Description

Worker

Holotype. TL 2.7, HL 0.75, HW 0.60, CI 80, ML 0.26, MI 35, SL 0.34, SI 57, PW 0.34, AL 0.77. Characters of emdeni-complex; closely related to emdeni and answering that description except for the following. Inner margin of mandible with a very slender cuticular crest; carina-like. Outer curvature of eyes just visible in full-face view, the upper scrobe margins straight rather than shallowly convex. Cephalic dorsum densely clothed with spoon-shaped to scale-like ground-pilosity but this pilosity not reproduced on promesonotal dorsum. Promesonotal ground-pilosity consists of scattered small spatulate hairs, the overall appearance of which is much less dense and much weaker than on the cephalic dorsum. Pronotal humeral hair absent; mesonotum with a single pair of short standing hairs. First gastral tergite with numerous erect stiff hairs that are slightly thickened or flattened apically, or weakly remiform. Dorsum of head and alitrunk reticulate-punctate but side of alitrunk with katepisternum, most of metapleuron and part of side of propodeum smooth. Disc of postpetiole smooth and shining.
