Odontobatrachus arndti Barej, Schmitz, Penner, Doumbia, Sandberger-Loua, Emmrich, Adeba, and Rödel, 2015

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.
