Description

This frog is about the size of a fingernail: males measure and females about in snout–vent length. The snout is truncated. The tympanum is partially hidden under skin. Dorsal skin is slightly granular. The dorsum is pale green with diffuse yellow dots. The fingers and toes are yellow and partly webbed. Lower surfaces are unpigmented and the heart is visible through the parietal peritoneum. The iris is pale silver bronze. The male advertisement call is a single, monotone note, without amplitude modulation.
