Onthophagus gibber and Onthophagus gibberosus ( d’Orbigny, 1905) ( Fig. 1 D, I; E, L)

The examination of the external morphology of the primary types of O. gibber d’Orbigny, 1905 (described from Cape Colony: Grahamstown) and O. gibberosus d’Orbigny, 1905 (described from Liberia) led us to consider both species names to be new synonyms under O. striatulus striatulus (Palisot de Beauvois, 1809) ( Howden & Cartwright, 1963) ( ICZN, 1999: Art. 23), a North American species widely distributed across the eastern part of USA, except Florida, Atlantic Coast of South Carolina and Georgia where occurs the subspecies O. striatulus floridanus Blatchley, 1928 ( Howden & Cartwright, 1963) . Therefore, the following new synonymies are established:
