A forest species found throughout West Africa as far as Uganda.

Life History, Abundance, Activity, and Special Behaviors

Males call from branches in dense forest. The voice is very quiet and inconspicuous and consists of two motifs: a series of clicks, varying greatly in number but with a rate of about 5 per second, and a buzzing. The voices of frogs from Uganda were noted as being similar to those from West Africa.

Malcolm Coe (1967) observed and described foam-nest building in Chiromantis rufescens as communal between a single female and at least three males. The nests were large enough to accommodate 200 eggs. This may be particular to this C. rufescens as previous observations of other Chiromantis species (such as C. petersii and C. xerampelina) created foam nests only in pairs.

Foam nests with eggs always occur above water, often above very small, temporary water bodies such as elephant footprints. After 5 to 8 days the tadpoles wriggle their way through the hardened shell of the nest and drop into the water (Schiøtz 1999).

Larva
The tadpoles are uniform grey and have a round body and a rather short tail. The tooth formula is 1,4+4/1+1,2 or 1,3+3/1+1,2 (Schiøtz 1999).
