Onthophagus gazellinus View in CoL species group.

This group is diagnosed by the male having no head horns ( Figs. 5.7–8 View FIG View FIG View FIG View FIG ); male protibial apex with a tuft of long setae resembling a fine-pointed paintbrush ( Figs. 1.57 View FIG –58); pronotum with four transversely aligned tubercles along a straight carina ( Figs. 5.7–8 View FIG View FIG View FIG View FIG ), base unrimmed; metafemur light brown with fine punctures ( Figs. 2.57 View FIG –58); at the excavated posterior pronotal margin a line of 5–6 large, ocellate punctures with one short, stiff, upward pointing seta, punctures disappearing towards middle of the pronotal margin; apex of elytra and pygidium with long, erect setae.

Boucomont (1932) initially established this species group as his “10 e Groupe” and was supported by Kohlmann & Solís (2001) under the name of O. gazellinus species group. This group contains, at present, only two species, O. gazellinus Bates and O. onthochromus Arrow ( Table 7 View TABLE 7 ). Boucomont (1932) defined the group as having large species with long erect setae at the end of the elytra and on the pygidium; male head unarmed and female with two carinae; thorax base not rimmed; coloration light, elytral points brown. This species group is distributed from Nicaragua to Brazil.
