The taxonomic status of Parandrocephalus blairi Bentanachs & Vives 2009 and a new subgenus of Hexamitodera Heller, 1896, with notes on convergent evolution and secondary sexual characters Author Perger, Robert text ZooKeys 2013 293 77 89 http://dx.doi.org/10.3897/zookeys.293.5133 journal article http://dx.doi.org/10.3897/zookeys.293.5133 1313-2970-293-77 Sulcognatha Perger subgen. n. Fig. 1C, D 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. Included species. This subgenus includes so far only the type species.
