Belongs within: Dolichoderinae.

Technomyrmex is a genus of smaller, mostly arboreal ants found in warmer regions of the Old World.

Characters (from Bingham 1903): Worker with head more or less cordate, occiput emarginate, generally broader than anterior margin of head; mandibles broad, triangular, masticatory margin equal in length to outer margin, the former armed with numerous small teeth; clypeus broad, convex in the middle, extending angularly up between antennal carinae; frontal area indistinct; antennal carinae short, wide apart, parallel; scape moderately long, flagellum thickening slightly towards apex; eyes comparatively large, placed in front of transverse middle line of head. Thorax moderately broad, viewed in profile deeply emarginate at meso-metanotal suture; pro-mesonotal suture distinct but not incised; mesonotum convex, raised slightly above pronotum, the two together forming a convex gibbosity; metanotum convex, basal portion slightly sloping forward, apical portion much longer and sloping backwards; legs comparatively short and stout, calcaria pectinate, claws simple. Pedicel without a proper elevated node, simply with an oval flat thickening in the middle; abdomen at base very much produced, raised and gibbous, overhanging pedicel, posteriorly conical, with an apical cloacal aperture. Queen closely resembling worker except head proportionately broader posteriorly; ocelli present and distinct though small; thorax more massive; mesonotum and scutellum nearly flat, very slightly convex; slight constriction present behind wings; fore wing with a radial and one cubital cell; metanotum broad, sloping obliquely back to apex, only slightly convex, nearly flat; pedicel very short, together with abdomen as in worker.
