Arndt’s Toothed Frog

Material: Three females, NGK-Nimba 0244, NGK-Nimba 0245, NGK-Nimba 0246, and two males, NGK-Nimba 0247 (Fig. 11A), NGK-Nimba 0248 .

Comments: Odontobatrachus arndti is a torrent-frog living in primary and slightly degraded forests, known from Mount Sangbé and Mounts Nimba (Barej et al. 2015; Channing and Rödel 2019). We found a few populations of O. arndti along cascades of streams in forested ravines edged by savannah (07°35.233’N, 008°25.190’W; 847 m asl). These frogs were found to be very abundant along a very torrent stream (07°34.652’N, 008°24.966’W; 716 m asl). In a lower part of the forest, an additional site was along a wide torrent stream with a gravel bottom and blocks of granite rock (07°33.121’N, 008°25.036’W; 422 m asl). The recorded males exhibited huge bright orange femoral glands. They measured 45.1‒52.5 mm (N = 8); the female SUL ranged from 43.5‒60.5 mm (N = 10), thus the sizes of both sexes are within the known range of the species (Barej et al. 2015). At all sites, the majority of frogs were close to the rocky streams, however, a few females perched on trees close to the streams. These records are the second for Ivory Coast.
