Worker
Holotype. TL 2.0, HL 0.56, HW 0.38, CI 68, ML 0.26, MI 46, SL 0.36, SI 95, PW 0.22, AL 0.55. Characters of the mayri-complex. Preapical tooth spiniform, slightly longer than maximum width of mandible. Cephalic dorsum with 4-6 erect hairs along the occipital margin, the pair nearest the midline curved or narrowly looped apically; a simple pair present at level of highest point of vertex. Preocular notch strongly present; ventral surface of head with a broad shallow preocular transverse impression posterior to the broad and deeply incised postbuccal groove. Pronotal humeral hair flagellate, pronotum otherwise without erect hairs; mesonotum with one pair of erect flagellate hairs. Dorsal alitrunk reticulate-punctate but individual punctures shallower and more spaced out on pronotum. Dorsal surfaces of waist segments and first gastral tergite with flagellate hairs, those on the first gastral tergite erect and very long, sparse, restricted to a pair near the base and another pair near the apical margin. Katepisternum and most of metapleuron smooth, side of propodeum partially weakly punctulate. Propodeum armed with a pair of short straight spines, elevated at about 45°, not markedly upcurved, the length of one of which is equal to or slightly greater than distance separating their bases. Dorsal (outer) surface of hind basitarsus with 1-2 long erect flagellate hairs. Petiole in profile with anterior face of node slightly shorter than length of dorsum, in dorsal view petiole node as long as broad. Disc of postpetiole smooth, unsculptured except for a few extremely feeble short costulae at its anterior margin. In dorsal view basigastral costulae shorter than disc of postpetiole.
