saharensis (Dorylus (Typhlopone) fulvus var. saharensis nov. var., Santschi, 1926e: 231, illustrated, worker & male) from "Sahara" = Algeria, Laghouat, 8.viii.1919, Surcouf - see below.

{Dorylus saharensis type worker} The photomontage is of the type major worker of saharensis collated from

{Dorylus crosi type worker} The photomontage is of the type worker of crosi collated from

This is very similar to the media 1 worker from Tunisia (below).

{Dorylus saharensis type minor} The photomontage is of the type minor worker of saharensis collated from

This is identical to the minima 1 worker from Senegal (below).

{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.
