Rusty Forest Tree Frog

Males measure 33–35 mm (1.3–1.4 in) (30–36 mm according to Rödel) and females 42–48 mm (1.7–1.9 in) in snout–vent length. The dorsum is smooth and brown with a darker pattern, normally consisting of an occipital bar and an 'n'-shaped dorsal marking. Also a green specimen without a dark lateral stripe has been photographed. This suggests that a green phase may be present in this species. Indeed, the specific name viridis suggests that the type specimen had been green in life. Males have dark, almost uniform black throats. There is no webbing on hands and the webbing in feet is reduced.

According to the International Union for Conservation of Nature (IUCN), Leptopelis viridis is recorded in the following countries (listed from west to east): Senegal, the Gambia, Guinea-Bissau, Guinea, Sierra Leone, Liberia, Ivory Coast, Burkina Faso, Ghana, Togo, Benin, Niger, Nigeria, Cameroon, and the Democratic Republic of the Congo. Further, it is expected to occur Mali, Chad, the Central African Republic, Sudan, and South Sudan.
