Our coalescent species tree showed divergence-time estimates ranging between 7.67 and 3.51 Mya, indicating that a marine transgression played a key role in this group diversification.

Sphenodraco was recovered in our phylogenetic analysis as a component of a clade including Homoeosaurus and Kallimodon. To evaluate the ecomorphology of the new taxon, we compare fossil rhynchocephalians with the extant tuatara and squamates. We quantify the diversity of body proportions in lepidosaurs systematically, inferring lifestyle for extinct rhynchocephalians. Our analysis suggests that fossil rhynchocephalians had a diverse array of substrate uses, with some categorized as good climbers, and with Sphenodraco showing the extreme condition of limb elongation found in strictly arboreal lizards. This new taxon is here regarded as the first predominantly or even strictly arboreal rhynchocephalian.

This phenomenon is caused by extinctions on the drifting Indian plate triggered by extensive volcanism on the one hand, and, on the other, the subcontinent’s relative proximity to neighbouring landmasses, which facilitated faunal exchange as early as during India’s northward passage. Here, we present a description of the first mayfly fossils from Cambay amber, consisting of two male imagoes from the family Leptophlebiidae, clade Atalophleboculata. We describe one of the studied specimens as Aikahika veta gen. et sp. nov.

The Chinese population of Ps. hawaiiensis closely resembles previous reports but has more ventral cirri. This is the first detailed account of the morphology, ontogenesis, and SSU ribosomal DNA sequence of Pe. faurei. Key ontogenetic features of Pe. faurei include: (i) the proter retains the parental adoral zone, while the opisthe develops a new oral primordium; (ii) five frontoventral anlagen form five cirral rows per daughter cell; (iii) marginal cirral rows and dorsal kineties develop intrakinetally, while dorsomarginal kineties develop de novo; and (iv) macronuclear nodules fuse into a single mass before division. Morphological, ontogenetic, and phylogenetic differences distinguish Pe. faurei from the spirofilid type genus Hypotrichidium Ilowaisky, 1921. Phylogenetic analyses place Pe. faurei within the strongylidiid clade, separate from the spirofilids.

The classification of fleas is further hampered by a few classical taxonomic keys published over 40 years ago and, in many cases, they are not digitized and thus not easily accessible. More recently, molecular data have been utilized with great success in an attempt to resolve some of the higher level taxonomic uncertainties for Siphonaptera, but detailed phylogenetic studies of fleas are still scarce. Here we conduct a comprehensive phylogenetic and evolutionary review using 148 taxa within the infraorder Ceratophyllomorpha with 4689 aligned sites derived from seven different molecular markers. Bayesian phylogenetic analyses supported the monophyly of 34/48 genera (71%), and also supported the monophyly of most members within the Leptopsyllidae, Ceratophyllidae, and Ischnopsyllidae. The dated phylogeny constructed shows that diversification within the Ceratophyllomorpha dates back to ~23.1 Mya, and from this period onwards, the evolution of the fleas included herein was influenced by both host association and host distribution. The most common hosts of the Ceratophyllomorpha group were various families of rodents, with the exception of the Ischnopsyllidae, that was specific to the order Chiroptera. The rich extant Ceratophyllomorpha diversity is mainly confined to the Palaearctic region, and this geographic pattern was most evident for the family Leptopsyllidae. The present study emphasizes the need for a comprehensive taxonomic revision for the order Siphonaptera. Since the current taxonomic schemes are mainly based on morphology, future focus should be given to those species where no molecular data are available and where molecular data are scarce.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"272 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144520856","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 paper presents a well-preserved and rich sample of Trischizolagus from the Megalo Emvolon-4 (MVL) fossil site near Thessaloniki (Greece) and provides for the first time the full cranial anatomy of T. dumitrescuae, the most common species known from the Late Ruscinian of SE Europe.

From 718 individual ostracod valves of the species Cyprideis torosa, we extracted size (length and height) and valve width (from focus-stacked photographs), and we used geometric morphometrics to analyse the shape of valve outlines. Variability of C. torosa was investigated on different geographical (Baltic Sea, Central Germany, and Mediterranean area) and geological (Holocene to living) scales. We found that sexual differences were greater in shape than in size and that populations on our geographical scale showed a differentiation in size. Dimorphism in width was investigated in detail for the first time for ostracods and showed strongest dimorphism within the size traits. The examination of the relationship between size and shape revealed sex-specific, regional, and temporal patterns. All size traits of C. torosa showed allometry consistent with Rensch’s rule. Isolation of the Mansfeld Lakes populations from marginal marine environments might have contributed to morphological differentiation as expression of possible speciation. We suggest that morphological variability in C. torosa results from a combination of sex-specific and scale-dependent geographical phenotypic plasticity and regional sexual and fecundity selection pressures on the sexes.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"74 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144516137","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}
