Worker
Holotype. TL 2.5, HL 0.68, HW 0.53, CI 78, ML 0.23, MI 34, SL 0.31, SI 58, PW 0.29, AL 0.68. Characters of emdeni-complex. Inner margin of mandible with a narrow translucent cuticular crest. Outer curvature of eyes just visible in full-face view, upper scrobe margins approximately straight. With head in profile the scrobe strongly developed behind the level of the eye, deep, clearly defined and with sharp dorsal, ventral and posterior margins. Cephalic dorsum densely clothed with very conspicuous spoon-shaped to scale-like ground-pilosity but this pilosity not reproduced on promesonotal dorsum where it consists of scattered small spatulate hairs, the overall appearance of the ground-pilosity is much less dense and much weaker than on the cephalic dorsum. One or two very short erect hairs present on occipital margin at each side, near apices of occipital lobes. Pronotal dorsum without standing hairs but humerus with a short straight hair that is directed laterally. Mesonotum with 3 pairs of short erect hairs, the posterior pair the longest. First gastral tergite with numerous erect stiff hairs, some of them slightly thickened or flattened apically, or weakly remiform. Dorsum of head and alitrunk uniformly reticulate-punctate. Side of alitrunk with katepisternum smooth, and a smooth patch present that covers the upper metapleuron and lower side of the propodeum. Disc of postpetiole smooth and shining.

Paratypes. TL 2.4-2.6, HL 0.70-0.71, HW 0.56-0.58, CI 80-82, ML 0.24, MI 33-34, SL 0.32-0.33, SI 57, PW 0.31-0.32, AL 0.68 (2 measured).
