Crossotonotidae Moosa & Serène, 1981 and Palicidae Bouvier, 1898

Based on nearly identical foregut characters, species of both families are described here together. Crossotonotus spinipes (De Man, 1888) (Crossotonotidae) (Fig. 24 A, B); Pseudopalicus declivis Castro, 2000 (Fig. 24 C-F); Parapalicus clinodentatus Castro, 2000 and Micropalicus vietnamensis (Zarenkov, 1968) (last three species = Palicidae)

Ossicles I and II are inclined about 45° in the antero ventral direction. The unpaired propyloric ossicle (VI) is inclined about 10° in the posterior direction. The pectinal ossicle (VIII) is horseshoe-shaped with five accessory teeth. Ossicles “XVII–XXIII” are observed as a mixed ossicle. Ossicle XVIII has a comparatively large surface.
