DESCRIPTION. — 23 specimens examined. Frogs with SVL from 17.4-21.2 mm in 23 males, smaller than A. vittiger . Specimens with a yellow or a very intense silvery white back ( Fig. 4C View FIG ), often with a fine brown vertebral line, at least in the posterior part of the back. Laterally, a less distinct dark band from the snout to the groin. On the shank, presence of dark brown longitudinal bands.
HABITAT. — This species was usually collected on grass at a height not exceeding 0.5-1.5 m ( Fig. 2D View FIG ). During the day, resting animals can be found above water on plants ( Lamotte & Xavier 1981; SchiØtz 1967, 1999). Males call at night, usually on high grasses, a few meters from the pond edges ( Rödel et al. 2006). Afrixalus weidholzi is a common species which has a wide range in West African drier savannah zones ( Rödel 2000; Padial et al. 2013) and occurs occasionally in the same habitats as A. vittiger .
