Type species.

Hexamitodera (Sulcognatha) blairi (Bentanachs & Vives, 2009) comb. n.

Description.

Head and mandible enlarged in both sexes; gena acutely produced; clypeus strongly concave, very short; labrum reduced and not visible from dorsal view; mandible basally broadened, in male conspicuously, and distal half antero-laterally of mandible in both sexes with prominently developed concavity (Fig. 2A; 3D). Apex of mesosternal process concealed by metasternum; antenna and tibia with chromatic sexual dimorphism.

Etymology.

The new subgenus name is a combination of the Latin word sulcus (meaning, “furrow”) and the Greek word gnathus (meaning, “jaw”), and is a reference to the deep antero-lateral furrow in the mandible of both genders. The name is feminine.
