description
The head-torso length is up to 18 millimeters. The head is broad, flattened and triangular. The forehead is as long as the diameter of the eye, with a sharp canthus rostralis . The nostril is closer to the tip of the forehead than to the eye. The interorbital space is much wider than an upper eyelid. There are only four fingers and four toes, the first and fourth of which are very small. First and fourth toes are even only stubby. The third finger is twice as long as the second. The fourth toe is almost three times as long as the third. The subarticular cusps are indistinct. There is a rounded, lateral metatarsal cusp. The tibiotarsal joint extends to the eye when the hind leg is laid forward to the body. The skin is very finely chagrined. Above the anus there is a triangular field with flat, wart-like elevations. The top is yellowish brown with small dark spots. The underside is whitish. From the tip of the forehead to the eye, a black stripe stretches under the canthus rostralis on each side.
