Worker
Holotype. TL 3.7, HL0.87, HW 0.87, CI 100, SL 1.08, SI 124, PW 0.56, AL 1.25, ED 0.26. Paratype. TL 3.6, HL 0.88, HW 0.88, CI 100, SL 1.06, SI 120, PW 0.54, AL 1.21, EL 0.25.

Head as long as broad, sides convex, posterior margin almost straight, posterior corners rounded. Anterior clypeal margin produced in the middle and straight, with a longitudinal carina. Mandible with 6 teeth, the 3rd reduced, the 5th as large as the 4th and the basal tooth. Eyes ovate, convex, moderately large, placed slightly behind the mid length of head. Antennal scapes extending about 2/5 of their length beyond posterior margin of head. Frontal carina short, reaching to anterior margin of eyes. Mesosoma slender, strongly medially constricted; metanotal groove conspicuous; in lateral view pronotum and mesonotum together form a convexity; propodeum with dorsal face straight, elevated backward, declivous face truncate and slightly concave, posterodorsal corner angulate. Petiolar node high, subtriangular, anterior face slightly convex, posterior face straight. Gaster about 1.5 times longer than head.

Mandibles longitudinally striate, clypeus coarsely longitudinally rugose; head, mesosoma and petiole finely and densely striate and punctate, dull; striations on constriction of mesosoma coarser; sides of propodeum densely reticulate. Gaster smooth and shining. Setae soft and long, abundant on head and on gaster, anterior portion of pronotum and mesonotum with short setae. Colored chestnut, gaster black.
