Identification. This species can be distinguished from other Dichotomius species by the clypeus and gena with transverse roughness; the front edge of the head is triangular and margined; transverse carina at the base of the eyes; smooth pronotum and in some specimens with some punctation. In males there are small triangular tubercles towards the posterior angles of the pronotum and in females the tubercles are absent ( Sarmiento-Garcés and Amat-García 2014).

Distribution. This species is distributed in the departments of Cundinamarca and Meta; between 200–1200 m a.s.l. ( Medina et al. 2001), restricted to 200 m in the Colombian Orinoco region ( Medina and Pulido 2009), although in the study area it was found between 700–1100 m a.s.l. It is a rare species represented in the sample by 17 individuals (scarce in museums and rare in field collec- tions) but which were found representing all the habitats available with forest cover for the study: high secondary forest (nine individuals), riparian forest (three individuals) and wooded grassland (five individuals).
