Figure 7; CT-scan image of the dorsal side of the humerus of Petropedetes johnstoni (A male, ZFMK87709) and P. newtonii (B male, MNCN 48728). Note the differences in the development and extension of the bone crest.
Figure 9; Ventral view of the right forelimb of Petropedetes newtonii (adult male, MNCN 48728). Arrows point to the dorsal spine on the distal edge of the metacarpal of Finger I and keratinised spicules along the skin surface of the upper arm and labial commissure.

Figure 5; Thenar tubercle of males of Petropedetes newtonii (A male, MNCN 48728) and P. johnstoni (B male, ZFMK 87709). Note the different shape and size and the presence of a dorsal spine on the distal edge of the metacarpal of Finger I in P. newtonii.
Figure 6; CT-scan image of the dorsal side of the hands of Petropedetes johnstoni (A male, ZFMK 87709) and P. newtonii (B male, MNCN 48728). No traces of metacarpal spines are detected in P. johnstoni.
