Description

Batrachuperus pinchonii males measure 181-204 mm in total length, females 150-186 mm. Head is flat, and longer than wide. Snout rounded and short. Adult has no or trace remnant of gills. Vomerine teeth short, 4-6 teeth on each side in the shape of / , with a gap between the two sides. Body cylindrical, covered with smooth skin. Just behind the eyes and outside of the apparent jugular fold, there is a groove going towards the ventral side. Around 12 costal grooves are present. Tips of forelimb and hindlimb toes overlap at the tip when adpressed, or are separated by 1-2 costal grooves in length. There are four unwebbed toes on each forelimb and four unwebbed toes on each hindlimb. Tail comprises half of the salamander's total length or longer, with a cylindrical base but flattening out towards the tip. Tail fin fold obvious, rounded at the tip (Fei and Ye 2001).

Body color varies geographically. Batrachuperus pinchonii is generally brown, olive, or pastel yellow in color, with variable patterning as well. Some specimens have gray cloud-like patterns that run along the dorsum to the side of the tail (Fei and Ye 2001).

Batrachuperus pinchonii larvae have a pair of tri-forked featherlike gills, and a larger tail fin fold. When the total length reaches 80 mm, the gills will disappear (Fei and Ye 2001).

The chromosome number for this species is 2n=66 (Kuro-o et al. 1998).
