Mantidactylus zolitschka Glaw and Vences 2004

Mantidactylus zolitschka Oral disc: Oral configuration is described and illustrated in Randrianiaina et al. (2011a) and reproduced here (Fig. 1). SEM micrographs show the M-shaped upper jaw sheath, keratinized and finely serrated (Fig. 7A). The lower jaw sheath is V-shaped, poorly keratinized, and marginally serrated (Fig. 7B). Details of labial teeth could not be observed. Buccal floor (Fig. 7B, C): Four pairs of tall, conical infra-labial papillae overlapping each other. Buccal floor arena delimited by two long, thick crests formed of about 15 transverse ruffled ridges closely spaced (120–250 µm long, 100–340 µm wide). Glottis not visible. Buccal roof (Fig. 7D): Prenarial arena with a wide inverted-V crest with smooth margin. Internal nares with a long, conical, pustulated papilla at the anterolateral edge. Central area of buccal roof arena smooth, with low pustulations scattered.
