O. (A.) exaratus Mulsant 1844

Originally described from Central France [différentes parties du midi de France ”]. I have examined specimens from England, France, Morocco, Portugal, and Spain, including the male genitalia ( Fig. 3 ), to make certain that the specimens represent only one species, and to make certain that O. (A.) strangulatus Régimbart 1906 is a distinct species, not a junior synonym of O. (A.) exaratus Mulsant. Type specimens of O. (A.) exaratus Mulsant , including the male genitalia, should be examined to confirm my decisions. Type specimens will probably be in the Mulsant collection at the Paris Museum (MNHN).
