The Oryctini (Coleoptera: Scarabaeidae) are dynastine scarab beetles with a worldwide distribution consisting of 26 genera and about 230 species, of which 14 genera and 135 species are distributed in the Neotropical region. The species of this tribe occur in habitats ranging from temperate and tropical dry forests to rain forests and cloud forests from sea level to 2600 m in elevation. Some species feed on organic matter or decaying fruits while others bore into the stems of living plants, in which case they occasionally reach pest status. Knowledge of the tribe in the Neotropics is still fragmentary, necessitating further studies that address taxonomy, phylogeny, and geographical distribution patterns of the species. This study surveyed the Oryctini of Colombia. In Colombia there are 7 genera and 32 species, found in 29 departments, 330 municipal districts and approximately 628 specific localities. Heterogomphus curvicornis Prell, Megaceras jason (Fabricius), and Podischnus oberthueri Sternberg are reported for the first time from Colombia. Taxonomic descriptions and distribution maps are provided for all species. An identification key, in Spanish and English, is provided for all oryctine species that occur in Colombia. A checklist of the oryctine beetles of the Colombia is provided.
