Mollusca is the second-largest animal phylum with over 100,000 species among eight distinct taxonomic classes. Across 1000 living species in the class Polyplacophora, chitons have a relatively constrained morphology but with some notable deviations. Several genera possess “shell eyes”, true eyes with a lens and retina that are embedded within the dorsal shells, which represent the most recent evolution of animal eyes. The phylogeny of major chiton clades is mostly well established, in a set of superfamily and higher-level taxa supported by various approaches including multiple gene markers, mitogenome-phylogeny and phylotranscritomic approaches as well as morphological studies. However, one critical lineage has remained unclear: Schizochiton was controversially suggested as a potential independent origin of chiton shell eyes. Here, with the draft genome sequencing of Schizochiton incisus (superfamily Schizochitonoidea) plus assembly of transcriptome data from other polyplacophorans, we present phylogenetic reconstructions using both mitochondrial genomes and phylogenomic approaches with multiple methods. Phylogenetic trees from mitogenomic data are inconsistent, reflecting larger scale confounding factors in molluscan mitogenomes. A consistent robust topology was generated with protein coding genes using different models and methods. Our results support Schizochitonoidea is a sister group to other Chitonoidea in Chitonina, in agreement with established classification. This suggests that the earliest origin of shell eyes is in Schizochitonoidea, which were also gained secondarily in other genera in Chitonoidea. Our results have generated a holistic review of the internal relationship within Polyplacophora, and a better understanding on the evolution of Polyplacophora.
Two new species of aulacid wasps, Pristaulacus iuliae Turrisi & Nobile sp. nov. from South India (Karnataka) and Pristaulacus ninae sp. nov. from Peninsular Malaysia (Pahang), are described, figured and compared with most related species. Based on the present addition, the Indomalayan area currently includes 27 species of Pristaulacus Kieffer out of 61 known from the whole Oriental Region, which is however a largely underestimated number. An identification key to species and an updated checklist of Pristaulacus occurring in the Indomalayan area are provided.
The enigmatic ‘y-larvae’ (Thecostraca: Facetotecta) are microscopic marine planktonic crustaceans that were discovered more than a century ago, yet to this day their adults remain unknown. Despite occurring locally in large diversities, and therefore presumably being of ecological importance, only 17 species have been described globally, rendering it practically impossible to identify any y-larval specimen from any locality. The fact that species have been based on different life stages (nauplii and/or cyprids) further hampers identification. Y-larvae include many forms with planktotrophic (feeding) nauplii and even more with lecithotrophic (non-feeding) nauplii. At one coral-reef locality on the shore of Sesoko Island (Okinawa, Japan), extensive fieldwork in 2018 and 2019 confirmed an enormous taxonomic diversity of y-larvae there. Here, we present morphological diagnoses and an identification key for 34 lecithotrophic y-naupliar types (or morphospecies), which will correspond minimally to the same number of species when described. As a temporary measure, all are referred to by alphabetical parataxonomic designations, except for three that have been formally described already within the genus Hansenocaris Itô, 1985. To this should be added an additional 7–9 planktotrophic y-naupliar morphospecies, which are only treated briefly. Most often, y-larval taxonomy has been based on the cyprid stage, but the large morphological diversity of y-nauplii suggests that nauplii are at least as important for taxonomy. Lecithotrophic y-nauplii display a multitude of body shapes, the form-evolution of which is discussed here with reference to a recent molecular phylogeny of Facetotecta partly based on material from the same site. An indirect estimate of the relative abundances of all 34 lecithotrophic y-naupliar morphospecies is presented, based on laboratory-reared final-instar specimens. This treatment is intended as a step towards a proper taxonomy and a revised classification of Facetotecta, which will involve detailed descriptions of both nauplii and cyprids. Until such work progresses, the present overview of the y-naupliar fauna of a single Okinawan locality known to be a hotspot of y-larval diversity is offered as a baseline for further surveys of Facetotecta elsewhere in the Indo-West Pacific and beyond.
The taxa of the subgenus Turritus of Cochlostoma (Cochlostomatidae) are analysed based on molecular and morphological data. The phylogenetic trees, based on ribosomal (16S) and nuclear (H3) DNA, indicate that the currently accepted taxonomy should be revised. Based on our data, there are 37 species in Turritus of which 5 are new to science: Cochlostoma (Turritus) pallgergelyi sp. nov., C. (T. ) muranyii sp. nov., C. (T. ) hallgassi sp. nov., C. (T. ) kontschani sp. nov. and C. (T. ) lacazei sp. nov. Of these, we describe the shells and the female genitalia and summarize the distributional data. Some samples (or set of samples) will remain undetermined for lack of data and these are reported in the appendix.
Though recent investigations have contributed substantially to our understanding of the Alpine-Dinaric radiation of the genus Zospeum Bourguignat, 1856, its southernmost member, Zospeum troglobalcanicum Absolon, 1916, has remained a taxonomic ghost. The assumed absence of type material, the insufficient original description, and the lack of new samples from its Western Balkan type locality have stymied further clarification. The recent discovery of a single syntype shell housed at the Natural History Museum Vienna now enables the first morphological assessment via 3D X-ray and SEM imaging. Based on this image data, different characters for assessing the southernmost members of the genus are determined and a lectotype is designated. Eleven allied species from 15 Western Balkan populations are described from museum material and recent sampling efforts: Z. amplioscutum Jochum & Ruthensteiner sp. nov., Z. biokovoense Jochum & Ruthensteiner sp. nov., Z. constrictum Jochum & Ruthensteiner sp. nov., Z. dubokidoense Jochum & Ruthensteiner sp. nov., Z. intermedium Jochum & Ruthensteiner sp. nov., Z. kolbae Jochum, Inäbnit, Kneubühler & Ruthensteiner sp. nov., Z. neuberti Jochum & Ruthensteiner sp. nov., Z. njegusiense Jochum & Ruthensteiner sp. nov., Z. njunjicae Jochum, Schilthuizen & Ruthensteiner sp. nov., Z. tortuosum Jochum & Ruthensteiner sp. nov. and Z. tumidum Jochum, Schilthuizen & Ruthensteiner sp. nov. One species, Z. kolbae, is described using DNA sequence data and one species, Z. simplex Inäbnit, Jochum & Neubert, 2021 for which DNA sequence data is already available, is supported by morphological data presented in this study. The DNA sequence dataset (COI, 16S and H3) is included here and implemented in the most recent phylogenetic reconstruction of the genus. A translation of Karel Absolon’s notes from the Balkan scientific expeditions is provided.
A taxonomic revision of the oil-collecting bees of the subgenus Epicharis (Epicharitides) Moure, 1945 is provided. A total of nine species were recognized: E. cockerelli Friese, 1900; E. duckei Friese, 1901; E. iheringi Friese, 1899; E. luteocincta Moure & Seabra, 1959; E. minima (Friese, 1904); E. obscura Friese, 1899, and E. rufescens Moure & Seabra, 1959, along with E. mesoamericana sp. nov. and E. lia sp. nov., two new species from the Central American and Amazonian provinces, respectively. Redescriptions, diagnoses, and figures of specimens of both sexes, floral records, distribution maps, an identification key, and an updated catalogue of all species of the group are also provided. In addition, the lectotype of E. duckei was also designated to stabilize the application of the name.
The genus Neocranaus Roewer, 1913 is revisited, its composition is expanded from two to five species and a new generic diagnosis is presented. Neocranaus albiconspersus Roewer, 1913, type species of the genus, is redescribed. The genus Tolimaius Roewer, 1915 syn. nov. is considered as a junior subjective synonym of Neocranaus, its sole member being transferred to Neocranaus – N. pectinitibialis (Roewer, 1915) comb. nov. – and redescribed here. The new combination Neocranaus laevifrons (Roewer, 1917) comb. nov. is proposed for Holocranaus laevifrons Roewer, 1917. The new species Neocranaus gladius Villarreal & Kury sp. nov. is described, from P.N.N. Yariguíes, Santander Department, Colombia. For the first time, the genital structure of this genus is illustrated. A key to the identification of the males of Neocranaus and some considerations about the reproductive biology of N. albiconspersus and N. pectinitibialis are presented.
Empty shells (thanatocoenoses) have been reviewed of species in the genus Granulina (Gastropoda: Granulinidae) from the lower shelf and upper bathyal zones off Mauritania and Western Sahara. We encountered nine species of which four were already known from off Mauritania. Four new species are proposed herein: Granulina reginae sp. nov., G. ronaldi sp. nov., G. sandrae sp. nov. and G. sigridae sp. nov. These four sympatric new species lack labial denticles and they probably form a phyletic clade with a common ancestor. Most hitherto known species in Granulina from the NE Atlantic Ocean and the Mediterranean possess labial denticles. One additional new species with denticles was left in open nomenclature because the material available was considered inadequate. Species in Granulina from Mauritania and Western Sahara have not been found off NW Morocco or the Canary Islands, and the species known from NW Morocco and the Canary Islands have not been found off Mauritania and Western Sahara. The southern extents of the distributions of the Mauritanian species are currently uncertain as additional sampling would be required off Senegal or further South. A key to Mauritanian species in Granulina is given.
Although initially described as a subgenus of Copris Geoffroy, 1762, Homocopris had long been treated as a junior synonym of Dichotomius Hope, 1838 (Martínez 1951) until it was reclassified as a distinct genus (Vaz-de-Mello et al. 2010). Herein, we revisit the taxonomy of Homocopris. In doing so: we describe two new species previously considered to represent the Brazilian population of Homocopris torulosus (Eschscholtz, 1822); revalidate Pinotus punctatissimus from synonymy under Homocopris torulosus and place it in Homocopris as had previously been done only informally (González et al. 2015; Rebolledo et al. 2017); recognize two new synonymies; and describe a new genus, Andinocopris gen. nov., which includes two former members of Homocopris. Presently, Homocopris includes four species: H. torulosus, H. punctatissimus (Curtis, 1845) comb. nov., H. grossiorum sp. nov. and H. williami sp. nov. Andinocopris includes A. achamas (Harold, 1867) gen. et comb. nov. and A. buckleyi (Waterhouse, 1891) gen. et comb. nov. Pinotus simulator Luederwaldt, 1936 is here considered a new junior synonym of Andinocopris buckleyi. An identification key to members of both genera is provided as well as images of diagnostic characters for all species. Finally, we discuss the placement of Andinocopris and Homocopris within Scarabaeinae and propose a new tribe, Homocoprini tribe nov., to include both genera.
• Mexican and German populations of L. sericata differ in their development times.
• Mexican L. sericata had a shorter development time at 20°C than German flies.
• At 30 °C, German L. sericata pupariated and eclosed earlier than the Mexican flies.
• Differences in study design make the comparison of developmental studies difficult.
Abstract
The cosmopolitan blow fly Lucilia sericata is often used in forensic case work for estimating the minimum postmortem interval (PMImin). For this, the age of immature specimens developing on the dead body is calculated by measuring the time taken to reach the sampled developmental stage at a given temperature. To test whether regional developmental data of L. sericata is valid on a global scale, the time taken to reach different developmental stages was compared between a population from Mexico and one from Germany at two different constant temperatures.
The German population of L. sericata was collected in Frankfurt/Main, while the Mexican population originated near Oaxaca de Juarez and was transported to Germany in the larval stage. Only the F1 generation was used to avoid adaption of the Mexican flies. Eggs were immediately placed at 20 °C and 30 °C. Five times 30 freshly eclosed larvae per replicate (n = 5) were then transferred to a cup of minced meat in separate containers. The larvae were checked every 8 h for migration, pupariation or emergence of adult flies. The time at which the first individual and 50 % of the specimens per container entered each of these stages, was recorded.
Significant differences in the time of development between the two populations were observed at both temperatures. At 20 °C, the first specimens of the Mexican population reached all developmental stages a little (< 1 day to < 2 days) earlier than the German L. sericata. At 30 °C, the Mexican flies also reached the post-feeding stage slightly earlier (0.2 days). However, at 30 °C, the German flies started pupariation significantly earlier (after 5 days) than the Mexican flies (6.9 days) and the adults from Germany also emerged earlier (10.5 days compared to 13.1 days). The same pattern was observed when looking at 50 % of the total number of specimens per container. A comparison with previously published developmental studies was difficult as the experimental design varied widely between studies. However, the results were within the range of most studies. Our study has shown that age estimation can vary widely depending on the population on which the reference data used for the calculations are based. This highlights the importance of using local and population-specific developmental data for estimating the age of blow flies in case work.

A comprehensive review of the enigmatic genus Masona van Achterberg is provided. Two new species are described from the USA: Masona neon Dal Pos & Martens sp. nov. from Puerto Rico, and Masona wow Dal Pos & Martens sp. nov. from California. A key to the world species of Masona is presented, together with a discussion of the morphology of the genus and an annotated catalogue of the species. [Masona] timpaynei Quicke, 2019, is excluded from Braconidae and placed as incertae sedis in the Ichneumonidae, subfamily Neorhacodinae.
The genus Armillipora Quate is recorded for the first time in Ecuador, with a new geographical record for Armillipora selvica Quate, 1996 and the descriptions of two new species, namely Armillipora muyu sp. nov. and Armillipora imitata sp. nov., doubling the total number of species in the genus. In addition, we make available the first DNA barcodes for the genus, providing a sequence of the 5´-end of the cytochrome c oxidase subunit I (COI) gene for A. imitata, A. muyu, and, A. selvica. Moreover, we describe the second known female of the genus and we provide a taxonomical key for the known males of the world. Finally, we build Species Distribution Models and discuss the potential distribution of the genus in the Neotropical region.
Sipuncula are marine unsegmented worms that can be found in benthic habitats, from shallow to deep-sea waters. In Mexico these worms have been scarcely studied. Among nine studies in the entire Mexican Pacific coasts, seven are from the central and northwestern Mexican Pacific. For over 80 years, only 24 species have been recorded. To improve the knowledge of the sipunculans from the central and northwestern Mexican Pacific, 501 specimens from three scientific collections of Mexico were revised. The specimens were collected by diverse methods from intertidal, subtidal, and bathyal depths (~1000 m), from 27 locations along the central and northwestern Mexican Pacific. Sixteen taxa belonging to nine genera and five families were identified. One species is recorded for the first time in the Mexican Pacific and five new species are described, one from intertidal and shallow subtidal depths: Phascolosoma (Phascolosoma) azteca sp. nov.; two from subtidal depths: Phascolion (Lesenka) salgadoi sp. nov. and Sipunculus (Sipunculus) bastidai sp. nov.; and two from bathyal depths: Apionsoma (Apionsoma) silviae sp. nov. and Apionsoma (Edmondsius) hendrickxi sp. nov.

Images of adults and genitalia for all treated species are given, along with a checklist of all Chinese species of Lecithocera.
Oceanic islands harbor a unique and distinct fauna and flora, usually isolated by distance and the deep sea, making them fascinating environments to study. Despite their importance, taxonomic accounts from Brazilian oceanic islands have only recently begun to focus on important groups such as the Syllidae family. In this article, we present detailed descriptions and illustrations of two new species, Brevicirrosyllis paulolanai sp. nov. from Trindade Islands, and Westheidesyllis splendida sp. nov. from Rocas Atoll. These two species belong to genera currently of uncertain affinities within the family, in both cases previously included in the Eusyllinae subfamily. Moreover, we provide updated identification keys for both genera to facilitate their future identification.
The erasipterid Sinoerasipteron xiaheyanensis Nel & Huang gen. et sp. nov. from the Moscovian Tupo Formation in Xiaheyan locality (China), is described and illustrated. It is the sixth species of the odonatopteran griffenflies from this locality. This new discovery confirms the high diversity of these flying predators in the insect assemblage.

Abstract
The black fly genus Simulium includes medically and ecologically important species, characterized by a wide variation of ecological niches largely determining their distributional patterns. In a rapidly changing environment, species-specific niche characteristics determine whether a species benefits or not. With aquatic egg, larval and pupal stages followed by a terrestrial adult phase, their spatial arrangements depend upon the interplay of aquatic conditions and climatic-landscape parameters in the terrestrial realm. The aim of this study was to enhance the understanding of the distributional patterns among Simulium species and their ecological drivers. In an ecological niche modelling approach, we focused on 12 common black fly species with different ecological requirements. Our modelling was based on available distribution data along with five stream variables describing the climatic, land-cover, and topographic conditions of river catchments. The modelled freshwater habitat suitability was spatially interpolated to derive an estimate of the adult black flies' probability of occurrence. Based on similarities in the spatial patterns of modelled habitat suitability we were able to identify three biogeographical groups, which allows us to confirm old assessments with current occurrence data: (A) montane species, (B) broad range species and (C) lowland species. The five veterinary and human medical relevant species Simulium equinum, S. erythrocephalum, S. lineatum, S. ornatum and S. reptans are mainly classified in the lowland species group. In the course of climatic changes, it is expected that biocoenosis will slightly shift towards upstream regions, so that the lowland group will presumably emerge as the winner. This is mainly explained by wider ecological niches, including a higher temperature tolerance and tolerance to various pollutants. In conclusion, these findings have significant implications for human and animal health. As exposure to relevant Simulium species increases, it becomes imperative to remain vigilant, particularly in investigating the potential transmission of pathogens.

We present new and atypical host records for 78 species, subspecies, species-groups, and variants of spider wasps (Hymenoptera: Pompilidae) from North America and South America. The records are listed in modified taxonomic order following the Catalog of Hymenoptera in America North of Mexico, Volume 2, Apocrita (Aculeata) (Krombein 1979). These records are an extension of previous host records reported by Kurczewski (2010), Kurczewski and Edwards (2012), and Kurczewski et al. (2017, 2020, 2022b).

The genus Lichnanthe Burmeister (Coleoptera: Scarabaeoidea: Glaphyridae) has been comprised of eight Nearctic species and contains the only New World members of their family. Here, two new species of arenicolous bumblebee scarabs are described from the central United States. The recent discovery of an undescribed Wyoming species led to the reevaluation of a dubious 134-year-old Nebraska Lichnanthe specimen, indicating that it also was an undescribed species. These two species, Lichnanthe brusti new species from central Wyoming and L. bruneri new species from central Nebraska are immediately distinguishable from all existing species of the genus by their square mandibles.

Anthrenus (Anthrenus) muehlei, a new species (Coleoptera: Dermestidae: Megatominae) from Iran
(2024)
A new species, Anthrenus muehlei Holloway and Herrmann (Coleoptera: Dermestidae: Megatominae), from Iran is described. Images of internal and external features are presented. Only female specimens were found and described, but the bursa copulatrix contains obvious sclerites enabling easy differentiation from all other known species from the Palaearctic A. pimpinellae complex. The possible function and taxonomic implication of the sclerites is mentioned.

We propose several nomenclatural changes for taxa in the subfamily Cladodinae and the lampyrid tribes Cratomorphini, Lamprocerini, Lampyrini, Photinini, and Pleotomini in the subfamily Lampyrinae (Coleoptera: Lampyridae). We present evidence for the correct year of description of Calotrachelum flavolineatum Pic, 1941, Diaphanes lateapicalis breveapicalis Pic, 1954, Photinus conradti Pic, 1940, and all species described by Charles Émile Blanchard. Spellings are corrected for Diaphanes lateapicalis breveapicalis Pic, 1954, Diaphanes latipennis dartevillei Pic, 1952, Diaphanes longecarinatus Pic, 1955, Diaphanes moultoni latemarginatus Pic, 1938, Lampyris olivieriana von Heyden, 1890, and Photinus reductemarginalis Pic, 1941. We propose Lucidota puertoestrellaensis Keller and Martin nomen novum to replace Lucidota boliviana Pic, 1927, and Photinus laticollis brasiliensis Keller and Martin nomen novum for Photinus laticollis latior Pic, 1941. Seventy taxa described as variations or aberrations in the tribes Cratomorphini, Lamprocerini, Lampyrini, Photinini, and Pleotomini in the subfamily Lampyrinae by McDermott (1966), are evaluated to subspecies with their availability determined based on ICZN (1999: Article 45.6). Photinus motschulskyi Zaragoza-Caballero, Zurita-Garcia, and Ramírez-Ponce, 2023 is synonymized under Photinus intercalatus Gemminger, 1870. Lastly, we correct the type species of the genus Lucidina Gorham, 1833, and address the dates of publication for fireflies described by Blanchard.

Climate change affects ecosystems worldwide and is threatening biodiversity. Insects, as ectotherm organisms, are strongly dependent on the thermal environment. Yet, little is known about the effects of summer heat and drought on insect diversity. In the Mediterranean climate zone, a region strongly affected by climate change, hot summers might have severe effects on insect communities. Especially the larval stage might be sensitive to thermal variation, as larvae—compared to other life stages—cannot avoid hot temperatures and drought by dormancy. Here we ask, whether inter-annual fluctuations in Mediterranean moth diversity can be explained by temperature (TLarv) and precipitation during larval development (HLarv). To address our question, we analyzed moth communities of a Mediterranean coastal forest during the last 20 years. For species with summer-developing larvae, species richness was significantly negatively correlated with TLarv, while the community composition was affected by both, TLarv and HLarv. Therefore, summer-developing larvae seem particularly sensitive to climate change, as hot summers might exceed the larval temperature optima and drought reduces food plant quality. Increasing frequency and severity of temperature and drought extremes due to climate change, therefore, might amplify insect decline in the future.
The vetigastropod material collected on Walters Shoal during Cruise MD208 of the Tropical Deep-Sea Benthos programme is documented. In total, 50 species were obtained, 30 of which are new and apparently endemic to the seamount. Of the other 20 species, eight are regionally endemic to the south-western Indian Ocean, 11 are more widely distributed in the Indo-West Pacific and one is possibly of deep-water Atlantic origin. The primary affinities of the fauna are with warm temperate South Africa and the tropical western Indian Ocean, but one species is potentially a seamount endemic of southern affinity. A new pseudococculinid genus living on decomposing bird feathers is described, a biogenic substrate association previously unknown in the Mollusca. The following new genera are described: Imbricoscelis gen. nov. and Pterodacna gen. nov. The following new species are described: Akritogyra crenulata sp. nov., Bathymophila williamsae sp. nov., Benthobrookula araneum sp. nov., Be. galeneae sp. nov., Be. laticostata sp. nov., Be. scalaroides sp. nov., Be. semisculpta sp. nov., Bruceina areneformis sp. nov., Calliostoma pantopunctatum sp. nov., Cantrainea herosae sp. nov., Carinastele achrosta sp. nov., Cornisepta marshalli sp. nov., Emarginula lentiginosa sp. nov., E. nodulicostata sp. nov., E. retrogyra sp. nov., E. salebrosa sp. nov., Fluxinella dufresneae sp. nov., Gibbula roseosticta sp. nov., Hadroconus scobina sp. nov., Kaiparathina monticola sp. nov., Lissotesta wareni sp. nov., Microcollonia miniata sp. nov., Mikro crassus sp. nov., Parviturbo cicatricosus sp. nov., Phragmomphalina candida sp. nov., Pterodacna boucheti gen. et sp. nov., Solariella asaphea sp. nov., Spinicalliotropis lepidota sp. nov., Stomatella multilirata sp. nov. and Trenchia mcleani sp. nov. The following new combinations are proposed: Brookula coronis Barnard, 1963 is transferred to Imbricoscelis gen. nov., Cantharidus nolfi Poppe, Tagaro & H. Dekker, 2006 is transferred to Kaiparathina Laws, 1941 and Solariella incisura Melvill, 1909 is transferred to Phragmomphalina Herbert & Williams, 2020. The following new synonyms are proposed: Carinastele wareni Vilvens, 2014 is a synonym of Bruceina cognata (Marshall, 1988); Fluxinella stellaris Bozzetti, 2008 is a synonym of Agagus stellamaris Herbert, 1991.
A contribution to the taxonomy of the genus Pelecium Kirby (Coleoptera: Carabidae: Peleciini)
(2024)
Pelecium Kirby, 1817 is a neotropical genus of flightless carabid beetles comprising 34 species, distributed from Panama to middle Argentina. Most species of Pelecium are known from short series and few localities, in some cases only from the holotype. Male and female abdominal terminalia are not described for the majority of the species, a situation that makes it difficult to describe new species or to study intraspecific variation. Here, we describe nine new species based on individuals from Brazil: Pelecium buckupi sp. nov., P. fistulosus sp. nov. and P. zaguryi sp. nov. from the Centre-West region, P. belloi sp. nov., P. chrissquirei sp. nov., P. straneoi sp. nov. and P. zophos sp. nov. from the Southeast region, and P. balli sp. nov. and P. grossii sp. nov. from the South region. We also provide new distributional records and descriptions of abdominal terminalia for twelve species: Pelecium atroviolaceum Straneo & Ball, 1989, P. bolivianum Straneo & Ball, 1989, P. cyanipes Kirby, 1817, P. helenae Straneo & Ball, 1989, P. laeve Chaudoir, 1854, P. negrei Straneo, 1962, P. drakei Quedenfeldt, 1890, P. punctatostriatum Straneo, 1970, P. purpureum Straneo, 1955, P. rotundipenne Schaum, 1860, P. striatum Straneo, 1955 and P. violaceum Brullé, 1838.
Previous phylogenetic analyses of the grass-specialist leafhopper tribe Chiasmini have resolved relationships among genera but have included few representatives of individual genera. Here the phylogeny of 20 Chinese species belonging to 8 chiasmine genera was investigated by combining DNA sequence data from two mitochondrial genes (COI, 16S) and two nuclear genes (H3, 28S). In both maximum likelihood (ML) and Bayesian inference (BI) analyses, relationships among genera were largely consistent with prior analyses, with most members of the tribe placed into two sister clades: (Exitianus + Nephotettix) and the remaining five sampled genera. To examine morphology-based species definitions in the taxonomically difficult genus Exitianus Ball, 1929, one mitochondrial gene (COI) and one nuclear gene (ITS2) were used to infer the phylogenetic relationships and status of two common and widespread species and compare the performance of different molecular species-delimitation methods. These analyses divide the included populations into two well-supported clades corresponding to current morphological species concepts but some inconsistencies occurred under the jMOTU, ABGD and bPTP methods depending on the which gene and analytical parameter values were selected. Considering the variable results yielded by methods employing single loci, the BPP method, which combines data from multiple loci, may be more reliable in Exitianus.
The Cladonematidae are a family of hydrozoans with a worldwide distribution and morphological adaptations for a benthic mode of life. Species of this family are characterized by high morphological variability, which has caused many taxonomical debates, mainly for the species of the genera Eleutheria Quatrefages, 1842 and Staurocladia Hartlaub, 1917. Herein, we describe Staurocladia dzilamensis sp. nov., a new species of crawling hydromedusa from the southern Gulf of Mexico. This finding also constitutes the first record of the genus Staurocladia for the Gulf of Mexico. The presence of additional nematocyst clusters, supplementing the apical one on the upper branch of the tentacles, places it within Staurocladia. The presence of exumbrellar buds, a conspicuous marginal ring of nematocysts, 6–11 bifid tentacles with lower branches longer than their upper counterpart, the cnidome with stenoteles of two size classes, and two nematocyst clusters on the upper branch supplementing the apical one, opposite placed alternately on its aboral and oral sides permits to differentiate S. dzilamensis from its congeners. A taxonomic key for the species of Staurocladia is provided.
This paper reviews little-known species of the dysderid spider genera Dysdera Latreille, 1804, and Dysderella Dunin, 1992 based on specimens collected in the Caucasus, Middle East, and Central Asia. After combining molecular phylogeny of five mitochondrial and three nuclear genes with morphological evidence, Dysderella is proposed as a junior synonym of Dysdera. In addition, three species are described as new to science: D. jaegeri Bellvert & Dimitrov sp. nov., D. naouelae Bellvert & Dimitrov sp. nov., and D. kourosh Bellvert, Zamani & Dimitrov sp. nov. Four combinations are proposed: Dysdera caspica Dunin, 1990 comb. rev., Dysdera transcaspica Dunin & Fet, 1985 comb. rev., Dysdera elburzica (Zamani, Marusik & Szűts, 2023) comb. nov. and Dysdera sancticedri (Brignoli, 1978) comb. nov. (ex. Dasumia Thorell, 1875). Furthermore, we report a first record of D. festai Caporiacco, 1929 in Turkey and its male cheliceral polymorphism. Our results illustrate the deficiencies that undermine the current taxonomy of this genus. For example, many species are described based on only one or few specimens or limited locality data. The advancements in DNA sequencing technologies applied to museum specimens reduce the need for fieldwork collection and export of fresh specimens. This highlights the significance of museum collections for improving research in this field.
A new family of Cyphophthalmi with disjunct Mediterranean distribution, Parasironidae fam. nov., is proposed. The new family comprises four genera and seven species. Cimmerosiro gen. nov., Tirrenosiro gen. nov. and Ebrosiro gen. nov. are described as new genera, and Tirrenosiro axeli gen. et sp. nov., Cimmerosiro krivolutskyi gen. et sp. nov., C. juberthiei gen. et sp. nov. and C. rhodiensis gen. et sp. nov. as new species. Parasironidae stands out by a set of characteristics that we recognize as predominantly plesiomorphic. These characteristics and the present distribution indicate the great age of the family, probably early Mesosoic. We attribute its origin to the western part of the Cimmerian terrane, and its current distribution and diversification of the major clades to geotectonic events during the Mesozoic. Additionally, a new sensory organ (sensilla) has been discovered in Cyphophthalmi. This organ is located on the pedipalp coxae and is believed to have a potential hygroreceptive function.
The monotypic banchine ichneumonid genus Shortia is rediscovered after 39 years, based on two new species from India, far away from the type locality in Australia: S. karumban Ranjith sp. nov. and S. manjapulli Ranjith sp. nov., collected from the Western Ghats, India. The generic concept of Shortia is revised. Both new species and the type species of the genus, S. siccula Gauld, 1984, are illustrated. A taxonomic key for the identification of species of Shortia is provided and the possible causes for the disjunct distribution are discussed.
Palaeosphryon menatensis gen. et sp. nov., first unambiguous representative of the longhorn beetle subfamily Prioninae from the Paleocene of Menat (France), is described and illustrated. The new fossil is placed into the tribe Prionini, showing some similarities with some species of the extant genera Osphryon (Papua New Guinea) and Titanus (Brazil, Colombia, Guianas, Ecuador, Peru), viz. in general body shape, antennomere 3 as long as first and second together but shorter than the length of fourth plus fifth, elongate elytra, and small spines on the lateral margin of the pronotum disposed in a relatively similar way as in Osphryon. Nevertheless, the exact affinities of the new fossil within the Prionini remain uncertain because of the lack of a recent phylogenetic analysis in which it could be integrated. This fossil beetle is exceptional for its very large size, with a body 70 mm long. Some other large longhorn beetles have been found in the same outcrop, and are awaiting description. The positions of the previously described Cerambycidae from Menat are also discussed. This exceptional fauna of Cerambycidae is in accordance with the current palaeoenvironmental reconstruction for the Menat Konservat-Lagerstätte, as a small maar lake surrounded by a warm and humid, probably evergreen forest.
Two new species of terrestrial isopods are described from iron ore caves in Brazil, within the Amazon biome, Circoniscus mendesi López-Orozco, Campos-Filho & Bichuette sp. nov. and C. xikrin López-Orozco, Campos-Filho & Carpio-Díaz sp. nov. (Scleropactidae). In addition, the knowledge of the distribution of Ctenorillo ferrarai Campos-Filho, Araujo & Taiti, 2014 (Armadillidae) is extended to Parauapebas, and Benthanoides tarzan Cardoso & Ferreira, 2023 to south area of the Campos Ferruginosos National Park, both in the State of Pará. Moreover, a distribution map and photographs of the species are given.
Three new species of Loxosceles Heinecken & Lowe, 1832 (Araneae, Sicariidae) from Brazilian caves
(2024)
Three new species of recluse spiders are described from Brazilian caves with both males and females. Loxosceles boqueirao Bertani & Gallão sp. nov. is found in the State of Bahia, in the Serra do Ramalho karst area, it belongs to the rufescens species group, and is closely related to L. cardosoi Bertani, von Schimonsky & Gallão, 2018 and L. carinhanha Bertani, von Schimonsky & Gallão, 2018 from the same karst area. Thus, there are now three species in the Serra do Ramalho karst area closely related, but noticeably distinct morphologically from other species of Loxosceles. Loxosceles planetaria Bertani & Gallão sp. nov. and L. bodoquena Bertani & Gallão sp. nov. are found in the State of Mato Grosso do Sul, in the Serra da Bodoquena karst area. They belong to the gaucho species group and are closely related to L. gaucho Gertsch, 1967. These are the first species of Loxosceles described from this karst area in the State of Mato Grosso do Sul. Loxosceles boqueirao sp. nov. and L. bodoquena sp. nov. bear some troglomorphisms and are, herein, proposed as troglobitic species, whereas L. planetaria sp. nov. is proposed as a troglophilic species. Brazil has now 22 described species of Loxosceles.
A remarkable morphologically and genetically distinct species of the genus Ero C.L. Koch, 1836 is described based on both sexes from the cloud forest of the island of Saint Helena: Ero lizae sp. nov. Another new species, Ero natashae sp. nov., is also described on the basis of morphological differences in the male and female genitalia. Both species were initially reported a single species, Ero aphana (Walckenaer, 1802), from the island by Unzicker (1977).
The remarkable sharpshooter Prodigiella silvanoi gen. et sp. nov. is described and illustrated (including the external form, color, male and female terminalia) from the Atlantic Forest of southern and southeastern Brazil (states of Paraná and Rio de Janeiro). The new genus can be distinguished from other Neotropical genera of the Cicadellini by a combination of various morphological features, including an asymmetrical aedeagus with a bifid shaft and peculiar basal and apical processes and ovipositor valvula II distinctly expanded beyond basal curvature, its dorsal margin with 35–40 teeth, and ventral margin without preapical prominence. A discussion comparing Prodigiella with superficially similar taxa of the genera Macugonalia Young, 1977, Ruppeliana Young, 1977, and Versigonalia Young, 1977 is provided. The discovery of this peculiar new genus indicates that much collecting work in the remaining parts of the Atlantic Forest is clearly and urgently needed.
The genus Spaeleoleptes was proposed by H. Soares in 1966 to accommodate the first Brazilian troglobitic species of harvestmen, Spaeleoleptes spaeleus H. Soares, 1966. In this work, we redescribe this species, including digital images of the type material and drawings of the male genitalia. Since its description, Spaeleoleptes has remained monotypic, and after 56 years, herein is described the second species of the genus, the troglobitic Spaeleoleptes gimli sp. nov. Both species share sexually dimorphic legs I and II with modified regions and swelling on the tibiae and patellae I and II; a penis with robust conductors covering all or part of the capsula interna and a capsula interna with two lateral projections. They are clearly separated by the shape of the modified region of the tibia; by the presence of an apical projection on the apical lamina of the pars distalis in S. spaeleus; and the lateral projections of the capsula interna, which is flattened in S. gimli. Spaeleoleptes gimli greatly increases the distributional range of the genus, as it is now recorded from caves located in two Brazilian phytophysiognomies from the Cerrado of Minas Gerais to the Caatinga of Bahia.
The ammonoids of the family Maenioceratidae from Givetian sedimentary rocks of the Anti-Atlas (Morocco) are investigated. The study is based on new collections stored in the Museum für Naturkunde, Berlin. The genera Maenioceras Schindewolf, 1933 and Afromaenioceras Göddertz, 1987 are revised; the genus Trimaenioceras is newly described. The species Maenioceras afroterebratum sp. nov., Maenioceras mzerrebense sp. nov., Maenioceras oufranense sp. nov., Maenioceras beckeri sp. nov., Afromaenioceras sulcatostriatum (Bensaïd, 1974), Afromaenioceras hiemale sp. nov., Afromaenioceras bensaidi sp. nov., Afromaenioceras brumale sp. nov., Afromaenioceras crassum (Bensaïd, 1974), Trimaenioceras klugi gen. et sp. nov., Trimaenioceras eculeus gen. et sp. nov., Trimaenioceras fuscina gen. et sp. nov. and Trimaenioceras paucum gen. et sp. nov. are described in detail.
A first-time analysis of taxonomically relevant characters, functional morphology, geographic distribution, ecoregion preference, and hypothetical host spiders of Pepsis basifusca Lucas (Hymenoptera: Pompilidae: Pepsinae) is presented. This analysis is compared with other Nearctic species in Vardy’s (2005) Pepsis menechma species-group, particularly P. cerberus Lucas and P. elegans Lepeletier which are suspected parasitoids of trapdoor spiders. Pepsis basifusca females differ from females of these species in possessing a rounded gena-postgena in dorsal view; straight mid and hind tibial spurs; short hind tibial inner spur; and short, very stout, and backward slanted hind tibial bristles. Pepsis basifusca Level III Ecoregions comprise mountains, plateaus, highlands, and tablelands, often at high elevation (~3,000–5,000 feet (914–1,524 meters), from Utah, Colorado, Kansas, and Missouri to Panama. Pepsis basifusca, the smallest Nearctic congener, should be expected to capture comparatively small mygalomorph spiders like some other species in Vardy’s (2005) Pepsis menechma species-group. Based on taxonomic, morphological, biogeographical, and potential host spider criteria, P. basifusca should probably be removed from this group and transferred to another species-group.

Lectotypes are designated for the following species: Chrysomela albicollis Fabricius, 1787; Chrysomela nobilitata Fabricius, 1787; Chrysomela quadrifasciata Fabricius, 1787; Chrysomela quadriguttata Fabricius, 1781; Galleruca atomaria Fabricius, 1801; Galleruca decemguttata Fabricius, 1801; Galleruca fasciata Fabricius, 1798; Galleruca humeralis Fabricius, 1801; Galleruca lunata Fabricius, 1801; Galleruca nitida Fabricius, 1801; Galleruca obsoleta Fabricius, 1801; Galleruca petaurista Fabricius, 1801; Galleruca quadrinotata Fabricius, 1798; Galleruca sellata Fabricius, 1801. The species status is restored for Chrysomela quadriguttata Fabricius, 1781 and Alagoasa areata (Germar, 1824) comb. nov. The following new combinations are proposed: Phenrica quadriguttata (Fabricius, 1781), Asphaera nitida (Fabricius, 1801), Phenrica obsoleta (Fabricius, 1801), Alagoasa areata areata (Germar, 1824), Alagoasa areata decempunctata (Latreille, 1833), Alagoasa areata escuintla Bechyné, 1955, Alagoasa areata macromela Bechyné, 1958, Alagoasa areata praecessa Bechyné, 1959, Alagoasa areata recuperata Bechyné, 1959; all comb. nov. New placement: Galleruca avicenniae Fabricius, 1792 is removed from Alticini and placed in Galerucini incertae sedis; Galleruca trifasciata Fabricius, 1801 is removed from Chrysomelidae and placed in genus Ora Clark, 1865 (Scirtidae Fleming, 1821).
The “trachystreptoform” species of Spirostreptidae, i.e., species which would formerly have been ascribed to the tribe Trachystreptini, from the Udzungwa Mountains are (re)described, including one new genus and five new species: Attemsostreptus reflexus Akkari & Enghoff, 2019, A. cataractae Enghoff sp. nov., A. leptoptilos Enghoff sp. nov., A. julostriatus Enghoff sp. nov., Lophostreptus tersus (Cook, 1896) (= L. ptilostreptoides Carl, 1909 syn. nov.), L. magombera Enghoff sp. nov., and Udzungwastreptus marianae Enghoff gen. et sp. nov. The type material of Lophostreptus regularis Attems, 1909 (= L. tersus) is discussed. The discussion includes paragraphs on the classification and the Udzungwa fauna of Spirostreptidae, on grouping of the Udzungwa trachystreptoform species in relation to altitude, and on the possibly recent immigration of A. reflexus and L. tersus into the Udzungwa Mts.
