Worker
Holotype. TL 3.2, HL 0. 87, HW 0.68, CI 78, ML 0.31, MI 36, SL 0.44, SI 65, PW 0.42, AL 0.92. Mandible relatively short for a member of this group; preapical tooth broken on each mandible in holotype. Dorsolateral margin of head in full-face view with 6 or more freely laterally projecting filiform hairs, including one in apicoscrobal position; dorsal surface of dorsolateral margin, from level of eye to occipital corner, also with standing hairs that are directed dorsally or more dorsally than laterally. Cephalic dorsum with standing fine hairs present from occipital margin to a level anterior to highest point of vertex. Dorsum of head finely and narrowly reticulate-rugulose, the rugulae and their small reticulae finely densely punctulate. Apical funicular segment not constricted basally. Entire dorsal alitrunk and side of pronotum sharply and very densely punctate to punctate-granulate, promesonotum also with very small rugulae. Pleurae and side of propodeum everywhere densely punctate to reticulate-punctate. Anterior coxae punctate and with vestiges of transverse costulate sculpture. Pronotal humeral hair long and filiform, shallowly curved. Dorsal alitrunk with numerous erect simple hairs, more than 4 pairs on pronotum and 6 or more pairs on mesonotum. First gastral tergite with numerous filiform shallowly curved hairs. Dorsal and ventral surfaces of hind femur with a row of suberect hairs, sparser ventrally than dorsally; dorsal (outer) surfaces of hind tibia and basitarsus each with a few long erect freely projecting hairs. Propodeal teeth stout, in profile longer than basal width. Petiole in profile subclavate, the node forming an even shallow curvature that in dorsal view is longer than broad.
