A Hyperolius from the savanna at high altitude in Tanzania, with the males minute (12-17 mm), and the females medium-sized (18-24 mm). Dorsum brown with light canthal and dorsolateral lines. Gular flap smooth and very large. A few black spinosities present in front of the gular flap near the tip of the jaw. Pupil horizontal. Some females have broad light canthal, and irregular dorsolateral, stripes, and spots on dorsum.

The most remarkable feature of this species is the minute size of the males which are no larger than newly metamorphosed H. pictus, a sympatric species. The species is not well known and in some respects resembles H. spinigularis. It is possible they belong to the same complex.
