; although the largest specimen was a female, males and females do not differ in size overall. The body is slender and the head is narrower than the body. The snout is rounded. The tympanum is distinct. The fingers and toes have no webbing. Skin is dorsally slightly granular. The dorsal background color is black. There are bright yellow dorsolateral and labial lines as well as mid-dorsal spots and/or dots. The limbs are brown with black or black with bright yellow markings. The ventral surfaces are light grey to light brown with black marbling. The male advertisement call is a series of indistinctly pulsed, upward modulated notes. The dominant frequency is about 2.7–3.2 kHz.
