Technomyrmex hades

The type collection was obtained from a fogging sample.

Identification
Bolton (2007) - The yellow petiole of this arboreal species is very distinctive. It is the same colour as the middle and hind coxae and contrasts strongly with the dark mesosoma and gaster. T. hades is closely related to Technomyrmex pluto, another arboreal species from Sulawesi that has a yellow petiole, but pluto tends to be larger and has the propodeal dorsum and declivity yellow, has longer scapes (SI 120 - 121) and has yellow tibiae that are the same colour as the tarsi.

Distribution
North Sulawesi.

Distribution based on Regional Taxon Lists

Worker
Holotype. TL 2.6, HL 0.61, HW 0.56, SL 0.64, PW 0.39 WL 0.80. Indices: CI 92, SI 114, OI 27, EPI 73, DTI 138.

Frontal carina with 2 setae: in profile the posterior seta approximately at the level of the anterior margin of the eye. Dorsum of head posterior to this entirely lacks setae. With head in full-face view the anterior clypeal margin with an extremely shallow median concavity; sides of head shallowly convex and the posterior margin transverse, without a median indentation. Eyes located in front of midlength; outer margin of eye touches the outline of the side in full-face view. With mesosoma in profile the mesonotal outline is mostly more or less flat but curves posteriorly into a short oblique declivitous face. Number of setal fairs on mesosoma: pronotum 2; mesonotum 0; propodeal dorsum 0; lateral margins 0 propodeal declivity I, just above the spiracle. With the propodeum in profile its dorsum and declivity meet in a blunt angle. Straight-line length of propodeal dorsum in profile less than depth of declivity to spiracle. Gastral tergites 1 - 4 each with numerous setae, distributed everywhere on the sclerites; maximum length of setae on first gastral tergite is slightly less than the maximum diameter of the eye. Head, mesosoma and gaster dark brown to black; petiole yellow and strongly contrasting. Middle and hind coxae, trochanters and tarsi yellow; femora and tibiae Drown, the latter slightly paler than the former.

Paratypes. TL 2.4 - 2.6, HL 0.60 - 0.63, HW 0.54 - 0.58, SL 0.62 - 0.65, PW 0.38 – 0.40, WL 0.82 - 0.86 (2 measured). Indices: CI 90 - 92, SI 112 - 115, OI 26, EPI 69 -70, DTI 135 - 137. As holotype but pronotum with 2 - 3 pairs of setae; lateral margins of propodeal declivity with 1 - 2 pairs, but if 2 then one of the pairs is very short.
