This evolutionary transformation is characterized by more canalized (restricted) elbow and wrist mobility and a diminished prehensile (grasping) ability of the digits, requiring a suite of osteological modifications. Here, we employ micro-computed tomographic (μCT) imaging to reconstruct the forelimbs of Confuciusornis based on a new specimen from the Lower Cretaceous Jehol Group in western Liaoning, China. Our rendering is the first three-dimensional reconstruction of the forelimb for this key Early Cretaceous bird, revealing critical osteological details that advance our understanding of early flight evolution. The reconstruction reveals previously unrecognized features including canalized structures in the elbow and wrist joints, a relatively smaller triangular pisiform, a hook-like projection on the alular metacarpal, and distinctive digital morphology. We provide detailed morphological descriptions of the elbow, wrist, and metacarpophalangeal and interphalangeal joints, which are essential for evaluating flight capabilities, forelimb folding mechanics, and manual grasping ability. Furthermore, our data support the presence of a cushion-like bone at the distal end of the alular metacarpal of Confuciusornis and demonstrate fusion of this cushion-like bone with the cranial condyle.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"119 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145498372","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}

Plectranthias, the most species-rich genus, has been suspected of non-monophyly since its last revision over 40 years ago. In this study, we explore the phylogenetic relationships of anthiadids using a multigene dataset (one mitochondrial and four nuclear genes) from 103 specimens across 19 genera, with a focus on IWP Plectranthias. Our results confirm the polyphyly of Plectranthias, revealing seven distinct clades. Based on this new phylogenetic framework and morphological re-examinations, we propose a taxonomic revision, including the resurrection of the genera Pelontrus, Sayonara, Xenanthias, and Zalanthias, and the establishment of Aepysomanthias and Poroanthias Tang and Chen gen. nov.

This study explores the phylogeography of the complex, incorporating novel samples from its Western range: Algeria and the French Atlantic coast. We analysed 66 new COI and 65 new EF1 sequences alongside 869 published COI and 116 EF1 sequences. Based on these markers, all new specimens belonged to O. longicaudum s.s. This species displayed limited genetic differentiation among localities and a nearly significant isolation-by-distance pattern, although the most abundant haplotypes spanned from the Eastern Mediterranean to the Atlantic. This weak genetic structure, unusual for a species with lecithotrophic larvae, likely reflects large effective population sizes. A survey of gonad developmental stages showed that most Algerian individuals spawned between July and August but some showed reproductive activity in March—a period unreported for broadcast spawners—suggesting possible brooding in Algeria. However, additional unlinked genetic markers are needed to include the Algerian and Atlantic genotypes in a global multilocus biogeographical dataset in order to delimit species.

However, proper assessment of their relevance to systematics is still limited by the scarcity of ultrastructural data allowing for fine-tuning homology recognition among the different kinds of granules. In this study, the morphology of cortical granules from five hypotrichous ciliates was examined using electron microscopy for the first time, revealing them to be extrusomes of different types. The results suggest the widespread presence of extrusomes among hypotrichs and explain their biogenesis after electron microscopy observations. Concurrently, phylogenetic analyses were performed using the Small Subunit Ribosomal RNA (SSU rRNA) gene to map the distribution of these organelles onto different taxa and discuss their evolution within the Dorsomarginalia and Kentrurostylida. Our findings indicate that pigmentocysts appear at various phylogenetic positions and emerged relatively late, exemplifying convergent evolution, and that similarities among extrusome types are relevant for delineating natural groups. Based on our results, new insights to hypotrichs systematics are proposed based on cortical granules: (i) the morphology and distribution patterns of the granules are now used to delineate major clades of the order Kentrurostylida, shedding light on the non-monophyly of the genera Anteholosticha, Bakuella, and Neobakuella; (ii) the redefinition of Pseudokeronopsidae, Pseudourostylidae, and Thigmokeronopsinae; and (iii) the recognition of pigmentocysts as a diagnostic feature and possible synapomorphy of the sister-clade of Stylonychinae, within Dorsomarginalia.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"39 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145472865","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}

Although the monophyly of Tellinoidea is well corroborated by morphological and molecular data, the monophyly of the individual families and their relationships remain contentious, hampering further macroevolutionary studies. By using an ultraconserved element probe set recently developed for the class Bivalvia, we captured 825 ultraconserved elements from 33 fresh and historical museum specimens and produced a phylogeny for Tellinoidea with strong support for its internal relationships. Our analyses recovered Donacidae as monophyletic, whereas Solecurtidae were inferred as paraphyletic, and Psammobiidae, Semelidae, and Tellinidae were resolved as polyphyletic lineages. The results reinforce the need for reassessment of these families, because phylogenetic evidence suggests, for example, that semelids and the genus Sanguinolaria are nested within Tellinidae. Leveraging this phylogenetic framework, we estimated ancestral states of four key traits: burrowing depth, feeding habit, tentacle form, and the number of siphonal tentacles in the incurrent aperture. Our results show lineage-specific variations of the siphon anatomy and specialization for deposit-feeding behaviour. Overall, we also highlight evolutionary convergences and discuss potential scenarios for the diversification of tellinoids in shallow-water environments.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"216 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145472837","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 provide an updated and refined phylogenetic hypothesis that resolves relationships among closely related taxa and supports the recognition of a new theraphosid clade. Preliminary analysis of this clade suggests that unconventional characters of the male palpal bulb may have untapped potential for generic-level differentiation within Theraphosidae. Further, the recovered topologies support the recognition of a new genus, Tandayarachne gen. nov. The new genus is composed of a new species from the Tandayapa Cloud Forest Station, Western Ecuador, and a previously misplaced species of Neischnocolus Petrunkevitch, 1925 from Colombia. Notably, the paratype female of the latter species is reassigned to Neischnocolus and proposed here as a new species based on distinct spermathecal morphology. Integrating our phylogenetic hypothesis with character optimization and ancestral character state reconstruction, we identify evolutionary trends in keel-nested characters, further providing support for genera delimitation on the studied clade. We discuss the current impediments facing the taxonomy of the subfamily Theraphosinae, with a specific focus on the underestimation of proper morphological analysis of the palpal bulbs in taxonomic assessments. Finally, we discuss the geographical distribution of the new genus and propose plausible scenarios to explain its disjunct distribution.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"1 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145472840","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}

Some lineages are exclusively stygomorphic species, such as Anaspides eberhardi (Ahyong, 2016), whereas others, such as Anaspides richardsoni (Ahyong, 2016), have surface and cave forms. Two different models for speciation have been suggested for recent colonization events of caves: the climatic relict hypothesis and the adaptive shift hypothesis. The major difference is the absence (climatic relict hypothesis) or presence (adaptive shift hypothesis) of gene flow during divergence, corresponding to allopatric and parapatric speciation. Herein, we present a phylogenetic analysis of the obligate cave-dwelling species A. eberhardi and two closely related species using double digest restriction-site associated DNA (ddRAD) and COI datasets. Despite the detected mito-nuclear discordance, the extensive ddRAD datasets clearly support the monophyly of each species. However, we detected one instance of localized introgression into A. eberhardi from a surface population of A. richardsoni, whereas syntopically occurring populations with an undescribed species showed no evidence of interbreeding. Our data support a single origin of A. eberhardi during the Pleistocene, followed by underground dispersal and extinction of surface populations, all in correlation with glacial events. This clearly favours the climatic relict hypothesis as the mode of speciation.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"4 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145427749","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}

Comparatively fewer multivariate analyses of shape have been conducted in invertebrates, partly due to difficulties in identifying unambiguously homologous landmarks. We present the first landmark-free deterministic atlas analysis (DAA) of shape and integration between insect tagmata, characterizing intraspecific variation in the blowfly Calliphora vicina (Diptera: Calliphoridae). We recover sexual dimorphism in the shape of all three tagmata, even where differences are gradational or indistinguishable from visual inspection. Partial least square analysis reveals high integration between tagmata within females, but not males. In males, integration is low between the thorax and abdomen, and absent between the head and abdomen. This reflects independence in the mechanisms underlying shape variation, including the development of highly sexually dimorphic eye morphologies and of structures that house the genital apparatus. Furthermore, we find a relationship between within-segment integration and morphological variance suggesting within-tagma integration may be facilitating shape variation in C. vicina. These intraspecific insights highlight the potential for landmark-free studies investigating the influence of development on shape and integration between species and across clades. Moreover, these techniques may aid forensic entomology, where sex determination can assist with postmortem interval estimates.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"38 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145310742","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}
