A revision of the Onthophagus pexatus species-group, with description of a new brachypterous species (Coleoptera: Scarabaeidae: Scarabaeinae)
Abstract
The Onthophagus pexatus species-group is revised, with the known species—O. longipes Paulian, 1937; O. nammuldi Matthews, 1972; O. pexatus Harold, 1869; O. squalidus Lea, 1923—redescribed and a new species: O. bulga sp. nov., described. This species-group is centred in New South Wales, where both O. bulga and O. nammuldi are endemic. Onthophagus bulga is only the second flightless species of this large genus known from Australia.
