DESCRIPTION. — 71 specimens examined. Some of these specimens slightly larger than others. Male’s body size between 20.9-27.3 mm while female’s size 21.3-26.7 mm. Agreeing with Pickersgill (2007), indicating males body size from 21-26 mm and 22-28 mm for females. Skin asperities, typical for the genus, present on dorsum but also on belly, prominent on tarsus and feet in males. On back of all specimens, seven vertical distinct bands, four brown separated by three whitish (Fig. 4B). Ventral skin colour whitish.
HABITAT. — We observed A. vittiger in floodplains and swampy valleys. The species is present in protected areas such as Arly National Park, W National Park, Comoé-Léraba Forest and Deux Balés National Park. In Koubri, Pabré and Loumbila, the species was found in paddy fields, around ponds on grasses and plants surfacing water (Fig. 2C, D, F). It is a common savannah species which has a large distribution range in West Africa (Rödel 2000; Leaché et al. 2006; Nago et al. 2006; Segniagbeto et al. 2007). This species has often been confused with its congener A. fulvovittatus. The two species partly overlap in the forest-savannah ecotone of West Africa. However, Afrixalus fulvovittatus occurs in heavily degraded forest areas whereas A. vittiger mostly lives in savannah areas (Pickersgill 2007; Rödel & Glos 2019).
