Description
Worker. Measurements: TL: 2.40–2.90; HL: 0.56–0.63; HW: 0.52–0.58; SL: 0.48–0.58; PW: 0.35–0.42; WL: 0.66–0.78. Indices: CI: 87–95; SI: 91–102; OI: 24–27; EPI: 70–88; DTI: 110–124 (n = 50, from Bolton 2007[9]).
Head. Anterior clypeal margin with a feeble, shallow median indentation; head in full-face view with a small shallow indentation medially and strongly convex sides; eyes of moderate size with approximately nine ommatidia in longest row (OI: 24–27), located in front of midlength, with outer margins just fail to break outlines of head sides. Mesosoma. In profile the mesonotal outline evenly curved; propodeal dorsum making a distinct obtuse angle with declivity in profile. Pilosity. Frontal carina with two pairs of setae; pronotum with 1–3 pairs; mesonotum bare or with one pair (usually none); propodeal dorsum bare; lateral margins of propodeal declivity with one or two pairs, usually with one pair above spiracle, another pair higher up; gastral tergites 1–4 each with abundant scattered long setae (length of setae relatively less than eye diameter or even subequal) on sclerites. Sculpture. Body sculpture finely and densely reticulate-punctate, general appearance dull. Colour. Head, mesosoma, petiole and gaster black-brown to black; tarsi of mid- and hind legs yellow.

Ecological and biological notes
Technomyrmexalbipes nests and forages in and beneath fallen wood and rocks, in tree trunks, in leaf litter, in twigs, on the forest floor, on low vegetation, and into the canopy (Bolton 2007[9]). The species is known to feed on honeydew of a broad range of sap sucking attended hemipterans including the mealybug vectors of pineapple wilt disease (Sulaiman 1997[11]).
Geographic range
A successful introduced species that has spread worldwide including the Australian, the Afrotropical, and the Malagasy regions (Bolton 2007[9]).
