Worker
Holotype: HL 0.91; HW 0.76; SL 0.82; EL 0.25; CI 83.8; SI 107.

The head of this species is more rectangular than in the other members of this group. The petiole is a high cone in profile 0.28-0.29 mm and narrow in dorsal view, 0.21 mm. The head and ali trunk are less sculptured than in Monomorium areniphilum but the main difference is the high, relatively narrow petiole.

Queen
The queen has a high, sharply angled petiole which, unlike in the other species, is almost smooth with very faint sculpture and the dorsum is emarginate. The M. areniphilum queen also has a high node but it is much more sculptured with a smoothly rounded crest.

Type Material
Holotype: queen, Oman, Qarn al-Alam, 31.V.1989, M.D. Gallagher.-Paratypes: 1 worker, 1 queen, same series as holotype.
