These species, characterized by cryptic diversity and narrow ecological niches, face threats from habitat loss and climate change. We integrated population genetics and ecological niche modeling (ENM) to assess their genetic diversity, population structure, and future habitat suitability. Using cytochrome b and <i>MC1R</i> gene sequences (1248 bp, 75 sequences), we found high haplotype diversity (e.g., <i>D. schaekeli</i>, Hd = 0.985) and evidence of historical population expansion (raggedness = 0.0052, <i>τ</i> = 34.204), suggesting refugial persistence in the Hyrcanian forests and Alborz Mountains. <i>Darevskia steineri</i> showed low diversity and high gene flow indicating demographic stability. Phylogenetic analyses confirmed species distinctiveness but revealed intra-lineage structuring in the <i>Persiodarevskia</i> group. Maxent-based ENM, using WorldClim data, project significant habitat contractions and elevational shifts by 2070 across four climate scenarios, with <i>D. kopetdaghica</i> and <i>D. kamii</i> most vulnerable due to restricted ranges. Temperature extremes and precipitation seasonality emerged as key climate drivers. By combining genetic distinctiveness with ENM, we identify conservation priorities, emphasizing microrefugia preservation and range-edge monitoring.

The ovaries contain meiotic cells, suggesting that automictic thelytoky occurs in this species. <i>D. parthenogenetica</i> sp. nov. colonised areas west of the ancestral sexual species <i>D. hungarica</i>, especially the Pannonian region; the distribution areas of these species show minimal overlap. The distribution pattern of <i>D. parthenogenetica</i> sp. nov. suggests that the obligate thelytoky in this species originated through geographic thelytoky. <i>D. parthenogenetica</i> sp. nov. has been found in a significantly larger variety of habitats than <i>D. hungarica</i>, including agroecosystems. Therefore, the parthenogenesis of <i>D. parthenogenetica</i> sp. nov. is associated with the ability to populate even habitats without tree or bush cover, often disturbed, which is unfavourable for other <i>Dysdera</i> species. According to the analysis of selected nuclear (ITS2) and mitochondrial markers (COI), <i>D. parthenogenetica</i> sp. nov. showed low genetic diversity (single COI haplotype and two closely related ITS2 haplotypes) in contrast to the ancestral <i>D. hungarica</i>.

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.

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>.

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).
