Description
Worker
Holotype. TL 1.4, HL 0.59, HW 0.55, CI 93, ML 0.12, MI 21, SL 0.26, SI 48, PW 0.32, AL 0.60. Characters of dexis-complex.

Punctures on vertex broad, scattered, distance separating one puncture from another is greater than the diameter of each puncture. Eye with 7 ommatidia in total. Pronotum distinctly broader than long in dorsal view, with scattered punctures on an otherwise smooth surface. Petiole node in dorsal view broader than long (discounting spongiform tissue). Disc of postpetiole smooth. Basigastral costulae fine and faint, but extending back over at least the basal third of the tergite.
