DESCRIPTION. — 49 specimens examined.Size of vouchers (SVL 23.2- 31.3 for males and 28.8-30.9 mm for females) corresponding the values of Lampert (2001). In life, specimens with a yellowish back framed by dark lateral bands with narrow yellow edges, extending from the eyes back to above the legs (Fig. 4E). Sometimes, back showing a brown and greyish pattern with very small dark spots. Dorsal coloration lighter and with less contrasting pattern at night. HABITAT. — Hyperolius nitidulus was found on grasses and bushes in floodplains, in swampy valleys and farmland such as maize and paddy fields, plantain plantations and vegetable gardens. It was also found on plants above water at nearby ponds and rivers. This species inhabits shrublands, grasslands and wetlands in the Guinean and Sudanian savannahs, from central Guinea to Cameroon (Lamotte 1967b; Rödel 2000; Rödel et al. 2010a).
