'''''Amolops chakrataensis''''', also known as the '''Dehradun stream frog'''<ref name=Frost/><ref name="Lost Amphibians of India"/> or '''Chakrata torrent frog''',<ref name="Venkataraman et al. 2013"/> is a species of [[frog]] [[endemic]] to [[India]]. It is only known from its [[Type locality (biology)|type locality]] near [[Chakrata]] in [[Uttarakhand]] (formerly [[Uttar Pradesh]]),<ref name=Frost/><ref name="Venkataraman et al. 2013"/> near the [[Tiger Falls]].<ref name="Lost Amphibians of India"/> It was [[species description|described]] based on a single specimen collected in 1985. After being "lost" for 25 years, the species was rediscovered in 2011 at its type locality, reflecting the lack of field work in the area.<ref name="Lost Amphibians of India"/>

==Description==
The [[holotype]] measures {{convert|55|mm|in|1|abbr=on}} in snout–vent length. The head is wider than it is long. The eyes are relatively small. The snout is obtusely pointed. The [[Tympanum (anatomy)|tympanum]] is visible and the supratympanic fold is distinct. The fingers are long and slender and have well-developed terminal discs. The toe discs are smaller than the fingers ones. The [[Dorsum (anatomy)|dorsum]] is slaty brown (or light green with dark minute spots<ref name="Lost Amphibians of India"/>). The sides are olive to dark green. A dark brown [[Canthus (herpetology)|canthal]] streak is bounded by white supratympanic fold. The upper lip is golden yellow and the lower one has brown patches. The limbs have brown crossbars. The ventral side is speckled with brown.<ref name="Venkataraman et al. 2013"/>

==Habitat and conservation==
''Amolops chakrataensis'' is a semi-aquatic species that occurs under rocks in stagnant pools near fast-flowing hill-streams in dense [[Cedrus deodara|deodar]] forest<ref name="Venkataraman et al. 2013"/> at an elevation of about {{convert|1000|-|1500|m|abbr=on}} [[above sea level]].<ref name=IUCN/> The eggs are laid on the leaves of aquatic plants.<ref name=IUCN/> The threats to this poorly-known species are unknown,<ref name=IUCN/> but the habitat near the Tiger Falls is highly degraded.<ref name="Lost Amphibians of India"/>
