Abstract: Two new species of Cyrtodactylus from the khasiensis group are described using morphological characters supported by molecular analyses based on the mitochondrial ND2 gene. Cyrtodactylus makwanpurgadhiensis sp. nov. and C. chure sp. nov. from the Siwalik Mountains in central Nepal are at least 11.2% divergent from other Nepalese congeners and 16.7% from each other and can be distinguished by a combination of morphometric and meristic traits. The description of two new species from the Siwalik Mountains underscores the conservation significance of this region, a relatively young, dry, and geologically unstable range of the Himalayan orogen. Despite serving as a border between the lowland (Terai) and Himalayan range, it remains underrepresented in both biodiversity assessments and conservation planning in Nepal. Our findings suggest the need for a robust and targeted species research program and to prioritise this landscape for conservation actions.
