Body small and elongate, SVL 52.0 mm; head length (HL 17.6 mm) larger than width (HW 15.7 mm); snout slightly sharp, canthus rostralis distinct, loreal region slightly oblique; nostril at tip of snout, internarial distance (IND 4.3 mm) narrower than interorbital distance (IOD 9.3 mm); tympanum (TD 3.1 mm) rounded, slightly larger than half eye diameter (ED 5.4 mm), separated from eye by 1.6 mm; pupil transverse, eye diameter larger than half snout length (SL 7.7 mm). Vomerine teeth present; tongue attached anteriorly, deeply notched posteriorly.

Forearm and hand length (FHL 17.8 mm) no more than half SVL; relative length of fingers I < II < IV < III; tips of all fingers expanded into discs with transverse grooves, disc of first finger small, disc of third finger largest, its width nearly equal to tympanum; webbing formula I 1-1 II 0-1 III 1-1/2 IV; subarticular tubercles distinct, formula 1, 1, 2, 2; rows of tubercles present on palms; inner metacarpal tubercle large and flat, outer metacarpal tubercle absent.
