Because female insects frequently lack taxonomically useful morphological characters, their taxonomic assignment is challenging without sufficient locality information. Using the cryptic species complex previously treated as “<i>Pterostichus</i> (<i>Rhagadus</i>) <i>polygenus</i> Bates” as a model, this study presents a novel procedure based solely on morphological data for the taxonomic assignment of female type specimens that lack sufficient locality information. Without <i>a priori</i> species hypotheses, males were divided into morphotypes based on the morphology of the endophallus, a genital structure that has recently been found to be useful in the taxonomy of insects, particularly Coleoptera. Then, geometric morphometrics of the pronotum followed by discriminant analysis were conducted using females obtained from the same localities as the males (not including female type specimens). The obtained discriminant function unambiguously assigned all female type specimens to the morphotypes, including those without sufficient locality information, resulting in the following Japanese <i>Rhagadus</i> Motschulsky species: <i>Pterostichus microcephalus</i> (Motschulsky) ( = <i>Pterostichus kimurai</i> Morita syn. nov.), <i>Pterostichus negylopus</i> sp. nov.

A morphological phylogeny of Japanese and Korean <i>Rhagadus</i> species was constructed, and their differentiation process is discussed. In addition, based on the observed genital morphology, the possible functions of male and female genitalia are discussed in terms of sexual conflict. <i>Pterostichus glabripennis</i> Jedlička from China was removed from <i>Rhagadus</i> based on type examinations.</p>\u0000 </div>","PeriodicalId":54751,"journal":{"name":"Journal of Zoological Systematics and Evolutionary Research","volume":"2025 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/jzs/1776890","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144514523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Himalayan bent-toed geckos, <i>Cyrtodactylus</i> (Squamata: Gekkonidae), is an ideal group to study the phylogeography of the Himalayas due to its early origin, wide distribution, and ongoing diversification across its range. However, the specific impact of geological events on the diversification of Central Himalayan <i>Cyrtodactylus</i> has not been fully investigated. In this study, we sampled <i>Cyrtodactylus</i> from the Central Himalayan region and analyzed concatenated mitochondrial (NADH dehydrogenase 2, 1038 bp) and nuclear (phosducin [PDC], 393 bp, and recombination activating gene, 861 bp) DNA sequences totaling 2292 bp. We complemented these by the sequences from the Himalayan and the Indo-Burma regions. Phylogenetic analyses revealed that the <i>Cyrtodactylus</i> samples from the Himalayan region are grouped into four major groups: <i>C. lawderanus</i> group, <i>C. fasciolatus</i> group, <i>C. peguensis</i> group, and <i>C. khasiensis</i> group. The geckos sampled in this study from the Central Himalayas belonged to the <i>C. fasciolatus</i> and <i>C. khasiensis</i> groups. Our results indicate that <i>Cyrtodactylus</i> underwent radiation events from the early Eocene to the late Pleistocene, with a relatively constant rate of divergence but a significant deviation from a constant rate of lineage accumulation. These findings establish a complex relationship between gecko diversification and the orogenic process of the Himalayas, which created a diverse landscape, global climate changes that led to different environments, intermittent arid conditions, shifting south Asian monsoon patterns, and the evolution of rivers. These factors facilitated allopatric speciation in the Himalayan region. Our results support a west to east diversification pattern within the range of <i>Cyrtodactylus</i>.

We noninvasively collected a total of 77 fecal or tissue samples from various locations within Xinjiang, covering most of its range.

The genetic distance and genetic divergence between clades ranged from 1.21% to 9.25% and from 0.30 to 0.94, respectively. Our analysis of molecular variation (AMOVA) analysis also revealed that more than 70% of the variation was accounted for among the clades. The genetic differentiation between populations was positively corelated with geography distances (<i>r</i> = 0.472, <i>p</i> &lt; 0.01). We observed significant differences in genetic diversity among the various populations. The mismatch distribution analysis showed a multimodal distribution for all clades.

In conclusion, we genetically identified 10 matrilineal populations, which may represent subspecies of argali population, eight of which were in China.

In particular, data on the fine-scale evolution of the <i>uqcrfs1</i> in the context of speciation and adaptation are lacking. Eastern Mediterranean water frogs (genus <i>Pelophylax</i>) are an ideal model for studying such evolutionary processes at the molecular level, as they comprise several closely related lineages with different degrees of genetic and organismal divergence.
