  "abstract": "The Dehradun Stream Frog, Amolops chakrataensis, is a Critically Endangered stream-dwelling amphibian endemic to Uttarakhand in the western Himalayas of India and the species was previously known only from a single holotype collected in 1985. Despite repeated surveys, the species remained undetected for more than four decades, raising concerns that it went extinct. Here, we report the rediscovery of A. chakrataensis from the Maneri landscape, Uttarakhand, approximately 65 km on a straight-line east of the type locality. We confirmed the species identity using an integrative taxonomic approach combining morphological comparisons with the holotype, and we sequenced the mitochondrial 16S rRNA DNA gene fragment. Our analyses recovered A. chakrataensis as a distinct clade. Extensive field surveys covering 14 sites and 424 person-hours detected only two individuals, highlighting the rarity of the species. Using environmental characteristics of the three known localities, we developed a habitat envelope that identified additional priority areas for future surveys and potential conservation management. Our findings confirm the continued persistence of A. chakrataensis, provide the first molecular reference for the species, extend its known distribution, and establish an important foundation for future monitoring and conservation planning in the western Himalayas.",
