Identification. This morphospecies can be distinguished from the other species and morphospecies of collected Onthophagus , in the case of males, by the head without a marked front clypeal suture and with a smooth surface with angular horns of variable size; small eyes; clypeus widened towards the anterior margin; pronotum strongly dotted with bristles protruding from points; and anterior medial region of pronotum weakly or strongly convex (pers. obs.). In females, head with a marked front clypeal suture forming a small transverse carina and horns as conical protuberances towards the base of the eyes, in some females these protuberances are poorly developed and form a transverse carina towards the posterior bor- der of the head; pronotum is strongly dotted with bristles emerging from each point; anterior medial region of the pronotum with two lateral projections (pers. obs.). Elytra interstriae are dotted with bristles at each point and are present in both males and females (pers. obs.).

Distribution. In the study area, this abundant morphospecies (770 individuals) was found between 700 m to 850 m a.s.l. with a preference for open areas of wooded pasture and open pasture (769 individuals).
