Mantidactylus ambony

Oral disc: Oral configuration is described and illustrated in Randrianiaina et al. (2011a; as M. ambreensis), and reproduced here (Fig. 1). SEM micrographs show the strong serration of the upper jaw sheath (Fig. 3A).

Buccal floor (Fig. 3B): Almost identical to M. ambreensis configuration; crests of the buccal floor with slightly smaller ruffled ridges (100–155 µm long, 23–76 µm wide).

Buccal roof (Fig. 3C): Features of the prenarial, narial, and dorsal velum regions unfortunately could not be observed. Other features as in M. ambreensis, except less numerous buccal roof arena papillae (about 20 on each side).
