Description

Worker

Holotype. TL 2.2, HL 0.60, HW 0.48, CI 80, ML 0.23, MI 38, SL 0.29, SI 60, PW 0.29, AL 0.59. Characters of emdeni-complex; closely related to emdeni and answering that description except for the following. Cephalic dorsum densely clothed with pale spoon-shaped to scale-like ground-pilosity but this pilosity not reproduced on promesonotal dorsum where the ground-pilosity is of inconspicuous scattered small hairs. There are a few spoon-shaped hairs on the dorsolateral margins, especially on the posterior half of the pronotum, but the overall appearance of the ground-pilosity is much less dense and much weaker than on the cephalic dorsum. Side of alitrunk entirely reticulate-punctate, without smooth areas anywhere. Disc of postpetiole unsculptured.

Paratypes. TL 2.1-2.2, HL 0.60-0.64, HW 0.48-0.50, CI 78-82, ML 0.22-0.23, MI 35-38, SL 0.28-0.30, SI 57-60, PW 0.29, AL 0.58-0.59 (4 measured).
