Description

A small species of frog reaching up to 3.5 cm in body length. It has a brown-grey back, with darker patches and an indistinct, orange longitudinal stripe along the middle. There is sometimes a small, pale orange-white stripe from the edge of the mouth to the arm. The belly is light grey with white specks, and the male has a light grey throat. The under-surfaces of the arms and legs are pale pink. The pupil is horizontal, and the iris is gold. There is a small orange patch on the back of each thigh. Fingers are unwebbed and toes are three-quarters webbed, both without discs. The parotoid glands, glands in the groin, and glands on the lower back are large and orange or pale orange-brown.

Breeding Biology

Eggs, tadpoles, and development time are unknown, but are likely to be similar to those of other Uperoleia species. The eggs are laid near rivers. Breeds during summer in the wet season.
