Capitellidae constitute an important family of polychaetes valued for their usefulness as indicators of environmental health in many ecosystems, yet their diversity at mid-ocean ridges remains largely unexplored. Here, we report three species of Capitellidae across three genera from Indian Ocean ridges and formally describe two of them, including Capitella longqiensis sp. nov. from the inactive zones near the active vents of the Longqi vent field on the Southwest Indian Ridge, Notomastus sp. TVG12 from organic matter-rich sediments on the same ridge, and Decamastus branchiatus sp. nov. collected on an active vent chimney in the Edmond vent field on the Central Indian Ridge. Phylogenetic analyses support their assignment to three different genera. Within Capitella, C. longqiensis and the whale-fall species Capitella iatapiuna fell in separate subclades, indicating two independent historical colonizations of chemosynthetic ecosystems. Decamastus branchiatus is sister to an undescribed capitellid from a Red Sea vent, and Notomastus sp. TVG12 was closely related to Notomastus from Pacific nodule fields, supporting a potential biogeographical linkage between these regions. These new capitellids add to the diversity of annelids in the Indian Ocean, underlining the need for further sampling efforts to understand in full the biodiversity at these vents eyed for deep-sea mining.

The taxonomic conundrum of pipistrelle-like or pipistrelloid bats remains one of the unsolved challenges posed by African Chiroptera. Historically, their cryptic morphology has led to a frequently confused classification and cast doubt on taxonomic arrangements at both genus and species levels. While molecular analyses and extensive reviews of specimens housed in collections worldwide have clarified many systematic relationships among pipistrelloid bats, some species still require validation, leaving gaps in our overall understanding of the systematics of the group. The Congo rainforest, one of Africa's least explored regions, remains underrepresented in systematic studies of pipistrelloid bats. In this study, we combine the use of two mitochondrial genes and cranial morphometric analyses to provide an updated perspective on African pipistrelloid bats, focusing on new material from Equatorial Guinea sampled over multiple years. We confirm the placement of Af. musciculus and Af. crassulus within the genus Afropipistrellus. The former was previously included in Hypsugo, while the latter lacked generic confirmation. Additionally, we describe a new species of Pipistrellus from Bioko Island, Central Africa, uncovered during systematic bat surveys in the region. Further surveys in the Congo rainforest are needed to unveil African bat diversity and its phylogenetic relationships fully.

Deep-sea hydrothermal vents host lush communities of animals relying on bacterial chemosynthetic primary production, where intimate symbioses often form. Peltospiridae are a family of gastropods endemic to hot vents, whose members exhibit a variety of feeding strategies ranging from bacterial grazing to total reliance on endosymbiosis. Here, we report and describe two new peltospirid snails, Peltospira gargantua sp. nov. and Lirapex pantagruel sp. nov., from two recently discovered vent fields on the Mid-Atlantic Ridge. Peltospira gargantua is clearly distinct from other congeners by its much larger size, differences in the number and arrangement of epipodial tentacles, and notably, a hypertrophied oesophageal gland. Lirapex pantagruel is also the largest known species in the genus, differing from other species also by shell shape and sculpture. Phylogenetic reconstructions using the mitochondrial cytochrome c oxidase subunit I (COI) gene agree with their respective generic placements. An expanded oesophageal gland in peltospirids was known only from the endosymbiotic genera Chrysomallon and Gigantopelta, where it is used to host symbionts, indicating that P. gargantua is probably also endosymbiotic. This would represent another case of likely convergently acquired oesophageal endosymbiosis in the family, and the first record of endosymbiotic gastropod from Mid-Atlantic Ridge vents.

The oldest representatives of the amisegine cuckoo wasps are described from inclusions in mid-Cretaceous Burmese amber. Four monotypic new genera are described and illustrated: †Cenomanisega krombeinigen. et sp. nov., †Cretamisega mandibularisgen. et sp. nov., †Protognathosega depilisgen. et sp. nov., and †Telistosega intermediagen. et sp. nov. Additionally, †Miracorium amicasp. nov. is described and illustrated based on the discovery of the first female in the genus †Miracorium. We used Bayesian inference to establish the phylogenetic position of the new fossils within Chrysididae. The new fossils exhibit specialized modifications in the female mouthparts and apparatus for oviposition, which are consistent with the feeding and egg-laying habits observed in the modern Amiseginae. Our findings suggest that these traits evolved ≥100 Mya and might have been crucial in the early diversification of the clade as specialized parasitoids of walking stick eggs.

The mesh-web weaver family Dictynidae s.l. has been labelled a ‘tailor’s drawer’ family because it contains taxonomically unorganized and often evolutionarily distant species. Previous molecular phylogenetic studies using limited taxonomic sampling and legacy target genes involving representatives of the family have been consistent in: (i) exhibiting low branch support values and (ii) the recovery of genera and species currently classified as dictynids outside of Dictynidae. The genera within the family and the relationships among dictynid genera have never been rigorously tested using genomic-scale data. Here, we use exemplar dictynid species from the most currently recognized dictynid genera and ultraconserved elements (UCEs) recovered in silico from low-coverage, whole-genome sequencing plus Sanger data to resolve the phylogenetic placement and relationships of genera within the family Dictynidae s.l. The resulting phylogeny, along with morphological evidence, supports several taxonomic updates to the group: Argyronetidae stat. reinst., Lathyidae fam. n., and Dictynidae s.s. are included in Dictynoidea. Argyronetidae stat. reinst. include the genera Altella, Arctella, Argenna, Argyroneta, Chaerea, Devade, Hackmania, Iviella, Mizaga, Paratheuma, Saltonia, Tricholathys. The family Lathyidae fam. n. is proposed to include the genera Afrolathys gen. n. (Af. madagascariensis sp. n. and Af. tanzanica sp. n.), Analtella stat. reinst.

Clown beetles (Histeridae) are stable components of carrion communities, but their prey range is poorly recognised. An indirect way to deduce species’ diet is to study the functional morphology of their mandibles. The use of a multimodal approach in the study of Margarinotus brunneus, Margarinotus striola succicola, Saprinus semistriatus, and Saprinus planiusculus revealed a hidden morphological diversity in their mandibles. Geometric morphometric analysis showed inter- and sex-specific differences in their shape. Synchrotron X-ray microtomography revealed variability in musculature between genera and the presence of a joint-like structure at the basal margins in the Saprinus species. Scanning electron microscopy showed variation in the surface of inner margins. Traditional morphometrics revealed differences in mandibular arc according to beetle species, sex, and left and right body sides. All species retained a roughly 17° asymmetry, with the right mandible always having the higher arc. We conclude that Saprinus species are adapted for cutting and puncturing soft-bodied prey, whereas Margarinotus beetles also feed on hard-bodied prey. Future studies should consider our findings for better planning of prey-choice experiments. Emphasis should be placed on recognising whether subtle differences in mandible shape involve differences in diets. This will be critical to determine the role of species in carrion ecosystems.

All species retained a roughly 17° asymmetry, with the right mandible always having the higher arc. We conclude that Saprinus species are adapted for cutting and puncturing soft-bodied prey, whereas Margarinotus beetles also feed on hard-bodied prey. Future studies should consider our findings for better planning of prey-choice experiments. Emphasis should be placed on recognising whether subtle differences in mandible shape involve differences in diets. This will be critical to determine the role of species in carrion ecosystems.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"10 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144210845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The genus Zigrasimecia, also known as the iron maiden ant, represents a peculiar lineage spanning most of the Cretaceous period and characterized by armed mouthparts. Despite recent publications that have contributed to our understanding of the past diversity within this genus, its true extent remains underestimated and its morphological variations poorly comprehended. In this study, we introduce two new species of iron maiden ant, Zigrasimecia bellator sp. nov. and Zigrasimecia sinusoidal sp. nov. Using micro-computed tomography scanning and three-dimensional reconstruction techniques, we highlight their distinctive morphological features, particularly certain setae and microstructures of the body. Additionally, we present an updated identification key tailored for Zigrasimecia workers. Through comparative morphology, we propose hypotheses regarding the predatory behaviour of iron maiden ants. Our findings contribute to a deeper understanding of the morphological diversity within this fascinating ant genus.

Crocodyliforms are poorly known from the Early Jurassic Lufeng Formation of China, and a new specimen of Platyognathus hsui is by far the most complete specimen yet known. It shares with the missing holotype and the neotype the very unusual features of a dentary caniniform that is polygonal in cross-section and the complete fusion of the dentary symphysis, and the new specimen provides four additional features diagnosing the species. Features such as a relatively broad rostrum and a posteroventrolateral process on the squamosal place it with taxa closer to extant crocodylians than are Orthosuchus and Protosuchus, as an early branching relative of the Gobiosuchidae. The oldest previous record of the gobiosuchid lineage was from the late Barremian stage of the Early Cretaceous, and this extends the fossil record of the lineage back by 67 Myr. We recognize a new superfamily, Gobiosuchoidea, to include Platyognathus hsui and gobiosuchids.

Neotheropoda is the core clade of predatory dinosaurs that originated in the Triassic and became highly diversified and globally distributed by the Early Jurassic. Currently, six species of Neotheropoda have been described from Early Jurassic localities in Yunnan Province, south-western China. Here we describe a new specimen from the Lufeng Formation in central Yunnan, representing a non-coelophysoid, non-averostran neotheropod. Osteohistological analysis indicates the immaturity of the specimen. Computed tomography scans reveal the internal morphology of trunk vertebrae, implying a more developed postcranial skeletal pneumaticity in averostran-line neotheropods than previously thought. Phylogenetic analysis finds the new specimen as the closest sister-taxon to Averostra (Ceratosauria + Tetanurae). It does not form a unique subclade with the previously described Lufeng Formation taxa Shuangbaisaurus anlongbaoensis and Sinosaurus triassicus. Instead, Sh. anlongbaoensis and Si. triassicus are found as sister-taxa, indicating that the former may be a subjective junior synonym of the latter. Although the new specimen has a unique combination of character states, and a potential autapomorphy, we conservatively refrain from establishing a new taxon, due to its immature status and the lack of information on postcranial anatomy in other Yunnan theropods. Regardless, this specimen bridges a morphological gap between non-averostran and averostran theropods.

The genus Scolopendra is a taxonomically complex group, with species displaying intricate evolutionary radiation across Mediterranean islands. The present work aims to explore the diversity patterns of the Mediterranean banded centipede S. cingulata across Sicily, some surrounding islands, and Southern Calabria, investigating its genetic (COI and 28S) and phenotypic variation. Through extensive sampling and the analysis of 92 COI sequences from 82 sampling sites, three distinct structured lineages were identified in the study area: Sicily/Malta (SM), Eastern Peloritani Mountains (EP), and Aspromonte (As). Conversely, 28S sequences did not reveal the same genetic structure observed in the COI, probably due to the occurrence of introgression phenomena. Morphological assessments showed significant variation among clades. Colour pattern analysis revealed distinguishable morphotypes among the three clades. SM juveniles exhibit a unique light morphotype, contrasting with the dark dichromatic morphotype common to As and EP juveniles. These findings seem to suggest multiple colonisation events and prolonged isolation periods in Sicily, which shaped the current diversity of S. cingulata on the island. The genetic distinctiveness and apparent parapatric distribution of SM and EP, with limited evidence of admixture, highlight the need for further studies to fully understand the evolutionary history and potential taxonomic implications for this taxon.
