Holotype: TL 5.2; HW 1.11; EL/HW 0.31; SI 103.

This small brown species has large eyes and a long scape which surpasses the occiput when laid back. The propodeum is rounded as in Messor syriacus. The psammophore is distinct but less developed compared with M. syriacus and the whole body is evenly brownish, not bicoloured as in M. syriacus. The postpetiole is long and low as in Messor crawleyi and Messor hismai but this species is distinctly different from both of these in the shape of the propodeum. There are long body hairs over the promesonotum and a few shorter hairs on the first gastral tergite.
