Rounded canthus rostralis with a concave loreal region. Rounded nostrils have a lateral skin flap and lie closer to the eyes than to the tip of the snout. Interorbital space convex. Eyes have indistinct pupils. Rounded tympanum which is barely distinct. Distinct supratympanic fold which extends from the eye to above the shoulder. Pineal ocellus lies between the anterior borders of the eyes. Lacks a vomerine ridge. Tongue large, cordate, emarginate, and lacks median lingual process. Rictal gland is present along with two smaller glands posterior to mouth. Robust arms, shorter than hands. Fingers are thin, short, lack dermal fringe and webbing, with tips that are rounded but not expanded. Finger I is shorter than Finger II. Prominent single rounded subarticular tubercles are present on all fingers, but supernumerary tubercles are absent. Prepollex is distinct and oval-shaped. Palmar tubercle indistinct. Toes are long, thin, and rounded at the tips, but lack expanded discs. Toes have basal webbing. Toe V lacks dermal fringe. Subarticular tubercles are simple, oval-shaped, and prominent on toes. Prominent inner metatarsal tubercle, small rounded outer metatarsal tubercle. Inner tarsal ridge is flattened. Supernumerary tubercles and tarsal tubercle are absent. Dorsal and lateral surfaces are smooth, except for the posterior of the dorsum which bears glandular warts. Ventral surfaces have dense glandular warts. Dorsal and ventral surfaces of the thigh are shagreened. Rictal gland is present along with two smaller glands posterior to mouth. Males have single patch of small transparent whitish to grayish nuptial spines on the prepollex and finger I, extending up to the subarticular tubercle (Ohler et al. 2009).
Grayish beige dorsum with with light orange vertebral stripe and darker greyish beige longitudinal stripes. Black canthal stripe continues along tympanic fold. The loreal region, tympanic region and supratympanic fold are all dark grayish brown. Light laterodorsal bands (no folds). Dark gray "Fejervaryan" line is present.
