Mantidactylus femoralis

Oral disc: Oral configuration is described and illustrated in Randrianiaina et al. (2011a % and reproduced here ( Fig. 1 %. SEM micrographs show labial teeth short, with wide sheath and head with four to eight long, distal cusps ( Fig. 4A %. Upper jaw finely serrated and lower jaw sheath º-shaped, poorly keratinized, and marginally serrated ( Fig. 4B %.

&uccal floor ( Fig. 4B, C %: Four pairs of short, conical infra-labial papillae not overlapping each other. Buccal floor arena crests formed of approximately 15 transverse ruffled ridges closely spaced (45–140 µm long, 20–50 µm wide%. Gloưis fully covered.

&uccal roof ( Fig. 4D %: Prenarial arena with a wide inverted-º crest with a mostly smooth margin. Internal nares with a long, conical papilla at the anterolateral edge; posterior margin partially concealed by a short, wide, triangular postnarial arena papilla anteriorly directed. Median ridge very short, triangular, and with smooth free margin. Buccal roof arena delimited by two slightly convergent crests formed of c. 30 closely spaced papillae. Central area of buccal roof arena smooth. Glandular zone not evident in micrographs.
