Nanorana unculuanus (common names: Yunnan Asian frog) is a species of frog in the family Dicroglossidae.It is endemic to central and southern Yunnan, China, although it is expected to have wider distribution than currently known, possibly extending into Vietnam.[1] Its natural habitats are fast-flowing hill streams and riparian habitats in forests and grasslands, but also man-made habitats like roadside drainage ditches and ponds. It is a rare and secretive species that appears to be declining. It is currently threatened by collection for food and also by habitat loss.
Nanorana unculuanus are medium-sized frogs: males grow to a snout–vent length of about 76mm and females to 79mm. Tadpoles are up to 35mm in length.[2]
