We comment on the cranial anatomy of this taxon and propose a new reconstruction of the skull and mandible. Contrary to previous interpretations, the entire rostrum and most of the palate are not preserved in this specimen. We also suggest that some proposed plesiomorphic characters may result from incomplete ossification due to immaturity. These new observations are compiled into a new morphological phylogenetic dataset designed to address the monophyly of ‘Avicephala’, the group comprising the Late Permian gliding reptiles Weigeltisauridae, and the Late Triassic chameleon-like Drepanosauromorpha. We recover Weigeltisauridae as stem-saurian diapsids and Drepanosauromorpha as sister-group to Trilophosauridae among archosauromorphs, thus implying the paraphyly of ‘Avicephala’. Drepanosauromorphs and trilophosaurids are recovered as sister-taxa for the first time, as supported by several cranial and postcranial synapomorphies. This new phylogenetic position of Drepanosauromorpha reduces the group’s ghost lineage that now does not necessarily cross the Permian–Triassic boundary. However, much remains unknown of the early history of trilophosaurids and drepanosauromorphs, and of the evolution of arboreality in Triassic archosauromorph reptiles.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140910595","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 cool stenothermic ecology of nearly all diamesines produces a typical amphitropical pattern of absence at tropical latitudes, except at high elevation. Recent attention has focused on the species discovery, while evolutionary relationships at the generic and tribal level have remained inadequately understood. Current classification implies analogous evolutionary diversification in each hemisphere (boreal and austral). To test this concept, we used six genetic markers (18S, 28S, CAD1, COI-5p, COI-3p and COII) and fossil calibrations to produce a well-supported and resolved time-calibrated phylogeny of the subfamily. Austral and boreal diamesines indeed are reciprocally monophyletic lineages, with estimated Jurassic divergence (130-196, 164 Ma). The boreal Protanypodini, previously understood to be a tribe within Diamesinae, is excluded and elevated here to subfamily rank as Protanypodinae stat. nov. Ancestral austral diamesines probably originated in South America and successively reached New Zealand, Australia and South Africa during the Cretaceous-Paleogene. The Holarctic tribes Diamesini and Boreoheptagyiini probably originated in the Eastern Palaearctic with further dispersal/vicariance into the Western Palaearctic, Nearctic, East, and very likely dispersed southwards to montane East Africa and Borneo.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140895421","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}

One species occurs in South America and at least two extinct species are known from New Zealand. It has been proposed that these Southern Hemisphere merganser lineages were founded by at least two independent dispersal events from the Northern Hemisphere. However, some morphological and behavioural evidence suggests that Southern Hemisphere mergansers may form a monophyletic clade that descended from only a single dispersal event from the Northern Hemisphere. For example, Southern Hemisphere mergansers share several characteristics that differ from Northern Hemisphere mergansers (e.g. non-migratory vs. migratory, sexual monochromatism vs. sexual dichromatism, long vs. short pair bonds). We sequenced complete mitogenomes from the Brazilian merganser and an extinct merganser from New Zealand—the Auckland Island merganser. Our results show that the Brazilian and Auckland Island mergansers are not sister-taxa, and probably descend from two separate colonization events from the Northern Hemisphere at least 7 Mya.

Taking an integrative taxonomic approach incorporating phylogenomic, morphological, and geographical information, the genus is herein revised. Of the four species currently placed in the genus, two are retained: Chanbria regalis Muma, 1951 and Chanbria serpentinus Muma, 1951. Eremochelis plicatus (Muma, 1962) is transferred to this genus because it is consistently recovered in a clade with Chanbria based on several phylogenetic analyses using hundreds of loci recovered from ultraconserved element data. In this study, we re-analyse previously acquired genomic data to assess former species hypotheses and identify new morphological synapomorphies that support the monophyly of Chanbria. The genetic data support the synonymization of Chanbria rectus Muma, 1962 syn. nov. with C. regalis. Furthermore, we synonymize Chanbria tehachapianus Muma, 1962 syn. nov. with C. regalis because C. tehachapianus was erected based on limited morphological information and lack of geographical separation between other populations of C. regalis. Two new species, Chanbria brookharti sp. nov. and Chanbria mapemes sp. nov., are described.

Most osteoglossid fossils come from a 25-million-year interval in the early Palaeogene, when these fishes were distributed worldwide in both freshwater and marine environments. Despite their biogeographic and palaeoecological relevance, and a relative abundance of well-preserved material, the evolutionary relationships between these Palaeogene forms and extant bonytongues remain unclear. Here we describe a new genus of bonytongue from early Eocene marine deposits of Morocco, represented by an articulated, three-dimensionally preserved skull with associated pectoral girdle. This taxon is characterized by an elongated snout, contrasting with the short jaws usually found in marine representatives of the clade. A revision of morphological characters in bonytongues allows us to place this new genus, together with other marine and freshwater Eocene taxa, within crown osteoglossids and closely related to extant arapaimines. The discovery of the new Moroccan taxon hints at a previously underestimated eco-morphological diversity of marine bonytongues, highlighting the diverse trophic niches that these fishes occupied in early Palaeogene seas.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140607549","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 some fireflies are suspected of using combined signalling, this view has so far not been supported by empirical evidence, and these species have been viewed more as outliers. In this study, we have investigated the visual and olfactory capability of sexual communication of a night-active glow-worm firefly Lamprohiza splendidula (Linnaeus, 1767). We recorded and categorized the behaviour of searching males in reaction to four different experimental treatments, in which the females could be located based solely on visual or olfactory cues or a combination of the two. The pheromone-only treatment attracted significantly more males than the control, thus confirming pheromone utilization in sexual communication of this species. This work represents the first direct evidence of combined pheromone and bioluminescence use in fireflies and refutes the hypothesis of exclusive use of light in courtship of the nocturnal species. We theorize that this life strategy is likely to be inherent in the whole genus and possibly common in all glow-worm firefly species.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140547428","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}

A significant structural feature, the cephalothorax-cheliped attachment, is one of the sources of this variation but is still poorly understood or resolved in phylogenetic terms. The presence (and wide intrafamily disparities) of a lateral carapacial sclerite associated with this articulation is the main contributor to the diversity and this is investigated by us and shown to have valuable information for paratanaoidean phylogenies. We used integrative taxonomy to evaluate the status of several described colletteid genera, Caudalonga, Macrinella and Pseudoarthrura, based on analysis of COI and 18S genes, comparison with molecular data from ten other paratanaoidean families and detailed morphological study including confocal imaging of whole specimens, with the ‘sclerite’ a prime target for analysis. The results supported the establishment of a new family, Caudalongidae fam. nov., extracted from the overburdened Colletteidae, the narrow-bodied taxa defined principally by the small cheliped sclerite partly covered by a wide membrane and a short one-articled uropodal exopod. Apart from redescriptions/redefinitions of the genera Caudalonga, Macrinella, and Pseudoarthrura, two new genera Facultatotanais gen. nov. and Universitatotanais gen. nov. are erected and six new species are described, Caudalonga kurilensis sp. nov., F. bios sp. nov., U. freie sp. nov., U. gandavensis sp. nov., U. harvardi sp. nov., and U. jagiellonensis sp. nov.
