We report on death-feigning behaviour in Chiromantis rufescens, Kassina lamottei, K. cochranae, Leptopelis hyloides, L. occidentalis, and L. macrotis from Tai National Park, Ivory Coast.

We describe the tadpole of Ptychadena aequiplicata (Werner, 1898) based on specimens from Tai National Park, Ivory Coast. Compared to other tadpoles of the genus it is unique by its bicoloured body, posterior part lighter than anterior one. Ptychadena aequiplicata is restricted to closed forest habitats. It has a reproductive behaviour unique to the genus. Clutches of numerous females were communally deposited on the forest floor, between leaves and small plants. Spawning sites were always situated at the edges of dried up ponds. Pre-hatching time was variable. Tadpoles still hatched two weeks after oviposition. In some specimens development continued in the large eggs up to Gosner stage 28. Developmental time from hatching to metamorphosis was less than two weeks. We regard this developmental mode as an adaptation to the surprisingly high desiccation risks of the forest ponds in Tai National Park.

Based on museum specimens, field records, and morphological, acoustical, and geographical analyses, we resurrect the species status of Kassina arboricola Perret, 1985 and redefine Kassina cochranae (Loveridge, 1941). Additionally, we describe Kassina schioetzi sp. nov., a hitherto overlooked species. This species differs from K. cochranae and K. arboricola in several morphological features, especially the shape of the male gular flap, and its very short, tonal advertisement call. All three species are associated with forest habitats. Kassina schioetzi lives in wooded parts of the Guinea savanna of Ivory Coast and a single mountainous locality in eastern Guinea. Kassina cochranae occurs from western Ivory Coast to eastern Sierra Leone; K. arboricola occurs from Ghana to western Ivory Coast. At two localities, K. schioetzi occurs in syntopy with K. arboricola, and at another locality with K. cochranae. A key to all West African Kassina species is provided.
