Identification. This species can be distinguished from other Deltochilum by the head with a dorsal carina, with sharp and divergent clypeal teeth; well-marked deep cephalic scoring over the entire surface; the ninth interstria of the pseudo eplipleuron with a keel that exceeds half of the elytra and is not visible dorsally in the posterior part of the interstria; presence of subcircular dimpled interstriae and bright and raised irregular areas ( González et al. 2009).

Distribution. It is known in Colombia from the departments of Amazonas, Bolívar Caquetá, Cundinamarca, Guaviare, Meta, Nariño and Putumayo. There are records between 60–1200 m a.s.l. in mainland or gallery forests ( González et al. 2009). In riparian and high secondary forests between 850–950 m a.s.l. within the study area, nine specimens in riparian forest and 15 specimens were captured in high secondary forest, and only one individual was collected in wooded pasture.
