F. Genier et Hf. Howden, Two new central American Onthophagus latreille of the mirabilis species group (Coleoptera : Scarabaeidae, Scarabaeinae), COLEOPTS B, 53(2), 1999, pp. 130-144
Onthophagus barretti, new species, from Darien Province (Panama) and O. bre
viconus, new species, from Guatemala and Honduras are described and illustr
ated. Onthophagus orphnoides Bates is now considered a valid species and re
moved from synonymy with O. mirabilis Bates. The limits of the mirabilis sp
ecies group are redefined to exclude O. quetzalis Howden and Gill. A key is
given to the species in the mirabilis group.
