HABITAT. — During the dry season, the species can be found under stones on river banks, whereas they breed in savannah ponds during the rainy season (Rödel 2000). This frog occurs in open landscapes, savannah-forest ecotone and the degraded part of rainforest (Hughes 1988; Konan et al. 2016; Onadeko 2016). Some authors also list more arid habitats (Amiet 1974). It is widely distributed in West Africa and in a large part of sub-Saharan Africa from Senegal to South Africa (Rödel 2000; Channing 2001; Channing & Howell 2006).
