Identification

Bolton (2007) - A member of the Technomyrmex grandis group. Close to Technomyrmex grandis but much less luxuriantly hairy. T. grandis is larger than wheeleri, has more posteriorly located eyes and a longer and more broadly rounded propodeum. The setae of wheeleri are much sparser and shorter than those of grandis: outstanding setae on the scapes and tibiae are shorter than the width of the segment from which they arise in wheeleri, longer in grandis; the longest setae on the first gastral tergite are always much longer than the maximum diameter of the eye in grandis, usually shorter than the maximum diameter of the eye in wheeleri.

Description

Worker

Bolton (2007) - TL 3.3 - 3.6, HL 0.70 - 0.79, HW 0.62 - 0.72, SL 0.86 – 0.98, PW 0.45 – 0.51, WL 1.06 - 1.12 (10 measured). Indices: CI 89 - 95, SI 129 - 140, OI 27 - 32 EPI 80 - 86, DTI 137 - 155.

Dorsum of head in profile with 4 - 6 pairs of setae in front of level of posterior margin of eye; usually with some much shorter setae among the longer pairs. The longest setal pair is located about half way between level of posterior margin of eye and posterior margin of the head and is followed by several shorter pairs before the posterior margin is reached. Ventral surface of head with a few short setae present. With head in full-face view the posterior margin and sides with outstanding short setae, those on the sides inclined anteriorly; anterior clypeal margin with a weak to moderate median impression; posterior margin of head impressed. Eyes located just in front ofmidlength of head (EP 80 - 86), their outer margins usually just fail to break the outline of the sides of the head but in some individuals just break the outline. Scapes with sparse, short setae on all surfaces, the longest at most equal to the width of the scape but usually slightly shorter. Pronotum with several pairs of short setae; mesonotum usually with a single short pair, located close to the metathoracic spiracle; rarely a more anterior pair may also be developed. Propodeum in profile with a short dorsum that rounds into the declivity. Propodeal dorsum without setae but some elevated pubescence may be present; declivity with 2 - 3 pairs of setae. Gastral tergites 1 – 4 each with setae; longest setae are usually shorter than the maximum diameter of the eye but may be subequal in some individuals. Middle and hind tibiae with short projecting setae, the longest distinctly shorter than the maximum tibial width. Colour medium brown to black.
