Description

Worker

Holotype. TL 3.5, HL 0.84, HW 0.72, SL 0.87, PW 0.52, WL 1.22. Indices: CI 86, SI 121, OI 28, EPI 94, DTI 152.

Answering the description of Technomyrmex andrei except for colour, as follows. Head, mesosoma and petiole dull orange, gaster brown with extensive yellowish areas on the tergites. Gastral sternites 1 - 5 the same colour as the petiole. Front coxa same colour as mesosoma, trochanter yellow; femur and tibia as coxa or slightly lighter. Middle and hind coxae and trochanters pale yellow, femora and tibiae light brownish yellow; tarsi pale yellow. Setae on gastral segments 2 - 4 are mostly lost by abrasion or are adherent to the surface, but the setal pits are clearly visible.

Paratypes. (2, of which only smallest is measured as head of larger paratype is severely. crushed). TL 3.1, HL 0.76, HW 0.67, SL 0.84, PW 0.49, WL 1.10. Indices: CI 88, SI 125, OI 25, EPI 94, DTI 145.

First paratype (head crushed) as holotype but gaster darker and the paler dorsal areas less conspicuous. Setae are distinct on gastral tergites 2 - 4. Second paratype smaller than holotype. Head, mesosoma, petiole and legs yellow, the middle and hind coxae slightly lighter. Gaster brown with pale areas dorsally as in holotype.

Type Material
