[2] It is known with certainty only from its neotype locality at the Dawna Range in Myanmar, near the border to Thailand,[1][2] but molecular data suggest that it is present in northeastern India and in peninsular Thailand too, while records from China refer to other species.

[2] Adult females measure 89–97 mm (3.5–3.8 in) in snout–vent length (neotype and a referred specimen); males are presumably much smaller.

The tympanum is round and distinct; the supratympanic fold is weak.

[3] Little precise information on ecological requirements of this species is available.

It probably occurs near fast-flowing rivers and streams in montane tropical forests.
