriopsilla from the Persian Gulf as a new species is supported by haplotype networking, genetic distance, and ABGD analyses of mitochondrial genes. Our CO1 analysis confirms a previous hypothesis that Cariopsilla is a junior synonym of Doriopsilla.
The genus Tekellina Levi, 1957 is currently composed of ten species, six of which are Neotropical. They are small-sized spiders (0.9 to 1.5 mm), with a wide distribution, with a great diversity in the Neotropical Region and well represented in Brazil. In this article, males and females of the species Tekellina bella Marques & Buckup, 1993 and T. crica Marques & Buckup, 1993 are redescribed and illustrated. The female of Tekellina minor Marques & Buckup, 1993 is described and illustrated for the first time. New records are included for Neotropical species. Tekellina guaiba Marques & Buckup, 1993 is synonymized with T. pretiosa Marques & Buckup, 1993. Three new species are described for Brazil: Tekellina picurrucha Rodrigues & Estol sp. nov. (São Paulo, Paraná and Rio Grande do Sul), Tekellina miuda Rodrigues & Estol sp. nov. (São Paulo and Paraná) and Tekellina miudinha Rodrigues & Estol sp. nov. (São Paulo). Distribution maps with new records and an identification key of the Neotropical species are also presented.
Nerillids are small marine annelids, once placed at the artificial group ‘Archiannelida’, which contained all families of the exclusively interstitial polychaetes. Nerillidae is the most species rich family among them, with 71 species grouped into 15 genera, and represents an important component of the interstitial fauna, occupying a wide bathymetric range. Despite its problematic placement among the ‘Archiannelida’ families, the group per se is considered monophyletic. Currently, only two species of Paranerilla are valid, both being reported from the northern hemisphere. It is presented herein as the first description of a species of Paranerilla from tropical waters, named as Paranerilla schiavettii sp. nov., which is also considered as a unique record by the presence of a modified acicular spine in noto- and neuropodia from chaetiger 3–7, not mentioned in its congeners descriptions. Hence, we also propose an emendation on the genus diagnosis to embrace the presence of acicular spines within Paranerilla. So, the presented information complements the current knowledge about the group’s taxonomy and expands its distribution to South Atlantic waters.
In the present study, a revision of the phylogeny and taxonomy of the family Dorididae is carried out focusing on the genus Doris Linnaeus, 1758. The type species D. verrucosa Linnaeus, 1758 and a blueish and yellow morphotype of D. ocelligera collected in different localities in the Mediterranean Sea and the North-East Atlantic were sequenced, as well as D. bertheloti and the elusive D. marmorata for the first time. The genetic markers include the cytochrome c oxidase subunit I, 16S rRNA, and histone 3. The phylogenetic results suggest that the genus Doris is paraphyletic, and D. ocelligera morphotypes separate into two species, as confirmed with species delimitation tests. To complement the phylogenetic evidence with morphoanatomical data, the dissection of two specimens of each morphotype is conducted. Significant differences in morphological traits such as body shape, colouration patterns, and mantle tubercles come to light, together with anatomical differences in the relative shape and size of the radular teeth and reproductive structures. Considering the modern and old descriptions of D. ocelligera, it is finally concluded that the blueish morphotype belongs to D. ocelligera. In contrast, the yellow morphotype responds to the actual synonym Aldisa berghi (Vayssière, 1901), which is resurrected here as Doris berghi comb. rest. Considering the broad phylogeny of the family, some systematic notes at the genus level are here provided.
New World lampyrid taxonomy faces severe taxonomic impediments. Most species remain known from original taxonomic descriptions only, often insufficient for accurate identification. Therefore, the study of type specimens is critical to ensure proper identification. The Russian entomologist Viktor Ivanovich Motschulsky was one of the most important authors of firefly (Coleoptera: Lampyridae) taxonomy during the XIXth century, and his work is still relevant today. Part of his material, including the type specimens of several species, is deposited at the Zoological Institute of the Russian Academy of Sciences. Unlike their European, Asian, and Oceanian counterparts, the taxonomy of Neotropical fireflies is still in its infancy, partly due to largely outdated literature and difficulties in accessing type specimens. Here, we review the type specimens of 38 firefly species deposited at ZIN, 15 of which are holotypes and 7 are lectotypes. For each specimen, the name-bearing status, condition of preservation, as well as the associated label data are provided. Lectotypes are designated for the following species described by Motschulsky: Bicellonycha lividipennis, Ellychnia californica, Lychnuris klugii, Macrolampis longipennis, Pseudolychnuris suturalis, Telephoroides lineaticollis, Telephoroide occidentalis.
Four new species of the genus Catonidia Uhler, 1896, C. triangula sp. nov., C. saccata sp. nov., C. trilobata sp. nov. and C. uncinata sp. nov. from China (Fujian, Guizhou, Yunnan and Hainan provinces), are described and illustrated, giving the genus 14 species in total. A checklist and key to all known species of Catonidia are provided, as well as a map of their geographic distributions.
Phyllanthus novofriburgensis J.C.R.Mendes, J.M.A.Braga & Fraga sp. nov. and P. pedrosae J.C.R.Mendes, J.M.A.Braga & Fraga sp. nov. are new species of Phyllanthaceae described from the Brazilian Atlantic Forest and Brazilian Cerrado, respectively. Phyllanthus novofriburgensis resembles P. acutifolius Poir. ex Spreng., P. hypoleucus Müll.Arg. and P. lilliputianus J.C.R.Mendes, J.M.A.Braga & Fraga, sharing ovate, elliptical, and lanceolate leaf blades. However, it can be distinguished by its pendulous habit, often with sinuous branches and lanceolate leaf blades with characteristically revolute margins. Phyllanthus pedrosae exhibits morphological similarities with P. claussenii Müll.Arg. due to its subshrubby and prostrate habit. It is distinghuished by the unisexual inflorescence with cymules composed of one or two staminate flowers proximally positioned in the axil of the branches and solitary pistillate flowers distally situated, and the 5-merous calyx in the staminate and pistillate flowers. Both new species are classified in Phyllanthus subgen. Phyllanthus sect. Phyllanthus subsect. Clausseniani G.L.Webster, primarily due to the deeply emarginate anthers. Notes on their geographical distribution and habitat are provided, as well as a key to the species of Phyllanthus from Southeastern Brazil.
Four new species of the genus Catonidia Uhler, 1896, C. triangula sp. nov., C. saccata sp. nov., C. trilobata sp. nov. and C. uncinata sp. nov. from China (Fujian, Guizhou, Yunnan and Hainan provinces), are described and illustrated, giving the genus 14 species in total. A checklist and key to all known species of Catonidia are provided, as well as a map of their geographic distributions.

The small, eyeless beetles of the genus Anillinus Casey (Coleoptera: Carabidae: Trechinae: Anillini) comprise a diverse, ubiquitous, but poorly known component of insect biodiversity in the southeastern United States. Their limited dispersal capabilities make them ideal subjects for biogeography, but taxonomic problems and undescribed species diversity hamper such studies. In this paper, we redescribe four enigmatic species, Anillinus docwatsoni Sokolov and Carlton, Anillinus elongatus Jeannel, Anillinus pecki Giachino, and Anillinus turneri Jeannel, and consider their relationships. The elongatus species group is revised, with descriptions of four newly discovered species, Anillinus arenicollis Harden and Caterino, new species, Anillinus montrex Harden and Caterino, new species, Anillinus pittsylvanicus Harden and Caterino, new species, and Anillinus uwharrie Harden and Caterino, new species. Two species previously considered part of the elongatus group are determined to not belong here, Anillinus cavicola Sokolov and Anillinus turneri Jeannel. The exact placement of A. turneri remains uncertain, but it shares some character states with the sinuaticollis group. We erect the pecki group for A. docwatsoni and A. pecki, which are likely sister species. We provide a key to the eastern species groups of Anillinus and the species of the elongatus and pecki species groups. Anillinus pecki is broadly distributed in the southern Appalachian Mountains northeast of the French Broad River basin, while A. docwatsoni is apparently endemic to the Hickory Nut Gorge in western North Carolina. Anillinus pecki is reported for the first time from Tennessee and Virginia. All members of the elongatus group have small geographic ranges and are difficult to sample without special techniques, hinting that many more species await discovery in the densely populated Piedmont region of North Carolina, where natural habitats are rapidly being lost. Our sampling was not dense enough to test biogeographic hypotheses, but distributions of the elongatus group species suggest that hydrochory might have played an important role in passive dispersal and reproductive isolation. These taxonomic contributions will facilitate future studies on the genus and serve to highlight the rich insect biodiversity that remains to be discovered in the southeastern United States.

The Chinese members of the genera Leptothorax Mayr, 1855 and Temnothorax Mayr, 1861 are reviewed based on the morphological characters of the worker caste, and 66 species are recognized in China to date. A new synonym is proposed: T. opaciabdomin (Chang & He, 2001) is a junior synonym of T. mongolicus (Pisarski, 1969). Twenty-eight new species of Temnothorax, T. bailu sp. nov., T. chun sp. nov., T. chunfen sp. nov., T. chushu sp. nov., T. dahan sp. nov., T. dashu sp. nov., T. daxue sp. nov., T. dong sp. nov., T. dongzhi sp. nov., T. guyu sp. nov., T. hanlu sp. nov., T. jingzhe sp. nov., T. lichun sp. nov., T. lidong sp. nov., T. liqiu sp. nov., T. lixia sp. nov., T. mangzhong sp. nov., T. qingming sp. nov., T. qiu sp. nov., T. qiufen sp. nov.,T. shuangjiang sp. nov., T. xia sp. nov., T. xiaohan sp. nov., T. xiaoman sp. nov., T. xiaoshu sp. nov., T. xiaoxue sp. nov., T. xiazhi sp. nov., T. yushui sp. nov., are described from China based on worker caste. Three species of Temnothorax, T. desioi (Menozzi, 1939), T. susamyri (Dlussky, 1965) and T. volgensis (Ruzsky, 1905) are recorded in China for the first time. The following eight species are recorded in a province or autonomous region of China for the first time: Leptothorax acervorum (Fabricius, 1793) is a new record in Qinghai, Sichuan and Yunnan; Temnothorax angulohumerus Zhou et al., 2010 is a new record in Guizhou and Tibet; T. argentipes (Wheeler, 1928) is a new record in Sichuan and Yunnan; T. mongolicus (Pisarski, 1969) is a new record in Inner Mongolia; T. reticulatus (Chang & He, 2001) is a new record in Beijing, Gansu, Inner Mongolia, Jilin, Shaanxi and Yunnan; T. spinosior (Forel, 1901) is a new record in Yunnan; T. taivanensis (Wheeler, 1929) is a new record in Guizhou, Sichuan and Yunnan; and T. zhejiangensis Zhou et al., 2010 is a new record in Henan and Guangxi. A key based on the worker caste is provided for the 66 known Chinese species.
As insect decline threatens the fauna of Central Europe, “dark taxa” present an obstacle to understanding biodiversity loss. The superfamily Platygastroidea is a dark taxon, with many superficial descriptions requiring examination of type material to characterize and revise species and genera. The Natural History Museum Vienna (Naturhistorisches Museum Wien) is arguably the most important historical collection of Platygastroidea in Central Europe. Type specimens from 85 species in 21 genera and three families are here catalogued and photographically illustrated, including previously undocumented types described by Förster, Kieffer, Nees von Esenbeck, and Ratzeburg. Lectotypes are designated for Anteris bicolor Kieffer, Anteris simulans Kieffer, Hadronotus laticeps Kieffer, Leptacis foersteri Kieffer, Plastogryon investis Kieffer, Plastogryon sagax Kieffer, Prophanurus mayri Kieffer, and Telenomus laeviceps Förster. Trissolcus schimitsheki (Szelényi) syn. nov. is treated as a junior synonym of Trissolcus scutellaris (Thomson) and Telenomus nomas Förster syn. nov. is treated as a junior synonym of Trissolcus semistriatus (Nees). Baeus maculatus (Förster) comb. nov. is transferred from Telenomus. Historical, taxonomic, and curatorial remarks are included, providing an essential foundation for revisionary work on the Platygastroidea of Central Europe and beyond.
Rove beetles (Staphylinidae) are a diverse insect group, especially in the Neotropical region. At the same time, this fauna remains significantly understudied. During our visits to museum collections, we encountered numerous specimens of undescribed species representing the Neotropical genus Neolindus Scheerpeltz, 1933 which was earlier thought to be rare. To address the knowledge gap in the genus, we studied the museum material that resulted in descriptions of 21 new species. Our work involves the redescription of the genus, descriptions of the new species, and an updated identification key to 39 previously described and new species. The newly described species are Neolindus bicornis Guzman, Tokareva & Żyła sp. nov., N. elegans Guzman, Tokareva & Żyła sp. nov., N. longithorax Guzman, Tokareva & Żyła sp. nov., N. luxipenis Guzman, Tokareva & Żyła sp. nov., N. maya Guzman, Tokareva & Żyła sp. nov., N. minutus Guzman, Tokareva & Żyła sp. nov., N. napo Guzman, Tokareva & Żyła sp. nov., N. niger Guzman, Tokareva & Żyła sp. nov., N. ornatus Guzman, Tokareva & Żyła sp. nov., N. parahermani Guzman, Tokareva & Żyła sp. nov., N. paraplectrus Guzman, Tokareva & Żyła sp. nov., N. parasinuatus Guzman, Tokareva & Żyła sp. nov., N. parautriensis Guzman, Tokareva & Żyła sp. nov., N. pseudosensillaris Guzman, Tokareva & Żyła sp. nov., N. sauron Guzman, Tokareva & Żyła sp. nov., N. sibyllae Guzman, Tokareva & Żyła sp. nov., N. triangularis Guzman, Tokareva & Żyła sp. nov., N. tropicalis Guzman, Tokareva & Żyła sp. nov., N. utriensis Guzman, Tokareva & Żyła sp. nov., N. volkeri Guzman, Tokareva & Żyła sp. nov., and N. yotokae Guzman, Tokareva & Żyła sp. nov. This research emphasises the importance of museum collections in advancing taxonomy and enriching biodiversity knowledge. With these contributions, the known number of species of Neolindus reaches 60, thereby enhancing data on the Neotropical rove beetles diversity. Additionally, we provide several new country records for the genus (Guyana, Mexico, Nicaragua, and Suriname), which widen its distribution, and new occurrence records for the described species of Neolindus, N. agilis Herman, 1991; N. apiculus Herman, 1991; N. basisinuatus Herman, 1991; N. campbelli Herman, 1991; N. cuneatus Herman, 1991; N. hermani Asenjo, 2011; N. irmleri Asenjo, 2011; N. lodhii Herman, 1991; N. procarinatus Herman, 1991; N. punctogularis Herman, 1991; and N. retusus Herman, 1991.
The fossil record of the diverse subfamily Passifloroideae (>750 species and 17 genera) is relatively poor. Despite the distinctiveness of its leaves (glandular and often emarginate), most of the fossils from this group have been described from seeds. Fossil seeds have been recovered from Europe, and North and South America. A lack of information on seed morphology for all the genera and tribes of this subfamily has prevented a tribe-level identification of the fossils and a better understanding of their biogeographic patterns. The Passifloroideae is divided into three tribes: Passifloreae with 10 genera, Paropsieae with six genera and the monotypic Jongkindieae. This study provides new descriptions for 15 species from 5 genera from the mostly Afrotropical tribe Paropsieae based on herbarium material, and introduces an online seed database and a key for 100 species of Passifloroideae compiled from literature and direct observations. Our study shows a low morphological diversity among the seeds of Paropsieae in comparison to a much larger diversity within Passifloreae. Some rare morphologies are only present in Passifloreae and can be used to assign seeds to this tribe. Within the Paropsieae, Androsiphonia has seed that are very distinct from those in the other genera in the tribe and also from the rest of the subfamily. The genus Paropsia exhibits two main morphotypes, while the genera Barteria, Paropsiopsis and Smeathmannia have very similar seeds with a highly conserved morphology. These results suggest that living or fossil Paropsieae cannot be identified confidently based solely on seed characters.
Four new species of the Australian genus of Eurybrachidae (Hemiptera, Fulgoromorpha) Olonia Stål, 1862 are described from northern Queensland: O. albomarginata sp. nov., O. aschei sp. nov., O. jackiei sp. nov. and O. lindae sp. nov. Host plants and natural history data are documented and additional new records provided for O. guillaumei Constant, 2018, O. hochae Constant, 2018, O. picea Kirkaldy, 1906, O. rubicunda (Walker, 1851) and O. soulierae Constant, 2018. Trophobiosis is recorded for the first time in the genus, between a female of O. hochae and ants of the genus Camponotus Mayr, 1861 (Hymenoptera, Formicidae), representing the second record of trophobiosis in Australian Eurybrachidae. The male terminalia of the new species are illustrated and photographs of collection and live specimens, distribution maps, biological data and an identification key are provided. The genus Olonia currently contains sixteen species.
Twenty-one species of Mysidae were sampled by three ANDEEP expeditions to the Southern Ocean with epibenthic sledges dragged over the deep-sea floor in the realm of 58–71° S and 00–65° W, depth 774–5190 m. Previously known ranges are significantly extended southward for four species and to greater depth in the same four species plus two other species. Supplementary descriptions are given for Amblyops tattersalli and Dactylamblyops murrayi, and a first description of a (subadult) male for Thalassomysis tattersalli. The definitions of the genera Amphiakrops gen. nov., Chelamblyops gen. nov., Desmocornea gen. nov. and Schizurakrops gen. nov. are mainly based on the structure of the eyes as well as of the antennal peduncle, chelate second thoracic endopod and telson. These structures are also important for the descriptions of Amblyops arianii sp. nov., A. bipapillatus sp. nov., Amblyopsoides fenestragothica sp. nov., A. lepidophthalma sp. nov., Amphiakrops brandtae gen. et sp. nov., Dactylamblyops benthophilus sp. nov., Desmocornea subchelata gen. et sp. nov., Paramblyops petrescui sp. nov., Schizurakrops meesi gen. et sp. nov., Scolamblyops muehlenhardtae sp. nov., Stellamblyops doryphorus sp. nov. and Mysidella antarctica sp. nov. Six previously described taxa are recombined as Amblyopsoides laticauda comb. nov., Amphiakrops bidigitatus comb. nov., A. japonicus comb. nov., Chelamblyops globorostris comb. nov., Meierythrops tattersalli comb. nov. and M. triangulatus comb. nov. One species is revised back to the initial combination as Dactylamblyops japonicus. All except one (Mysidella antarctica sp. nov.) newly described (12), newly recombined (6) or back-combined (1) species belong to the Erythropinae. Keys to the resulting 61 genera and 263 species of Erythropinae and 18 species of Mysidellinae are given at the world-wide scale. Ocular papillae with a terminal pore (sensory pore organ) are recorded in nine ANDEEP species. The organ of Bellonci is identified on the reduced eyes in 16 species, among which D. subchelata gen. et sp. nov. has many ommatidia arranged in a self-contained ribbon which shows a banded rhabdom only in non-adults. Reduction of visual elements together with shrinking of ocular papillae during ontogenetic development suggest that non-adults of D. subchelata and T. tattersalli stay in the photic zone for feeding and growth and then descend only once during their lifetime to the abyss for reproduction.
Until now, the genus Porcelliniodes Miers, 1877 is represented in the Ibero-Balearic region by seven species. The study of 721 specimens from Portugal and Spain has led to the identification of 11 species, including poorly known species, and the description of a new species, Porcellionides ibericus sp. nov. This new species is characterized by the absence of transverse ridges on the pereonites, medium-sized lateral lobes on the cephalon, the pleon slightly retracted in relation to the pereon, pereopods without sexual differentiation, and a truncated posterior inner tip in the male pleopod I. We consider P. glaber (Koch, 1856), P. hispanus (Vandel, 1953), P. lucasioides (Vandel, 1953), P. lusitanus (Vandel, 1946), and P. molleri (Verhoeff, 1901) as valid species, while P. buddelundi (Verhoeff, 1901) and P. rufocinctus (Dollfus, 1892) are considered species inquirendae. Five species are recorded for the first time in some Portuguese districts and seven in some Spanish provinces.
Research on the Heteroptera fauna of Turkey has not been extensive enough to illustrate its true diversity. Although several factors contribute to this, the lack of an up-to-date and comprehensive review is a basic factor. To address this issue, we compiled a list of all the Heteroptera species recorded from Turkey in the literature and iNaturalist. In addition, we re-examined several specimens preserved in the Lodos Entomological Museum, İzmir, Turkey (LEMT). Consequently, we excluded 24 species from the checklist of Heteroptera fauna of Turkey, and proposed a new synonymy: Psallus (Psallus) pardalis Seidenstücker, 1966 = Psallus (Psallus) oenderi Wagner, 1976 syn. nov. Furthermore, we recorded following six species from Turkey for the first time: Blissus hirtulus Burmeister, 1835 (Blissidae), Loricula (Loricula) pselaphiformis Curtis, 1833 (Microphysidae), Globiceps (Globiceps) coryli V.G. Putshkov, 1970, Heterocordylus (Heterocordylus) cytisi Josifov, 1958, Mesopsallus fagi (Drapolyuk, 1990) and Psallus (Psallus) helenae Josifov, 1969 (Miridae); and described following six species as new for science: Orthonotus efei Çerçi & Koçak sp. nov., Orthotylus (Parapachylops) oenderi Çerçi, Tezcan & Koçak sp. nov., Orthotylus (Pinocapsus) girayi Çerçi & Tezcan sp. nov., Psallus (Psallus) eceae Çerçi & Koçak sp. nov., Psallus (Psallus) pehlivani Çerçi & Tezcan sp. nov. and Ribautocapsus tezcani Çerçi sp. nov. Altogether, 1668 species of Heteroptera have been recorded from Turkey (664 species in the European part and 1633 species in the Anatolian part) until now, out of them, the presence of 37 species needs confirmation. We determined the chorotypical composition of species as follows: Mediterranean (399 spp., 23.9%), European (380 spp., 22.8%), Local (280 spp., 16.8%), Widespread (182 spp., 10.9%), Endemic (128 spp., 7.7%), Turanian (127 spp., 7.5%), Turano-Mediterranean (89 spp., 5.3%), Europeo-Mediterranean (68 spp., 4.1%) and Alien (12 spp., 0.7%). We showed that provinces in the Eastern Anatolian, Southeastern Anatolian, and Black Sea regions had lower numbers of species recorded, compared to the provinces in the remaining regions. Finally, we underlined that 109 species, absent from Turkey, were recorded from three or more neighboring countries of Turkey. In summary, our findings emphasize that despite the abundant research devoted over the last 150 years to the Heteroptera fauna of Turkey, our understanding of it remains incomplete in the majority, if not in all, of the regions. Our findings strongly encourage further research, particularly in regions with small numbers of recorded species. This endeavor will undoubtedly lead to numerous novel discoveries and provide a better understanding of the true Heteroptera diversity in Turkey.
