Description
A large Afrixalus (males 27–31 mm, females 32–35 mm) from bushland from Angola to Uganda, with a pattern in light and dark brown, normally with a rectangular dark dorsal spot and a narrow extension of the light dorsal pattern to the anus. Males have small, scattered and inconspicuous asperities on dorsal surfaces of head, body and limbs. Tibia with light upper side.
Most populations have a very constant pattern, but Laurent mentions that some populations vary considerably.

Voice is a typical Afrixalus call consisting of a series of clicks. In a recording from Uganda these were made at a rate of 18–20 per second; in a recording from central R. D. Congo, at 20–30 per second; in both cases with an indistinct frequency–intensity maximum at 2500–3000 cps.
