Genus Pereirabolbus Martínez, 1976

( Figs. 38 –42, 49, 51, 54)

Pereirabolbus Martínez, 1976: 539 (as a subgenus of Bolborhinum ). Type species: Bolboceras castaneum Klug, 1845 by original designation. Gender: masculine.

Diagnosis. The following characters will separate Pereirabolbus from all other South American Bolboceratini: head in the males and females without horns or tubercles ( Figs. 38 –42). Antennal club circular ( Fig. 49). Pronotum evenly rounded or with weak carinae and depressions. Scutellum triangular. Elytron with basal margin, with 7 striae between medial suture and humeral swelling. Prosternal process absent. Mesocoxae subcontiguous. Metasternum pyriform, bulbous, with long, median metasternal carina; metasternal anteriorly truncate, not distinctly convex between mesocoxae. Protibial spur not extending to apex of protibia. Mesotibia and metatibia with transverse ridge well separated from the distal apex, not subapical. Male genitalia: similar to Bolborhinum ; aedeagus small, simple in structure, arcuate; parameres short, basally membranous, with apex narrow distally, obtuse (Fig. 54).

Remark. The elevation of Pereirabolbus to the generic level creates the following new combinations: Pereirabolbus castaneus (Klug) and Pereirabolbus tucumanensis (Boucomont) .
