Description

Worker

Holotype. TL 4.4, HL 0.96, HW 0.83, CI 86, SL 0.90, SI 108, PW 0.60, AL 1.24. Maximum diameter of eye 0.21 (0.25 x HW) and with 10-11 ommatidia in the longest row. Mandibles finely longitudinally rugulose. Entire cephalic dorsum with only vestigial sculpture, a very feeble superficial reticulation visible. Median portion of clypeus conspicuously biconvex, without longitudinal carinae. Eyes with abundant anteriorly curved short hairs arising between the facets. Dorsal alitrunk virtually smooth except for the propodeum, which shows weak reticulation. Dorsal outline of propodeum rounded immediately behind the metanotal groove. Sides of pronotum shining, almost unsculptured. Mesopleuron densely sculptured, reticulate-punctate with some fine longitudinal rugulae. Sides of propodeum and metapleuron with sculpture intermediate in density between pronotum and mesopleuron. First gastral tergite with fine superficial shagreening between hairpits, almost smooth. Pilosity dense on all dorsal surfaces, the hairs erect to suberect everywhere. Scapes and tibiae with numerous suberect to subdecumbent short hairs. Colour light yellowish brown.

Paratype. TL 4.2-4.6, HL 0.92-0.98, HW 0.78-0.84, CI 85-88, S 0.86-0.92, SI 108-111, PW 0.59-0.62, AL 1.22-1.34. Maximum diameter of eye 0.20-0.22 (0.25-0.27 X HW) (4 measured). As holotype.

Type Material

Holotype worker, INDIA: Meghalaya, Khasi Hills, Shillong, 1O.v.1975 (R. Mathew) (The Natural History Museum).
