Amolops cf. afghanus
Range
Amolops afghanus: Myanmar (Kachin); the source does not name Nepal
Size
Females about 8cm; males about 5cm
Amolops afghanus, the Kachin torrent frog, was described by Albert Gunther in 1858, and the name comes from his report of Afghanistan, though specimens were later collected in Kachin, Myanmar. It is a medium-sized, sometimes slender frog, about 8cm in females and 5cm in males, dark green with a dark mottled back and a light underside (Wikipedia, general species account).
The cf. in the Nepal name means the identification is not confirmed. The source treats the species as native to Myanmar only and does not name Nepal, so its place on the Nepal list should be checked (Wikipedia, general species account).
