| Technomyrmex bicolor|
Nothing is known about the biology of Technomyrmex bicolor.
Bolton (2007) - A member of the Technomyrmex bicolor group. The colour pattern of bicolor, with head and gaster uniformly very dark brown and the mesosoma, petiole and all the appendages a strongly contrasting yellow, is unique in the genus. Some species in the bicolor group have the head and mesosoma lighter than the gaster but no other has the above arrangement.

Bolton (2007) - TL 2.9, HL 0.62, HW 0.55, SL 0.70, PW 0.40, WL 0.82. Indices: CI 89, SI 127, OI 27, EPI 62, DTI 135.
Dorsum of head behind clypeus entirely lacks setae. Anterior clypeal margin with a semicircular median notch which is conspicuous and has sharply defined margins; inner margin of notch rounds into lateral portion of anterior c1ypeal margin. Posterior margin of head shallowly indented medially in full-face view and outer margins of eyes just fail to break the outline of the sides. Dorsum of mesosoma and declivity of propodeum without setae. Metathoracic spiracles very close to metanotal groove. In profile the length of the propodeal dorsum is slightly greater than the depth of the declivity to the spiracle. First gastral tergite without setae; second gastral tergite with 1 pair of setae (the sclerite is abraded, it is possible that 2 pairs were originally present); third gastral tergite with 2 - 3 pairs; tergite 4 is embedded in glue but 2 - 3 pairs of setae should probably be present. Strikingly bicoloured species: head capsule and gaster very dark brown, almost black; mandibles, antennae, mesosoma, petiole and all leg segments the same shade of clear yellow.
