The following is from the original description of the type, a single female specimen, by Boulenger (1905):

Vomerine teeth in two short transverse series close to the inner front edges of the choanae. Head once and a half diameter of the orbit, very strongly projecting beyond the mouth; canthus rostraiis feebly marked; loreal region slightly concave; nostril midway between the eye and the end of the snont; interorbital space narrower than the upper eyelid; tympanum distinct, three fourths the diameter of the eye. Fingers moderate, obtusely pointed, first not extending quite as far as second; toes very long and slender, barely half webbed; subarticular tubercles moderate; a small, oval, inner metatarsal tubercle. The tibio-tarsal articulation reaches far beyond the tip of the snout. Foot nearly two thirds the length of head and body, tibia rather more than two thirds. Back with eight glandular longitudinal folds, outer strongest; a glandular fold from beneath the eye to the shoulder. Greyish olive above, with black spots; limbs with regular blackish cross-bars; a black band on the side of the head, passing through the eye and covering the temple; a vertebral stripe, the outer glandular fold, and a streak on the upper lip, from the end of the snout to the shoulder, yellowish white; lower parts white, edge of lower jaw and side of throat black.
