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 noninvasively collected a total of 77 fecal or tissue samples from various locations within Xinjiang, covering most of its range. Consequently, we identified 22 distinct haplotypic sequences for <i>Cytb</i> (1140 bp) and 36 for CR (1107–1260 bp).
