Subterranean fauna provide critical services and can act as bioindicators; however, a significant portion of this diversity is unknown. The family Bathynellidae are neglected taxa of tiny subterranean crustaceans, with only 112 species described in 36 genera and three subfamilies worldwide. Their conservative morphology, small size, and delicate exoskeleton make their dissection, observation, and study very difficult. However, in recent years, molecular tools have been used to support morphology and reconstruct phylogenies to analyse the relationships among taxa and understand their origins. In this paper, using molecular and morphological data, we recognize 37–41 new Bathynellidae putative species from Australia, including a new genus and species (Queenslandbathynella gen. nov. spinosa sp. nov.), here described, belonging to a new subfamily (Queenslandbathynellinae subfam. nov.), expanding the morphological knowledge of the family. We present a multigene phylogeny inclusive of many described and undescribed taxa from Australia and worldwide, with four genes (cytochrome c oxidase subunit I and 16S, 28S, and 18S ribosomal RNA), that supports the erection of a new genus and subfamily, which provides a new molecular framework for Bathynellidae.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"47 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142805315","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}

Using micro-computed tomography (μCT), we document the peculiar anatomy of the new taxon, which is characterized by extreme dental morphology, including one massive tooth on the maxilla and dentary, flat cheek teeth, and an array of other diagnostic features that readily differentiate it from all other amphisbaenians. We also redescribe the oldest named African amphisbaenian, Todrasaurus gheerbranti, from the late Palaeocene of Morocco, using μCT. Phylogenetic analysis recovers Terastiodontosaurus and Todrasaurus as sister taxa and provides strong support for a sister-group relationship of those two large-toothed amphisbaenians with extant Trogonophis. Accordingly, Todrasaurus shows that the divergence of crown Trogonophidae occurred much earlier than currently thought. Our survey of μCT scans reveals that Terastiodontosaurus, Todrasaurus, and Trogonophis are characterized by a great enamel thickness on their teeth, a feature that is absent in other examined amphisbaenians. Size estimates show that Terastiodontosaurus was the largest known amphisbaenian ever to have lived, with an estimated skull length of >5 cm. Based on new muscle data of Trogonophis, we estimate very high bite forces for Terastiodontosaurus, which would allow it to crush a wide variety of snails.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"1 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679061","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}

Modes of antennal concealment are particularly variable, underscoring the importance of protecting these essential sensory structures. Understanding the evolution of these morphological features has been hindered by a weak understanding of the family’s basal phylogeny, and corresponding patterns of niche-use and morphological evolution. Cretaceous amber fossils have been proliferating, filling in important morphological gaps right around the time of the family’s explosive radiation. Here we describe 10 new species from Cretaceous Burmese ambers, six of them representing new genera: Palaeabraeus glabrus gen. nov. et sp. nov. (Abraeinae); Pseudacritus extinctus gen. nov. et sp. nov. (Abraeinae); Miculissima excavata gen. nov. et sp. nov. (unplaced to subfamily); Placatister cascus gen. nov. et sp. nov.

A revised phylogenetic analysis that includes these taxa supports previous hints that inquilinous forms were prevalent and diverse during the Cretaceous. These results also support the contention that pressures in these environments to protect the critically important sensory apparatus, the antenna, were strong, driving multiple origins of two of the more protective configurations among extant taxa. Some of the new genera remain unplaced to subfamily, underscoring the gaps that still remain in the early fossil record for the family, and the continued need for more comprehensive analyses of combined data from extant taxa, along with additional extinct forms that we may assume will continue to be discovered.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"35 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673016","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 present study used a combination of molecular (barcoding), colour pattern, and other morphological data to explore the possible existence of hidden species diversity within this species. Based on the available samples, analyses of molecular data uncovered seven well-supported (.96–1.00 Bayesian posterior probabilities) candidate species, with 1.6%−8.5% genetic divergence between them. These, in addition to two more candidate species without genetic data, exhibited a combination of consistent colour pattern and other morphological differences that supported their distinction. The present study redescribes P. ngamensis, which is confined to the Okavango and upper Zambezi (sub)basins, and describes eight new species: two from the Kwanza Basin and six from the Kasai sub-basin. The fact that some of the species occur allopatrically, whereas others are sympatric and even syntopic indicates the complex palaeogeographical history of these basins. In addition, the high species diversity discovered in the Kasai sub-basin seems to be related to its highly peculiar hydrography. Accurate delimitation of species boundaries and mapping of their distribution is crucial for conservation assessments and guiding their protection.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"98 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637638","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}

Here we erect and describe the extinct species Chersina langebaanwegi sp. nov. on the basis of abundant material that provides information on its morphological variation. The referral of the new species to the genus Chersina is supported by phylogenetic analysis which includes the Malagasy ploughshare tortoise, sharing the presence of a single gular shield covering a very long gular protrusion with Chersina spp. and a domed shell with C. langebaanwegi sp. nov. The material from Langebaanweg represents the oldest fossil evidence of this genus.

To help bridge this gap, we present a new morphological phylogeny that includes representatives of all major clupeiform lineages. The data matrix consists of 192 characters, drawn from 79 extant and 37 fossil taxa and selected to be readily identifiable in fossils. Most clupeiform families are recovered as monophyletic, and their interrelationships are generally compatible with previous morphological hypotheses. The phylogenetic positions of six fossil clupeiform taxa are resolved, as the results of all analyses (unconstrained/constrained parsimony and Bayesian inference) are consistent. Twenty-one fossil taxa are incertae sedis, including two species of Ellimmichtyiformes, which are recovered as Clupeoidei in the parsimony analyses. The relationships of the rest of the fossils are interpreted with varying degrees of certainty. The evolution of key morphological characters is discussed in light of the new results, and four fossil taxa are proposed as calibration points for future dating studies.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"2 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142597786","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}

Comparative analysis of the evolution of soft-tissue structures in the fish skull is often limited under traditional approaches, while new imaging techniques like diceCT (diffusible iodine-based contrast-enhanced computed tomography) allow for high-resolution imaging of muscles in situ. Darters (Percidae: Etheostomatinae) are a diminutive and species-rich clade of lotic freshwater fishes, which show diverse head shapes believed to be associated with different foraging strategies. We used diceCT to sample all major cranial adductors and abductors responsible for movement of the jaw, hyoid, operculum, and suspensorium from 29 species. We applied comparative phylogenetic approaches to analyse the evolutionary trends in muscle size across the clade. We found two major patterns: (i) darter cranial muscles show fundamental trade-offs relating to investment in musculature, as well as buccal expansion vs. biting attributes; early divergence in muscle size appears to be associated with shifts in habitat use and foraging; (ii) darter adductor mandibulae show high variation in architecture (fibre orientation, divisions).

Except for Simulium sergenti, the following six species Simulium equinum, Simulium paraequinum, Simulium pseudequinum, Simulium turgaicum, Simulium balcanicum, and Simulium lineatum are the most widely distributed species of the subgenus Wilhelmia in the Palearctic region. However, the conspecific diversity and evolutionary history of these species are not yet well understood. In this study, therefore, we used mitochondrial COI and nuclear ITS1-2 sequences to perform species delimitation tests, and demographic and phylogeographic analyses to understand candidate species and evolutionary history of the seven species. While our results did not support the species status of S. balcanicum, S. turgaicum, and S. lineatum, it did suggest several candidate species within S. equinum and S. pseudequinum. Molecular clock analysis revealed that significant branching events occurred in the Pliocene, and demographic fluctuations in the populations occurred intensely during the Pleistocene. Overall, the results indicated that Anatolia has served as a significant refugium for ancestral haplotypes, and it is an important dispersal corridor between the eastern and western Palearctic for Wilhelmia species.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"87 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142563094","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}
