{Dorylus oraniensis major worker} The specimen shown in the photomontage is a major, from Southern Tunisia, Tozeur, collector T. Lackner, 16-17.iii.2003; and appears to match the (Emery 1915g) description of D. (D.) fulvus variety oraniensis, from Tunisia. The lower photograph is of three morphs from the Tunisia collection. The longitudinal groove on the propodeum, mentioned by Lucas as a differentiating feature, is clearly visible. Compared with the fulvus type redescription (W C Crawley for Santschi, 1928d) the metanotal groove is noticeably impressed rather than being "slightly indicated"; also the head does not narrow significantly at the occiput.
