Identification

Bolton (2007) - A member of the Technomyrmex bicolor group. This species is very similar to Technomyrmex impressus. It is possible that further collections may obviate the differences between them that are shown by the admittedly sparse samples currently available.

Description

Worker

Holotype. TL 4.1, HL 0.91, HW 0.80, SL 1.10, PW 0.54, WL 1.34. Indices: CI 88, SI 138, OI 28, EPI 79, DTI 163.

Paratypes. TL 4.0 - 4.1, HL 0.92 - 0.94, HW 0.80 - 0.81, SL 1.10, PW 0.55 - 0.57, WL 1.34 - 1.37 (2 measured). Indices: CI 86 - 87, SI 136 -138, OI 28 - 29, EPI 75 -79, DTI 160 - 164. As holotype.

Matching the description of Technomyrmex impressus but differing in colour and sculpture. Head, mesosoma and petiole light brown, the gaster very slightly darker than the mesosoma. (In impress us all are dark brown to black.)

Middle and hind coxae yellow, somewhat lighter than the mesosoma but not strongly contrasting. (In impressus the middle and hind coxae contrast very strongly with the mesosoma.)

Middle and hind tarsi dull yellow, approximately the same colour as the tibiae. (In impress us the middle and hind tarsi are much lighter than the tibiae and contrast strongly.)

Mesopleuron mostly smooth, at most with faint patches of superficial reticulation. (Mesopleuron entirely reticulate-punctulate in impressus.)

Dorsal surfaces of head and pronotum superficially sculptured. (In impressus the head and pronotum are densely reticulate-punctulate.)

Shagreenate sculpture of first gastral tergite weak and superficial. (Shagreenate sculpture of first gastral tergite is coarse and Intense in impressus.)

Type Material

Holotype worker (top specimen of 3 on pin), Malaysia: Sarawak, 4th Division, Gn. Mulu N.P., 1310 m., v-viii.l978, B.M. 1978-49 (P.M Hammond & JE. Marshall) (The Natural History Museum). Paratypes. 2 workers (middle and bottom specimens on same pin), with same data (BMNH).
