The group currently comprises four species widely distributed across the Palaearctic and Afrotropic regions: <i>R. bocharicus</i> (Central Asia), <i>R. clivosus</i> (from northern Africa and the Levant through Arabian Peninsula and eastern Africa to southern Africa), <i>R. ferrumequinum</i> (from western Europe and northern Africa through the Balkans and Middle East to Central Asia and India) and <i>R. nippon</i> (southern and central China, Korea, and Japan). The broad ranges and geographical variations within these species have led to the proposal of numerous subspecies. The phylogenetic relationships and intraspecific variation of the <i>R. ferrumequinum</i> group were investigated using a genetic approach. One mitochondrial marker and five nuclear markers were sequenced and supplemented with available sequences for all four species of the group. Our study revealed five major lineages within the <i>R. ferrumequinum</i> group, resulting in the recognition of four currently known species and identification of a new species. The prior name available for this lineage/species is <i>R. acrotis</i>. The relationships between the lineages varied depending on the chosen marker, leaving the interspecific relations within the <i>ferrumequinum</i> group unresolved. In addition, the results indicated that <i>R. clivosus</i> experienced historic introgression from northern Africa and the Levant, resulting in replacement of its mtDNA by that of <i>R. ferrumequinum</i>. Together, this study introduces a new <i>Rhinolophus</i> species, which increases the number of species in the <i>ferrumequinum</i> group to five.","PeriodicalId":49334,"journal":{"name":"Zoologica Scripta","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139561382","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}

Evaluating patterns in species description dates and their relationship with macroecological variables can help guide where taxonomic efforts should be focused. Therefore, we aim to assess the Linnean shortfall in the knowledge of New World coralsnake biodiversity. We modelled species description dates and estimated that approximately one‐third of the coralsnake diversity remains unknown. The undescribed species are evolutionarily closely related to the already described species. Moreover, recently described species in the group have more restricted geographic ranges and tend to be small‐bodied. The western Amazon and the dry diagonal (i.e. Caatinga, Cerrado, and Chaco) are the areas with the oldest description dates. However, assemblages in these areas have the largest average geographic distances to the type locality of their species, suggesting that little taxonomic effort has been dedicated intrinsically to these regions. We suggest that allocating taxonomic efforts to the dry diagonal and the use of integrative taxonomic techniques for better species delimitation are imperative to fill the Linnean shortfall for the New World coralsnakes.","PeriodicalId":49334,"journal":{"name":"Zoologica Scripta","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139382822","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}

In this study, a total of 154 hare specimens were used to clarify their taxonomic status. Based on multiple lines of evidence, including observations and comparisons of external morphological characteristics, skull morphometrics and genome-wide single nucleotide polymorphism (SNP) datasets, four hare species were recognised. <i>Lepus yarkandensis</i> and <i>Lepus timidus</i>, which have obvious morphological characteristics, were identified as two distinct species, as previously reported. Combining the integrated morphological and molecular datasets with the relevant literature, we proposed suggestions on the classification of the more controversial hares. Due to molecular and morphological similarities, hares in northern and central Xinjiang were divided into two subspecies of <i>Lepus tolai</i>, namely, <i>Lepus tolai lehmanni</i> and <i>Lepus tolai centrasiaticus</i>. Despite similar external morphological characters, hares in the southwest Pamir Plateau and its surroundings can be distinguished from <i>L. tolai</i> by differences in skull morphology and genetic divergence and were, therefore, considered a subspecies of <i>Lepus tibetanus</i>, <i>Lepus tibetanus pamirensis</i>. Furthermore, we found that hybridization and introgression occurred between sympatric or parapatric hares, especially between <i>L. yarkandensis</i> and <i>L. tibetanus pamirensis</i>, <i>L. yarkandensis</i> and <i>L. tolai centrasiaticus</i>, and <i>L. tolai lehmanni</i> and <i>L. timidus</i>.","PeriodicalId":49334,"journal":{"name":"Zoologica Scripta","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139373395","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}

In the last decades, molecular analyses have been further increasing the number of Amazonian vertebrate species, hidden under traditional taxonomy due to morphological convergence. Bats represent an interesting example, as the number of recognized bat species is continuously expanding with the identification of numerous cryptic taxa. Studies combining different lines of evidence, such as morphometric and molecular approaches, have been playing an important role in addressing knowledge gaps on Neotropical bat diversity. Within the Phyllostomidae family, the dwarf little fruit bat <i>Rhinophylla pumilio</i> is a forest-dependent species, with a disjunct distribution in the Amazonian and Atlantic forests. Moreover, different karyotypes have been recovered across the species distribution, suggesting this might be one more example of cryptic diversity. Here, we test this assumption by identifying geographic patterns of morphological and molecular variation within the species' entire range of distribution. Our results point to an overall morphological and morphometric homogeneity, except between Atlantic Forest and Amazonian specimens, with significant dissimilarity among some cranial characters. Furthermore, genetic data suggest a rapid and recent diversification, with these two lineages most likely corresponding to speciating taxa. Within the Amazonian forest, our molecular analyses also recovered four additional lineages, likely encompassing intraspecific diversity. Furthermore, studies are required to confirm the need for a taxonomic rearrangement.","PeriodicalId":49334,"journal":{"name":"Zoologica Scripta","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139066983","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}

However, there are also troves of molecular data accumulated from past studies using Sanger sequencing, often at fine taxonomic scales. Combining both sources of data is an obviously appealing possibility, but it can also lead to inconsistency due to high levels of missing data, disparities in the scale of Sanger versus genomic datasets, and little overlap in sequences across terminals. To provide an empirical investigation of the potential of such ‘hybrid’ datasets, we combined data from ultraconserved elements (UCEs) for 183 species of Cryptini (Ichneumonidae, Hymenoptera) with a previously existing dataset of 7 loci and morphological data including 308 species plus outgroup taxa. Bioinformatics pipelines allowed recovery of ‘legacy’ markers from the bycatch of UCE sequencing, reducing the problem of limited character overlap. The resulting tree combining Sanger and UCE data is highly supported and includes dense taxon sampling of the group, allowing for a better understanding of the global radiation of Cryptini. The Neotropical region had the highest phylogenetic diversity but the lowest level of phylogenetic dispersion when corrected for standardized effect size, while the Oriental fauna showed the highest level of phylogenetic dispersion.

In this study, we assess the phylogeography of seven natural beds of <i>M. donacium</i> (17 to 42° S), to reveal the geographic distribution of the genetic diversity through the analysis of 278 sequences of the mitochondrial gene COI. Sequences of the nuclear genes 18S and 28S were used to evaluate the divergence of COI haplogroups. Two divergent parapatric mitochondrial haplogroups were found, which lacked divergence at nuclear markers (18S and 28S); this mito-nuclear discordance allows inferring that there is no reproductive isolation of mitochondrial haplogroups. The North haplogroup is the only one present at the northernmost site, while only the South haplogroup was present in Cucao in the south. Between 28° and 32° S, coincident with a coastal biogeographic break at 30° S, both haplogroups are in sympatry. Haplogroups differed in their genetic structure, with the North haplogroup representing a single, highly diverse population and the South haplogroup with genetic differentiation and more restricted genetic diversity and gene flow. The divergence in mitochondrial haplogroups without nuclear divergence suggests a past scenario of geographic isolation in the northern and southern areas, without developing reproductive isolation, followed by secondary contact.

In addition, long-standing taxonomic and nomenclatural issues complicate the studies of this genus. Herein, we examine the diversity of <i>Ambassis</i> in Peninsular Malaysia using an integrative taxonomic approach and a large set of recently collected specimens from this region. Our initial morphological observations of 260 specimens revealed the presence of eight species, identified as <i>Ambassis dussumieri</i>, <i>Ambassis interrupta</i>, <i>Ambassis kopsii</i>, <i>Ambassis macracanthus</i>, <i>Ambassis nalua</i>, <i>Ambassis octava</i>, <i>Ambassis urotaenia</i> and <i>Ambassis vachellii</i>. We then sequenced the barcode fragment of the mitochondrial cytochrome c oxidase subunit I (COI) gene for 122 of our specimens, representing all eight morpho-species. Automatic species delimitation methods recovered nine Molecular Operational Taxonomic Units (MOTUs) because <i>A. interrupta</i> is made of two MOTUs. Morphological re-examination within <i>A. interrupta</i> detected variation at one character, congruent with molecular delimitation. Overall, our integrative approach unveiled rich species-level diversity within the genus <i>Ambassis</i> in Peninsular Malaysia, with the presence of nine species. Further comparisons between our COI dataset and the COI sequences archived in the Barcode of Life Data System (BOLD) from specimens of <i>Ambassis</i> broadly collected in tropical Asian regions, indicated regional-scale hidden diversity and identification conflicts, triggering the need for a complete taxonomic revision of this genus.","PeriodicalId":49334,"journal":{"name":"Zoologica Scripta","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138575663","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}
