Species.

14 species and subspecies; length 12-19 mm.

Species in the genus Homonyx are elongate, parallel-sided, subcylindrical, and dark-colored beetles. They strongly resemble the allied genus Parhomonyx but can be separated based on the form of the mandibles (bidentate in Homonyx and broadly rounded with one apical tooth in Parhomonyx ), the apex of the metatibia (with many spinules in Parhomonyx and biemarginate in Homonyx ), and the feathery fringe of setae at the apex of the elytra (exposed in Parhomonyx ; hidden in Homonyx ). These genera share additional characters: prosternal process short (well-developed in H. planicostatus ); mesosternum not produced beyond the mesometasternal suture; pronotum with bead complete apically, laterally, and basally; claws simple; lateral set of setae on apical edge of 3rd metatarsomere of unequal length and width (versus equal in length and width in Catoclastus ).

Species in the genus are distributed in Argentina, Brazil, Bolivia, Ecuador, Uruguay, and Peru. Soula (2010a) provides the most current treatment of species in the genus, but did not include a key for identification. Larvae, sister-group relationships and natural history are poorly known for species in the genus.
