Extended diagnosis

This species is assigned to the Amolops mantzorum species group on the basis of the absence of a dorsolateral fold and the absence of circum-marginal groove on the disc of the first finger. It is distinguishable from other members of this species group by a combination of the following morphological characters: size small (SVL 29.7–38.3 mm in adult males and 38.5–51.1 mm in adult females); head moderate large, longer than wide (HL / SVL 0.33–0.37 in males and 0.31–0.35 in females, HW / SVL 0.28–0.33 in males and 0.26–0.32 in females); tympanum distinct, small (TD / HL 0.10–0.23 in males and 0.09–0.27 in females); pineal spot present; pupil oval, horizontal; vomerine teeth absent or weakly developed; vocal sac absent in males; fore-limbs robust (FLL / SVL 0.70–0.87 in males and 0.67–0.85 in females), relative finger lengths I < II < IV < III; hind-limbs long (HLL / SVL 1.79–2.09 in males and 1.70–2.00 in females), relative toe length I < II < III < V < IV; dorsal skin smooth, with a few flattened tubercles on flanks and posterior surface of dorsum; supratympanic fold absent or weakly developed; true dorsolateral folds absent, but dorsolateral glandular folds distinct; circummarginal groove on tip of first finger absent; inner metatarsal tubercle small; outer metatarsal tubercle absent; nuptial pad present on finger I of adult males. Colour of dorsal surface from nearly uniform green to mostly brown, flanks mostly green, dark bars on dorsal limbs distinct or indistinct.
