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.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"3 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176807","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 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.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"48 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176581","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 description of a second species, Allosaurus europaeus, based on a posterior part of an articulated skull and a sequence of cervical vertebrae (ML 415) collected at Praia de Vale Frades in Lourinhã, has been controversial, and its validity has been challenged. A detailed description of a new sample of cranial fossil material collected at Andrés that can be confidentially attributed to Allosaurus is presented. In addition, a comprehensive phylogenetic assessment of the Morrison Formation fossil record of Allosaurus is also performed. This analysis indicates that only two valid Allosaurus species were present in the Late Jurassic ecosystems of North America: Allosaurus fragilis and Allosaurus jimmadseni. An emended diagnosis for Allosaurus fragilis is here proposed. The Portuguese specimens MNHN/UL.AND.#, ML 415, and MG 27804 are here interpreted as belonging to Allosaurus fragilis. This interpretation has important implications to better understand the evolutionary history of the theropod fauna of the Lusitanian Basin, supporting the existence of close biogeographic relationships between the landmasses on both sides of the proto-North Atlantic Ocean during the Kimmeridgian–Tithonian.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"58 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144153394","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}

Many of these have been well studied in attempts to understand their functional importance, and some aspects of cochlear morphology have been shown to correlate with hearing ability across taxa. Among the unique features of the therian inner ear is the presence of bony structures supporting the sensory epithelia. While these have been implicated in the development of extended high-frequency hearing, their functional role remains unclear. In this study, I use micro-computed tomography (μCT) imaging to take quantitative measurements of the bony spiral laminae and cochlear scalae through the length of the basilar membrane. I present an analysis of the variation showing how these change from the cochlear base to the apex, and how they differ between clades. I find considerable variation in the structures between different clades, particularly in the area of the cochlear scalae which show differences between terrestrial and aquatic species. These results provide a broad survey demonstrating a diversity that could be further exploited to explore functional significance in more detail. A cursory comparison shows correlation between various morphological measures and hearing ability, with the dimensions of the basilar membrane appearing the most useful to make predictions.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"9 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144153392","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}

These adaptations, often described as constructive traits or regressive features, reflect trade-offs in metabolic requirements and energy utilization in response to life in darkness. In this study, we describe two new cavefish species, Triplophysa yangi sp. nov. and Triplophysa wenshanensis sp. nov., from karst subterranean rivers in Yunnan Province, China. Triplophysa yangi is distinguished from its congeners by its bilaterally expanded anterior swim bladder chambers, which protrude from the enlarged bony capsule, distending the lateral body wall and becoming externally visible. Additionally, it has highly developed pectoral and pelvic fins with filamentous extensions. Triplophysa wenshanensis can be identified by its nearly cone-shaped head, triangular head profile, and light brown to flesh pink body colour with faint brown blotches. Molecular phylogenetic analysis places both species in the hypogean group of Triplophysa, increasing the number of cavefish species in this genus from 39 to 41. The most distinctive feature of T. yangi, its expanded anterior swim bladder chambers protruding beyond the enlarged bony capsules, might represent an innovative stygomorphic trait among Chinese cavefish. This trait is hypothesized to be associated with a unique energy-saving buoyancy mechanism, crucial for the ability of the species to remain suspended and survive in perpetual darkness.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"4 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144145496","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 results revealed two monophyletic groups of populations that were more similar in their shell morphology and differed in the size of the dart apparatus. They represented two subgenera with seven mtDNA clades. The subgenus Hygromia s.s. consisted of a nominal Hygromia cinctella. The subgenus Riedelia included: Hygromia limbata s.s. and its subspecies Hygromia limbata hylonomia, Hygromia tassyi and Hygromia pyrenaica sp. nov. The taxonomic status of two independently evolving lineages could not be resolved. Hygromia odeca and Hygromia veprium were synonymized with Hygromia limbata and Hygromia gofasi with Hygromia tassyi. No morphometric shell character alone ensured the determination of any Hygromia species and the microsculpture showed only minor differences. Among genitalia features, the appearance of a love dart had the greatest taxonomic value. Many recognized taxa were restricted to narrow territories, implying a complex evolutionary history of the genus in the Pyrenees and their foothills.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"20 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122803","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}

Through a community science approach, also known as citizen science, we refined the definitions of the colour pattern morphs of the Japanese natricine snake, Rhabdophis tigrinus. Despite the limited number of geographical observations, R. tigrinus has been classified into six distinct colour pattern morphs over the past decades: three region-specific morphs, two hypopigmented morphs, and one hyperpigmented morph. However, our newly collected community science images of R. tigrinus revealed that 123 colour pattern combinations of R. tigrinus have emerged across the Japanese Archipelago. The community science images with detailed geographical information also provided insights into the anti-predatory functions of R. tigrinus colour patterns through an association between blotch size and habitat temperature via the flicker-fusion effect. Our results highlight the advantages of using community science data in overcoming observational biases and investigating intraspecific colour pattern variations across a wide geographical range.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"85 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144088317","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}
