Identification. This species can be distinguished from other Dichotomius species by the head with transverse clypeal carina with or without lateral teeth and trituberculate vertex carina; pronotum with central protuberances in the form of almost square tubercles from which two small projections of the same size are projected on each (Sarmiento-Garcés and Amat-García 2014). Distribution. In Colombia it is distributed in the departments of Guaviare, Meta and Vichada (Medina and Pulido 2009; Sarmiento-Garcés and Amat-García 2014). In the study area, it was recorded at 750 m a.s.l., higher than the one reported by Medina and Pulido (2009) and Sarmiento-Garcés and Amat-García (2014). Nine individuals were recorded, categorizing it as a rare species, in wooded pastures, secondary high forest and riparian forest cover.
