A medium-sized montane Hyperolius (males 22–26 mm, females 25–36 mm) from central Africa with a pattern in brown and green.

Colour pattern very variable, but does not fall into a juvenile and a female phase. Dorsum brown to green, the green specimens often with diffuse darker rounded spots, the brown-backed specimens often with irregular black spots surrounded by bright green. A black canthal line always present. Some of the green-backed specimens have an irregular light lateral line. The brown-backed specimens have a very irregular black lateral line. Ventrum and feet yellow to reddish. Throat of males yellow. Pupil horizontal.

This is a most variable form from the central highlands. It bears a close resemblance to H. lateralis in voice and habitat preference, and some specimens may be impossible to identify. H. lateralis generally occurs at lower altitudes.
