Scarabaeinae : Onthophagini

Onthophagus ( Figs. 35–36 ) is a large genus found throughout the world and consists of approximately 2,000 species (Tarasov and Kabakov 2010). The two species taken in this study ( Table 1) were found only in the dung traps, and neither was abundant, seeming instead to prefer more open habitats as in my other pitfall study in a secondary forest remnant on the grounds of INPA in Manaus (unpublished data).
