Hentschke gen. nov. (based on LEGE 16533 and LEGE 16651) and Leptolyngbyopsis G.S. Hentschke gen. nov. (based on LEGE 16524). These strains were sampled from freshwater environments at Figueira da Foz, Monchique and Coimbra, Portugal. Both genera are morphologically and ecologically identical to Leptolyngbya and can only be distinguished from it by molecular analyses. Based on morphological and ITS secondary structure analyses we describe two species of Pseudoleptolyngbya, P. figueirensis and P. monchiquensis. P. figueirensis differs from P. monchiquensis by the denser arrangement of the trichomes, the presence of firm sheaths, the common formation of shorter trichomes (up to 30 cells), and the olive or yellowish-green cell content, which is darker in P. monchiquensis. Moreover, the macroscopic appearance of P. figueirensis is a dense brownish mat, while P. monchiquensis is less dense and reddish. 16S rRNA gene sequences of Arthronema africanum CCALA020 are > 99% identical to Leptolyngbya boryana PCC6306, so we transfer A. africanum to Leptolyngbya, as L. africanoidea. Pseudoleptolyngbya gen. nov. and Leptolyngbyopsis gen. nov. are described.Arthronema is placed in synonymy with Leptolyngbya.Pseudoleptolyngbya gen. nov. and Leptolyngbyopsis gen. nov. are described.Arthronema is placed in synonymy with Leptolyngbya.

Jumping spiders (Salticidae) are a diverse group of non‐web‐building predators and the most species‐rich spider family. The Salticidae Tribe Nannenini consists of a small group of Oriental jumping spiders that are very poorly known. The use of explicit phylogenetic analyses to establish its affinities has so far remained limited. The Nannenini genus Epidelaxia has a peculiar morphology, making its systematic position uncertain. In this study, we present a comprehensive dataset combining molecular and morphological data for Nannenini, including exemplars from all genera. This dataset comprises DNA sequences of approximately 2400 bp, including nuclear genes (18S, 28S and H3) and the mitochondrial gene CO1, sequenced for 40 taxa (20 ingroups and 20 outgroups), along with 61 morphological characters. Notably, both DNA sequences and morphological traits were analysed separately and concurrently for the first time. The Nannenini clade is recovered with high support. Further, Epidelaxia is monophyletic and sister to Tubalaxia gen. n. This is the first hypothesis on the internal phylogenetic structure of Epidelaxia and its placement within the Tribe Nannenini. A new genus Tubalaxia gen. n. and the following new species are described: E. bharathi sp. n., E. somasundaram sp. n., T. castanea sp. n., T. aurea sp. n. The following new combination is proposed: Tubalaxia minuta (Prószyński, 1992) comb. n. Epidelaxia albostellata, E. albocruciata and E. obscura are redescribed. It is worth noting that the newly described species face endangerment due to their limited distribution and small population sizes. [ABSTRACT FROM AUTHOR]

Killifishes (Cyprinodontiformes) are a group of fish that include a high proportion of small-bodied species living in seasonal aquatic habitats, with narrow geographical distributions and high human impact. They are among the most vulnerable vertebrates in the Neotropical region, with nearly half of the species in threat categories. Herein, we propose a new phylogenetic hypothesis of the Rivulidae genus Austrolebias , based on 10 genes (six nuclear and four mitochondrial) and 191 morphological characters, including 90% of the total valid species of this genus. An updated definition and diagnosis of the existing subgenera of Austrolebias is provided, and these are erected to genera. Also, four new genera are erected to accommodate the taxonomy of the group to the current phylogenetic hypothesis. Additionally, we describe Argolebias guarani sp. nov. , from a seasonal pond in the Middle Paraná River basin, which is diagnosed by a unique colour pattern. This addition reinforces this area as a biodiversity hotspot of endemicity and highlights the importance of this region for conservation. Data on the ontogenetic changes in colour pattern, chorion ornamentation of the egg and ecology of this species are also provided. [ABSTRACT FROM AUTHOR]

Two new genera of pygmy grasshoppers belonging to the subfamily Batrachideinae (Orthoptera: Tetrigidae) are described from Central America, each including a single new flightless species. Naskreckiana kosemeni Kasalo, Buzzetti & Skejo gen. & sp. nov. is described from Costa Rica, Procellator kai Kasalo, Skejo & Cambra gen. & sp. nov. is described from Panama. Facts suggesting that †Eotetrix Gorochov, 2012, stat. restit., is not a synonym of Tettigidea Scudder, 1862 are discussed. The dichotomous key to Batrachideini by SILVA et al. (2021) is updated with the inclusion of these two new genera. Currently, the tribe Batrachideini includes 14 extant genera and 61 extant species. [ABSTRACT FROM AUTHOR]

Two new genera and one new species of the Braconinae tribe Adeshini are described and illustrated: Crenuladesha Ranjith & Quicke, gen. nov., type species Adesha narendrani Ranjith, 2017, comb. nov. from India, and Protadesha Quicke & Butcher, gen. nov., type species Protadesha intermedia Quicke & Butcher, sp. nov. from South Africa. The former lacks the mid-longitudinal propodeal carina characteristic of the tribe, and the latter displays less derived fore wing venation with two distinct abscissae of vein 2CU. A molecular phylogenetic analysis is included to confirm their correct placement. Since neither of the two new genera displays all of the characters given in the original diagnosis of the Adeshini a revised diagnosis is provided, as well as an illustrated key to the genera.

Liassodites obsti gen. et sp. nov., an Early Jurassic member of Trachypachidae, is described from Western Pomerania (Germany). An epoxy resin transfer method is applied for the preparation of three-dimensionally preserved fossil. An annotated list of Palaeozoic and Mesozoic trachypachid genera was elaborated. For each trachypachid fossil member and erroneously placed genus, a short diagnosis or available arguments on systematic position are proposed. The relations of the subfamilies Eodromeinae and Coptoclaviscinae (Coptoclavidae) are discussed. The description of Liassodites obsti gen. et sp. nov. makes it possible to suppose that the currently recognised hiatus between families Carabidae and Trachypachidae is not great enough to regard them as two separate families. The genus Coptoclavisca should be regarded as a member of Trachypachidae or Carabidae (including Trachypachinae). The new genus Apermunda gen. nov. is proposed for Petrodromeus minor. Novunda nom. nov. is proposed for Unda and the following binominal names are changed: Novunda angulata comb. nov., N. cursoria comb. nov., N. microplata comb. nov., N. pachycephala comb. nov. and N. chifengensis comb. nov. A synonymy of Evertus and Fortiseode is established, with change of species name: Evertus pervalimand comb. nov. The taxa Beipiaocarabus, Leptopodocoleus (including Leptopodocoleidae), Praedodromeus, Procalosoma, Xinbinia, 'Eodromeus' viriosus, 'Unda' chonggezhuangensis and 'Unda' pandurata, 'Karadromeus' xiangfanggouensis are regarded as incertae sedis.

The family Cerasommatidiidae was proposed by Brèthes in 1925 for his new genus Cerasommatidia from Brazil, described as an intermediate taxon between Endomychidae and Coccinellidae (Coccinelloidea). This group was neglected for decades until 1994 when the resemblance of Cerasommatidia with the eupsilobiine genus Ibicarella was noticed, and Cerasommatidiidae was synonymized with Eupsilobiinae (Endomychidae). Based on the newly discovered material from the Neotropical and Afrotropical regions with clear resemblance to Cerasommatidia and Ibicarella , the phylogenetic placement of these taxa and new allied genera was reassessed based on phylogenetic analyses of molecular, morphological and combined datasets. The data were analysed under Bayesian (BI), maximum likelihood (ML) and parsimony (MP) frameworks. Our results support the restoration of Cerasommatidiidae as a distinct family in Coccinelloidea. Close affinity of Cerasommatidiidae with Coccinellidae, Eupsilobiidae and Mycetaeidae is recovered and the sister-relationship to Mycetaeidae is highly supported. Ibicarella is found to be a junior synonym of Cerasommatidia. Three new genera and six new species are described and illustrated: Yamuy gen. nov. (type species, Y. marginatus sp. nov. ; and Y. constratus sp. nov.) and Karumbe gen. nov. (type species, K. geiseri sp. nov. ; K. brethesi sp. nov. and K. pakaluki sp. nov.) from the Neotropics and Mahavelo gen. nov. (type species, M. madagasus sp. nov.) from Madagascar.

Two rare species of the genera Chamaemyces and Hodophilus, Chamaemyces fracidus and Hodophilus tenuicystidiatus, are described as new records from Aegean part of Turkey. The phylogenetic placement of C. fracidus and H. tenuicystidiatus are investigated based on multi‐gene molecular analyses containing nrITS and nrLSU data sets. Results indicate that collections for the two species formed separate lineages in the Chamaemyces and Hodophilus clades respectively. Detailed description of the morphological characters, line drawings of micromorphological features, color photographs, ecological preferences are provided and species delimitation are supported with phylogenetic analyses.

Six species from New Guinea which previously were placed in the genus Tigrioides Butler, 1877 are transferred to five genera of which four new to science: Chionatosia gen. nov., Parapelosia Bethune-Baker, 1908, Lithopelosia gen. nov., Blavipelosia gen. nov. and Eugopelosia gen. nov. Nine species have been discovered new to science: Blavipelosia tenebris spec. nov., B. staatsi spec. nov., B. habbemaensis spec. nov., B. armata spec. nov., Eugopelosia gaedei spec. nov., E. obscura spec. nov., E. transnovaguinea spec. nov., E. milnensis spec. nov. and E. nana spec. nov. Tigrioides costaepunctata f. inversa Gaede, 1925 is an infraspecific and therefore invalid name for what appears to be a new species: Eugopelosia gaedei spec. nov.

Vespertilionidae (class Mammalia) constitutes the largest family of bats, with ~500 described species. Nonetheless, the systematic relationships within this family are poorly known, especially among the pipistrelle-like bats of the tribes Vespertilionini and Pipistrellini. Perhaps as a result of their drab pelage and lack of obvious morphological characters, the genus and species limits of pipistrelle-like bats remain poorly resolved, particularly in Africa, where more than one-fifth of all vesper bat species occur. Further exacerbating the problem is the accelerating description of new species within these groups. In this study, we attempt to resolve the systematic relationships among the pipistrelle-like bats of sub-Saharan Africa and Madagascar and provide a more stable framework for future systematic efforts. Our systematic inferences are based on extensive genetic and morphological sampling of > 400 individuals covering all named genera and the majority of described African pipistrelle-like bat species, focusing on previously unstudied samples of East African bats. Our study corroborates previous work by identifying three African genera in Pipistrellini (Pipistrellus , Scotoecus and Vansonia), none of which is endemic to Africa. However, the situation is more complex in Vespertilionini. With broad taxonomic sampling, we confirm that the genus Neoromicia is paraphyletic, a situation that we resolve by assigning the species of Neoromicia to four genera. Neoromicia is here restricted to Neoromicia zuluensis and allied taxa. Some erstwhile Neoromicia species are transferred into an expanded Laephotis , which now includes both long-eared and short-eared forms. We also erect two new genera, one comprising a group of mostly forest-associated species (many of which have white wings) and the other for the genetically and morphologically unique banana bat. All four of these genera, as recognized here, are genetically distinct, have distinctive bacular morphologies and can be grouped by cranial morphometrics. We also demonstrate that the genus Nycticeinops , until now considered monospecific, includes both Afropipistrellus and the recently named Parahypsugo , thus representing the fifth African genus in Vespertilionini. A sixth genus, Hypsugo , is mostly extra-limital to sub-Saharan Africa. Finally, we describe three new species of pipistrelle-like bats from Kenya and Uganda, uncovered during the course of systematic bat surveys in the region. Such surveys are greatly needed across tropical Africa to uncover further bat diversity. [ABSTRACT FROM AUTHOR]

Orthotheres Sakai, 1969, was recently restricted to three species from the western Pacific, noting that other species assigned to this genus from the Americas, Philippines and Palau belonged to other genera. Studies of the non-Orthotheres material confirm that the species from the Americas should be placed in a new genus, Mesotheres, characterised by the structure of the carapace, eyes, third maxilliped and ambulatory legs. Mesotheres includes Pinnotheres barbatus Desbonne, in Desbonne & Schramm, 1867, Pinnotheres serrei Rathbun, 1909, Pinnotheres strombi Rathbun, 1905, and Fabia unguifalcula Glassell, 1936. Three species from the western Pacific, Pinnotheres glaber Bürger, 1895, Pinnotheres laevis Bürger, 1895, and Pinnotheres longipes Bürger, 1895, are referred to a new genus, Tacitotheres, and can be distinguished by carapace form, as well as structure of the third maxilliped and ambulatory legs.

Podostemaceae, the river-weeds, are characterized by remarkable differences between species and genera, which resulted from saltational evolution. This paper presents additional cases of such two genera, which are described here from the Phou Khao Khouay National Protected Area in northern Central Laos. Molecular phylogenetic data show that Ctenobryum mangkonense (gen. & sp. nov.) is sister to Hydrodiscus koyamae, while Laosia ramosa (gen. & sp. nov.) is isolated from all Asian genera of subfamily Podostemoideae. Ctenobryum mangkonense is distinct from Hydrodiscus koyamae in the crustose roots (versus rootless in the latter), scattered flowers on the root (versus alternate on the shoot), and pectinate bracts (versus simple, sheath-like). Laosia ramosa is distinct from all the genera in the columnar, endogenously branched axes and single style-stigma complex. The axis is an enigmatic organ with combined characteristics of root, stem and leaf, pending further study. Laos, together with Thailand, is a center of diversity of the Southeast and East Asian Podostemoideae. The three monotypic genera, i.e., Ctenobryum, Hydrodiscus and Laosia, occur in neighboring and closely similar aquatic habitats within the Area. The new taxa are formally described.

Three new acotylean polyclads are described from the littoral zone in Queensland. Amyris bulbosa sp. nov. (Notoplanidae Faubel, 1983) is distinguished from congeners in possessing a prominent vagina bulbosa. Emprosthopharynx heroniensis sp. nov. (Stylochoplanidae Faubel, 1983) differs from related species in lacking sub-marginal eyes and tentacles, in the anterior position of the cerebral eyes, and possessing few ruffles in the pharynx and uterine vesicles. Zygantrella queenslandensis gen. nov., sp. nov. is erected as a monotypic genus within the Ilyplanidae Faubel, 1983 differing from confamilial genera in lacking a prostate but possessing a common gonopore and a penis stylet.

This study reviews the Gyrocochlea-grade charopid snails of mid-eastern Queensland. Gyrocochlea auct., characterised by brown, biconcave shells with a diameter of 3-7 mm, has been shown to be polyphyletic (Shea et al. 2010). Gyrocochlea s.s. is confirmed as a genus geographically restricted to the Border Ranges of south-east Queensland and north-eastern New South Wales (Stanisic 1990). This study utilised scanning electron microscopy of the shell architecture, qualitative and quantitative measurements of conchological features and anatomical dissection where suitable specimens were obtainable. Based on shell morphology, primarily protoconch sculptural patterns (as defined in Holcroft 2018), this study re-assigns three Gyrocochlea-grade species, G. chambersae (Stanisic, 2010), G. iuloidea (Forbes, 1851) and G. danieli (Stanisic, 2010) to three new genera, Stanisicaropa gen. nov., Whitcochlea gen.nov. and Radiolaropa gen.nov. respectively and diagnoses four new genera, Amfractaropa gen.nov., Comularopa gen.nov., Nodularopa gen. nov. and Xenoropa gen.nov. Five new species are described: Nodularopa samanthae sp. nov., Amfractaropa bretti sp. nov., Comularopa georginae sp. nov., Radiolaropa eungella sp. nov., and Xenoropa wigtonensis sp. nov.

Proarescon Huber, gen. n., is described for P. primitivum (Huber), comb. n., transferred from Borneomymar Huber, and P. similis Huber, sp. n., from Thailand. The previously unknown male of Borneomymar madagascar Huber is described and the genus is redescribed from critical point dried and slide mounted specimens. Triadomerini, stat. n., is proposed to include six genera: Borneomymar, Eustochomorpha and Neotriadomerus, and the Cretaceous Carpenteriana Yoshimoto, Macalpinia Yoshimoto and Triadomerus Yoshimoto. Aresconini is proposed to include five (possibly six) genera: Arescon Enock, Kikiki Huber and Beardsley, Proarescon Huber and Tinkerbella Huber and Noyes, and the Cretaceous Myanmymar Huber and, tentatively, also Enneagmus Yoshimoto. The two tribes are proposed as being the earliest lineages in Mymaridae, with Neotriadomerus and Triadomerus being sister genera to the remaining extant and extinct genera, respectively.

This paper reports for the first time two new genera (Austrothoe and Paranexes) and four new species (Austrothoe jimlowryi-type species, A. ochos, Paranexes gallaharae, and P. yallingup-type species) of Ampithoidae (Amphipoda). The two new genera (and all four species) have only been recorded from southern Australian waters, in particular, off the coasts of southern WA, VIC, and NSW. Austrothoe can be distinguished from other ampithoid genera by having a denticulated, subrectangular telson and strongly prehensile, almost subchelate pereiopods 6 and 7. Paranexes is distinguished from other ampithoid genera by having the epistome and upper lip directed backwards, and no lateral, distal peduncular projection on the male first uropod. An updated key to the genera of Ampithoidae is also provided, as well as keys to the species within each of the new genera. [ABSTRACT FROM AUTHOR]

The tribe Scolopini is characterized by having males with uradenia consisting of paired glands with either a single or paired openings on abdominal sternum III or IV (exceptionally on V), and females with copulatory tubes (not in Calliodina), and by a midventral abdominal copulatory site.

Two new genera and five new species of feather mites of the family Proctophyllodidae are described from passerine birds from Brazil: Tyranniphyllodes pitangi gen. n., sp. n. from Pitangus sulphuratus (Tyrannidae); Atrichophyllodes delalandi gen. n., sp. n. from Corythopis delalandi (Tyrannidae); A. mentalis gen. n., sp. n. from Dysithamnus mentalis (Thamnophilidae); Anisophyllodes candango sp. n. from Elaenia chiriquensis (Tyrannidae); and Platyacarus sittasomi sp. n. from Sittasomus griseicapillus (Dendrocolaptidae). The discovery of these taxa might give data for a better understanding of the evolution of the family Proctophyllodidae in general and the dispersion of these mites on passerines in South America in paricular.

Two new genera and species of the stygobiont gammaridean amphipod family Bogidiellidae are described from anchialine or fully marine subterranean habitats in Mediterranean and SW Pacific Islands. Fidelidiella pectinata, from a littoral cave in Lifou (Loyalty Islands), differs from any other bogidiellid known thus far by the presence on the left mandible of a modified lacinia which is hypertrophied and expanded laterally, and by the possession of a transverse row of strong rounded processes on the anterior side of the distomedial corner of the fourth segment of the maxillipedal palp. This is the most easterly record of bogidiellid amphipods in the SW Pacific. Racovella uniramea, discovered in a Mallorcan anchialine cave, is remarkable among the Bogidiellidae in exhibiting a combination of only six distal spines on the basal endite of the maxillule, and presence of coxal gills on pereopods 3-6. We place particular emphasis on the determination of segmental homologies of all limbs and on the resolution of fine-scale integumentary details, in order to provide a sound basis for future comparison with other family members.

Three species of scale‐worms inhabiting chaetopterid tubes have been found during routine studies of benthic communities. Anotochaetonoe michelbhaudi gen. and sp. nov. occurred in the East Atlantic off Congo in association with Spiochaetopterus sp. and Phyllochaetopterus sp. It has a relatively short body (fewer than 50 segments); elytra in posterior part of the body arranged on chaetigers 23, 26, 29, 32, 34, 37, 40, 43, 46, present to posterior end; achaetous notopodia; neuropodia long, with longer subtriangular prechaetal lobes and shorter postchaetal lobes rounded distally; upper neurochaetae unidentate and lower bidentate; globular ciliated papillae present between ventral cirri and ventral basis of neuropodia. Lepidasthenia brunnea occurred in the Mediterranean Sea off the French coast both free‐living and in association with Phyllochaetopterus sp. Ophthalmonoe pettiboneae was found in Vietnam (South China Sea) in association with Chaetopterus sp. This is the second finding of the species. The characteristics of the associations between chaetopterid genera and symbiotic polychaetes are discussed. [ABSTRACT FROM AUTHOR]
