Description

Ptychadena retropunctata (Angel, 1949)

Nimba Grass Frog

Material: Two males, NGK-Nimba 0060, NGK-Nimba 0061, and two females, NGK-Nimba 0062, NGK-Nimba 0063 (Fig. 14A).

Comments: Five P. retropunctata were recorded on a high plateau with predominantly grassy mountain pastures and herbaceous vegetation (07°35.453’N, 008°24.957’W; 843 m asl). The SULs of males varied from 28.0– 30.5 mm (N = 3), while two females measured 29.0 and 37.5 mm. Whereas four frogs were rust-colored, a female had a deep brown dorsum. In contrast to Rödel (2000) and Channing and Rödel (2019), who describe a white venter, our specimens had a yellow venter. The species was described previously from Mounts Nimba (Angel 1949). Further records became known only from a few montane localities in southeastern Guinea (summarized in Rödel et al. 2004), the Loma Mountains in Sierra Leone (Lamotte 1971), northern Guinea (Hillers et al. 2006), and southeastern Senegal (Monasterio et al. 2016). This is the first country record for P. retropunctata in Ivory Coast.
