Intense surveys across museum collections allowed for describing eight new species: Karillantu amazonaensis sp. nov., Karillantu ecuadoriensis sp. nov., Karillantu lauretensis sp. nov., Karillantu napoensis sp. nov., Karillantu obidensis sp. nov., Karillantu paraensis sp. nov., Karillantu pastazaensis sp. nov., and Karillantu peruviensis sp. nov. We provide descriptions of the genus and species, a redescription of Karillantu macrocephalus comb. nov., an identification key, and a distribution map. To determine the sister-group relationships of Karillantu gen. nov., we conducted a phylogenetic analysis based on seven gene fragments, resulting in the largest Paederinae phylogeny up to date and a hypothesis about Karillantu gen. nov. placement. The analysis resolved the genus within the tribe Lathrobiini, nested in the informal clade of genera traditionally assigned to the subtribe Lathrobiina. We also provide information on the phylogenetic position of 17 newly sequenced taxa expanding our understanding of Paederinae relationships. The present research underscores the importance of museum collections in studying biodiversity of poorly-known groups, especially in the tropical regions.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"27 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747502","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 morphological adaptive features of the limb long-bones of extant elephants, the heaviest living terrestrial animals, have previously been highlighted; however, their bone microanatomy remains largely unexplored. Here we investigate the microanatomy of the six limb long-bones in Elephas maximus and Loxodonta africana, using comparisons of virtual slices as well as robustness analyses, to understand how they were adapted to heavy weight-bearing. We find that the long bones of elephant limbs display a relatively thick cortex and a medullary area almost entirely filled with trabecular bone. This trabecular bone is highly anisotropic with trabecular orientations reflecting the mechanical load distribution along the limb. The respective functional roles of the bones are reflected in their microanatomy through variations of cortical thickness distribution and main orientation of the trabeculae. We find microanatomical adaptations to heavy weight support that are common to other heavy mammals. Despite these shared characteristics, the long bones of elephants are closer to those of sauropods due to their shared columnar posture, which allows a relaxation of morphofunctional constraints, and thus relatively less robust bones with a thinner cortex than would be expected in such massive animals.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"20 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701880","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}

Despite the vital character of its function, some of its features remain poorly understood. This is particularly the case for osteoderms, which are bone plates in the skin that occur widely but inconsistently throughout the tetrapod tree of life. Elucidating their function and evolutionary history requires systematic approaches, but this is hampered by the lack of a consistent and comprehensive catalogue of osteoderm expression. Squamate reptiles (lizards and snakes) harbour the greatest diversity of osteoderms in terms of shape, distribution, and expression among living tetrapods, and thus represent an ideal study system. We conducted the first qualitative investigation of osteoderm expression in squamate reptiles. Based on 1339 micro-computed tomography samples and 584 mentions in the literature, we report here osteoderms in 46% of lizard genera, making them 85% more common than prior literature suggests. We found substantial discrepancies with prior literature in the Varanidae and the Lacertidae, where osteoderms are common or ubiquitous, respectively. In squamate reptiles as a whole, osteoderm prevalence amounts to 25%. Our findings provide the groundwork for future systematic investigations, thus potentially providing new insight into evolutionary trajectories and constraints that shaped present-day biodiversity.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"115 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677248","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}

We present the largest (super)family-level phylogeny of Ctenostomatida to date. We resolved the three major clades (A–C) that were recognized previously. Clade A included endolithic taxa Penetrantiidae, Immergentiidae, and Terebripora ramosa, the latter two being sister taxa. Other taxa in this clade were Nolella, Arachnidium, Pottsiella, and Paludicella. Clade B was composed of Alcyonidioidea and Multiporata. The genus Alcyonidium was revealed as non-monophyletic, with the two recovered clades likely to be characterized by contrasting reproductive modes (brooding and zygote spawning). Members of the presumptive brooding clade had insertions of possible exogenous origin in their 18S and 28S ribosomal RNA genes, which might be the result of horizontal gene transfer. Clade C was sister to the Cheilostomatida and was composed of Vesicularioidea, Hislopioidea, Walkerioidea, and three clades of Victorellidae. Anguinella and Hypophorella were consistently sister taxa, but their position was unstable. Results are discussed in light of morphology, reproduction, and previous phylogenetic hypotheses. A revised classification is proposed. Timwoodiellina natans is transferred to Hislopia, Vesicularia spinosa to Amathia, and Monobryozoon ambulans to Alcyonidium. Members of the putative zygote-spawning Alcyonidium clade are transferred to Alcyonidioides in the family Alcyonidioididae.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"11 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603161","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}

To further understand the evolutionary history of M. obscurus, we generated nuclear and mitochondrial data from five modern and 11 ancient specimens from Eastern Europe and the Near East. We reconstructed a tip-dated phylogeny using a 4.3-kilobase fragment of mitochondrial DNA. We estimated the time to the most recent common ancestor of M. arvalis and M. obscurus to be 130 thousand years ago (kya), correlating with the Eemian interglacial, a period characterized by the reduction of open habitats suitable for microtine species. In the Lesser Caucasus, we recorded a turnover of two lineages probably related to environmental changes at the end of the Pleistocene. Using three published and three newly generated nuclear genomes, we confirmed the general population structure and divergence times inferred from the mtDNA.

Conversely, material from Cannita Cave (Palermo, Sicily) attributed to H. pentlandi is less robust, more elongated and smaller. 3D geometric morphometric analysis performed on the symphyseal sagittal cross-section further support a closer morphological affinity of the Amoroso mandible to San Ciro Cave specimens and H. amphibius, suggesting an attribution to the latter.

We generated a dated, multilocus phylogeny of the mambas and assessed species boundaries. Species distribution modelling (SDM) was used to assess the past and present potential connectivity between allopatric populations of D. angusticeps and D. polylepis. The phylogeny suggests that diversification of the crown clade began c. 6 Mya and, contrary to previous suggestions, we found no convincing signal of species-level diversification within D. polylepis or D. angusticeps.

The remaining 34 individuals exhibited morphological variation, yet the limited number of adult individuals and deteriorated state of these specimens precluded further morphospecies’ classification. Nonetheless, the observed morphological diversity among those individuals suggests the presence of additional undescribed species within this complex. Molecular analyses revealed at least six cryptic Ancistrocheirus species. Future molecular and morphological research might solve this cryptic species complex.
