This work updates species and county distribution of Scarabaeinae dung beetles in Oklahoma. Historical collections and literature records, as well as data from a private regional collection, were compiled to document species in the state. The study adds eight new dung beetles for the state, bringing the total to 39 species. In addition, 78 new county records were reported. Two behavioral groups, tunnelers and rollers are present, but dwellers in the subfamily Scarabeinae have not been documented in Oklahoma. By updating the species list and known distribution, more research can be focused on dung beetles that provide numerous ecological services and benefit livestock producers.
