HABITATS AND DISTRIBUTION. — Originally, the species was collected in Missahohé (Kpalimé), forest area of Togo (Ahl 1931). This species is endemic to the Togo-Ghana forest zone according to SchiØtz (1999), Rödel & Agyei (2003) and Leaché et al. (2006). It is very abundant throughout the forest area of Togo. It occurs likewise in savannahs associated with forest areas near watercourses or pools. Males are usually sitting on grasses ( Panicum sp.) at heights of 1.5 to 3 m above the ground, usually above water. This species was observed from the lower Missahohé Mountain (Yo, Agome) to Yégué in Adélé. The northernmost record in Togo is from Malfakassa valley (9°10’45.54”N, 0°58’16.69”E).
