A new Panamanian species of scarab beetle of the subfamily Scarabaeinae, Onthophagus cambrai sp. nov., is described and illustrated. The character states of this species do not allow it to be placed in a known species-group of the New World. A revised key to the 26 species known from Panama is presented.
