Diversity and distribution of the dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) of Colombia

Based on field collections, national museums, and the literature, a total of 249 species in 32 genera and six tribes of coprophagous beetles (Scarabaeinae) were identified for Colombia. Some 27 from the total of the genera are endemic to the Neotropical region and two are cosmopolites; 77.7% of the total of the species are registered locally. A good number of the species, specially of the genera Canthon, Canthidium, Uroxys, and Ateuchus, are deposited in national collections. Many of the specimens are still unidentified and contain new species. The major richness is presented in the Guyana and Norandina biogeographic provinces with 76 and 68 species, respectively. The major number of species was found in intermediate rainfall sites between 2,500 and 3,500 mm annually. Factors such as elevation and mosaic soils have a strong influence over the diversity patterns of these beetles. A more detailed study in the different regions and habitats is required to learn more about the distribution and biogeographic affinities of this group in Colombia.
