Dorsal skin in males is smooth except for the few small warts on the upper flanks; in females there are small warts in the occipital region and the posterior part of the dorsum and larger warts on the flanks. The discoidal fold is well anterior to the groin. A pair of cloacal warts are present. The palmar tubercle is bifid (with inner lobe being the largest) and is much larger than the oval thenar tubercle. The fingers are long and slender. Fleshy fringes are present on the outer edge of the palm and finger IV. Discs on toes equal in size to those on fingers. Tip of toe V extends to distal edge of distal subarticular tubercle of toe IV.
In preservative the dorsum is pale to medium brown with dark marking consisting of interorbital bar, a W-shaped occipital mark, sacral chevron, suprainguinal spots, canthal-supratympanic stripe, and labial bars. In life, specimens had a green, tan, yellowish brown, or reddish brown dorsum with brown markings. Sides of the head, flanks and concealed regions of the limbs were yellowish.
