A small (26–31 mm) frog from the dense forests in Cameroun. Colour bright green, dorsum with small white asperities. Hidden parts of limbs turquoise green. Males with a large gular flap and a reduced gular sac. Ventrum translucent so that the inner organs are visible.
Voice. – Apparently not gregarious during breeding. The males sit far from each other as do Leptopelis. The voice is a metallic “toc”, repeated 5–6 times.

Life History, Abundance, Activity, and Special Behaviors
Development. – The eggs, 40–50 in an egg mass with transparent jelly, are deposited about 1.5 metres above water near small streams. Apparently the female guards the eggs and assists the larvae in breaking free of the jelly. The jelly does not seem to disintegrate as in Hyperolius, and the tadpoles orientate themselves in it with the head up. A batch in captivity spent 3 weeks in the jelly apparently living on their yolk. The next stage is spent in water, where the tadpoles are plant-eaters. They have a tooth formula of 1,1+1/3 which is different from that of Hyperolius. The largest tadpoles are 29 mm.
