Skin. Dorsal surface of head and body smooth; supratympanic fold extending from posterior edge of eye to axilla; upper lips, around tympanum and upper eyelid with small spines; flanks with some tubercles; surrounding of cloaca with tubercles; dorsolateral folds present; and ventral surface smooth.
Colouration in life.

Distribution
In Vietnam, this species has been recorded from Lao Cai and Ha Giang provinces ( Nguyen et al. 2009, Nguyen et al. 2016). Our new record in Son La Province is approximately 70 km and 150 km distant from Lao Cai and Ha Giang provinces, respectively. Elsewhere, this species is known from China ( Frost 2019).
Ecology
The specimens were found on the edge of streams, between 19:00 and 21:30. The surrounding habitat was secondary forest, composed of larger hardwoods and shrubs.
