Small frog with relatively large head. Males attain a snout-vent length of up to 34,7mm, whereas females grow up to 38 mm. The eyes are large and have a vertical slit-shaped pupil. Limbs, fingers and toes are relatively long. There are three metacarpal tubercles. The skin is fairly smooth and shiny. Some larger warts are present along the sides of the back. The coloration is very variable. Usually there are dark green to black spots of variable size and shape on a golden-greenish background. Not seldom there is a black triangle present on the head behind the eyes. The underside is white. There is no clear sexual dimorphism. (Noellert and Noellert 1992).
