DESCRIPTION. — 76 specimens examined. Newly collected females 31.7-49.5 mm SVL, males 33.2-38.7 mm SVL. Smaller than Lamotte & Ohler (1997) vouchers: males 38-51 mm and females 40- 61 mm. Specimens with a pointed snout, distinct and long limbs. Webbing formula: I 1 - 2 II 1 - 2 ½ III 1 - 3 IV 2 ½ - 1 V. Presence of supernumerary tubercles on the toes III and IV. Three pairs of dorsal ridges, including a pair of sacral ridges, a pair of ridges visible on the head between the eyes and ending in the lower part of the back, a second pair of ridges from behind the eyes to the same level as the median ridges and a third pair of ridges visible approximately above the tympanum, near the eye to the level of the other two pairs. The second and third pairs of ridges discontinuous in some specimens. A lateral ridge usually absent or only present as a short row of discontinuous light warts. For further detailed descriptions see Lamotte & Ohler (1997) and Rödel (2000).
Dorsum a grey to pale brown with numerous tiny dark brown to black spots, restricted to the longitudinal ridges. Light reddish or yellow vertebral lines may be present or absent.
HABITAT. — We encountered this species under grasses at the edges of ponds and on river banks. It was also found in paddy fields. In the dry season, we collected P. bibroni under rocks, deadwood and accumulated dry grass around ponds. The species was found in dry and wet savannah habitats, intermittent freshwater wetlands, rural gardens, heavily degraded forests (agricultural areas), channels and ditches (Rödel 2000). It is a common species, widely distributed in West Africa (Lamotte & Ohler 1997; Nago et al. 2006; Segniagbeto et al. 2007; Mohneke et al. 2011; Onadeko 2016; Sánchez-Vialas et al. 2017).
