The specific epithet is named for the type locality, Mengding Township. Diagnosis. Morphologically, A. mendingensis sp. nov. assigns to the A. monticola group by having the combination of smooth dorsal skin, dorsolateral fold, and the side of head dark with a light-colored upper lip stripe extending to the axilla (Stuart et al. 2010).

Description of holotype. Adult male (SVL 39.7 mm); head longer (HL 13.7 mm) than wide (HW 12.6 mm); snout obtusely pointed, projecting beyond margin of lower jaw in ventral view, rounded in profile; canthus rostralis distinct, nearly straight; loreal region sloping, concave; nostrils oval, lateral, slightly protuberant, slightly closer to eye than snout tip; internarial distance (IND 4.7 mm) greater than interorbital distance (IOD 3.6 mm); upper eyelid width (UEW 3.4 mm) slightly narrower than interorbital space; pineal spot absent; pupil oval, horizontal; tympanum distinct, rounded, less than half eye diameter; supratympanic fold indistinct; vomerine teeth in two oblique rows between choanae, closer to each other than choanae; choanae oval; tongue attached anteriorly, cordiform, deeply notched posteriorly; vocal sac opening on floor of mouth at each corner; two external subgular vocal sacs.
