Tetramorium simillimum WORKER (drawn specimen) - TL 2.02, HL 0.51, HW 0.48, SL 0.40, PW 0.31 (TL 2.0-2.7, in Bolton, 1980: 319, illustrated side of head, alitrunk and pedicel profile; in my guide as Tetramorium species F)
Colour yellow-brown, gaster dark and shiny. Head, alitrunk and pedicel finely punctate with the puncturations generally arranged longitudinally. Erect hairs stout and moderately abundant. Propodeal spines short, triangular and upturned. Petiole node short, with the anterior and posterior faces near vertical; dorsum flat in profile but sloping downwards to the posterior. Small acute subpetiolar spine.

Widely distributed by commerce (Wheeler, 1922). Collingwood & Bolton (1975) report it as a tramp species of African origin, which can be found in hot-houses in Britain, and Bolton (1980) listed findings from all over Africa, plus mentioning the wide global distribution.

Egypt records - listed in Emery (1909c: 697); Forel (1907a) Ismailia, coll. Biró.
