[2] The specific name wenxianensis refers to its type locality, Wen County, Gansu (Chinese: 文县; pinyin: Wénxiàn).

Its body has dorsal tubercles extending from the occiput and temporal regions to the back and tail base, but are lacking on the forelimb and thigh.

It counts with 6–8 pre-cloacal pores in a continuous series in males, and a tail generally with two cloacal spurs on each side.

[1][2] Snout–vent length varied between 52 and 59 mm (2.0 and 2.3 in) among the males and females in the type series.

[2] The type series originates from the south slope of the west Qin Mountains at an elevation of 905 m (2,969 ft) above sea level.
