Technomyrmex subgracilis Bolton, 2007 |
The only non-type specimen was collected in rainforest litter.
Identification
Bolton (2007) - A member of the T. pallipes complex in the Technomyrmex albipes group. Identified by its combination of the distribution of setae on the dorsal head, lack of indentation in the anterior c1ypeal margin, relatively large eyes that are at the midlength of the head, long scapes and angular propodeum.

Description
Worker
Holotype. TL 3.9, HL 0.82, HW 0.71, SL 0.84, PW 0.51, WL 1.18. Indices: CI 87, SI 1I8, 01 30, EPI 98, DTI 137.
Frontal carina with 2 setae: in profile the posterior of these at the level of the anterior margin of the eye. Dorsum of head behind this with 1 pair of setae at the level of the posterior margin of the eye and behind this is a final pair, located well in front of the posterior margin. Posteriormost setae the longest, about equal to the maximum diameter of the eye. With head in full-face view the anterior clypeal margin without a median indentation. Sides of head feebly convex and converging anteriorly; corners of posterior margin of head very broadly rounded and in full-face view the posterior margin convex on each side of a small median indentation. Eyes located at mid length of head and their outer margins just fail to touch the outline of the sides of the head: With mesosoma in profile the mesonotal outline is a shallowly convex slope with a short, feeble declivity posteriorly. Number of setal pairs on mesosoma: pronotum with 2; mesonotum with 1, short and located posteriorly, at the point where slope of mesonotum changes; propodeal dorsum 0; lateral margin of propodeal declivity 1. Propodeum in profile with the dorsum flat and slightly longer than the depth of the declivity to the spiracle; propodeal dorsum and declivity meet in an angle. Gastral tergites 1 - 4 each with numerous setae, distributed everywhere on the sclerites; maximum length of setae on first gastral tergite slightly greater than the maximum diameter of the eye. Head, mesosoma, petiole and gaster black. Coxae, femora and tibiae of middle and hind legs black. Basitarsi of hind legs infuscated basally, only slightly lighter than the tibia, becoming lighter towards the apex where they are the same dull yellowish brown colour as the remaining tarsal segments.
