Nothing is known about the biology of Technomyrmex textor.
Identification
Bolton (2007) - A member of the Technomyrmex textor group. Together with Technomyrmex gilvus and Technomyrmex dubius, Technomyrmex textor forms a complex. of closely related small monomorphic yellow species that share the same predominant absence of setae on the head capsule, mesosoma and gaster, and share a characteristic mesonotal shape in profile. They all also have a very weak and shallow median clypeal impression, indented posterior margin of the head and relatively anteriorly located eyes.
Of the three the New Guinea species gilvus has the longest scapes (SI 120 - 126) and has eyes that are located more posteriorly (EPI 60 - 65) than in the other two, where the combined ranges are SI 91 - 100 and EPI 44 - 54. T. dubius has eyes that are smaller (OI 23 - 25) than in textor (OI 27 - 30) and are distinctly more inset from the outer margins of the head in full-face view.

Description
Worker
Bolton (2007) - TL 2.5 - 2.9, HL 0.52 - 0.64, HW 0.45 - 0.58, SL 0.45 - 0.54, PW 0.32 – 0.40, WL 0.68 - 0.86 (l0 measured). Indices: CI 87 - 92, SI 93 - 100, OI 27 - 30, EPI 44 - 52, DTI 130 - 140.
Dorsum of head behind clypeus entirely lacks setae. Anterior c1ypeal margin with a shallow inconspicuous median impression. Posterior margin of head in full-face view with a median indentation. Eyes of moderate size and located far forward on the head (EPI < 60), well in front of the midlength; in full· face view their outer margins just touch, or just fail to touch, the outline of the sides. Dorsal surfaces of mesosoma and declivity of propodeum entirely lack setae. In profile the mesonotal dorsal outline with a horizontally flat, or nearly flat, anterior section and a shorter, much more steeply sloped declivitous surface posteriorly, the two separated by a distinct angle or step in the outline. Propodeal dorsum convex. in profile and meeting the declivity through a blunt angle or narrow curve; straight-line length of dorsum distinctly less than depth of declivity to the spiracle. Gastral tergites 1 - 3 without setae, gastral tergite 4 with 1 - 2 pairs of setae present. Head, mesosoma, petiole and legs yellow. Gaster the same colour or slightly darker, a light yellowish brown.
