Identification. This species can be distinguished from other Onthophagus species by the prolonged clypeus on its anterior margin in the form of a “ T ”, slightly bidentate in the females; males with slightly angled horns, variable in size towards the base of the eyes; females with two conical protuberances towards the base of the eyes; and pronotum with a pair of small tubercles towards the midline that do not extend beyond the anterior border ( Zunino and Halffter 1997).

Distribution. It is distributed throughout almost the entire country in Colombia, according to collection records. However, some differences between these species were observed. In the study area the species were found in all habitats between 650–1200 m a.s.l., and were very abundant (1954 individuals). However, a preference was observed for areas with forested vegetation (riparian forest relics and high secondary forest) where 1695 individuals were collected with some specimens reported for open areas such as wooded grasslands (259 individuals) and only seven individuals in the open grassland.
