Nomenclature

 *  yemene. Tetramorium yemene Collingwood & Agosti, 1996: 335, fig. 13 (w.q.m.) YEMEN.

Worker
Holotype: TL 2.6; HL 0.67; HW 0.58; SL 0.43; EL/HW 0.232; CI 86.5.

This species, like T. jizani, resembles T. simillimum having distinct frontal carinae extending back almost to the occiput. The head and alitrunk have strong longitudinal striae with intermediate reticulate sculpture which is more weakly developed on the propodeum. The nodes have punctulate sculpture only. The head and alitrunk dorsum have short blunt hairs and there is one long oblique hair at each side of the head below the eye. The petiole has two pairs and the postpetiole three pairs of hairs. The head and alitrunk are brown and the gaster is dark, the legs and antennae yellowish.

Queen
TL 3.60, has similar colour, sculpture and pilosity to the worker but the gaster hairs are more numerous. The propodeal spines are well developed.

Male
TL 2.80, has a large expanded mesonotum, shining without sculpture except at the sides; the scutellum and propodeum are longitudinally striate. The head has moderately dense punctulate sculpture which becomes transverse on the occiput behind the eyes. There is one oblique hair at each side of the head below the eyes as in the female castes.
