Explanation of Names
From Greek dicho "in two, split" plus tomi "cut" (1).
Checklist of the Scarabaeoidea of the Nearctic Realm (2) lists two North American species in genus: carolinus and colonicus. D. carolinus occurs throughout the eastern United States and Canada, D. colonicus from the southwest, Mexico south.
Dichotomius was mistakenly omitted in, but they did include the old genus Pinotus with two species; Pinotus spadiceus Luederwaldt 1928 and P. texanus Felsche 1901 whose status is unclear.
