Worker
Holotype. TL 3.0, HL 0.74, HW 0.49, CI 66, ML 0.10, MI 14, SL 0.39, SI 80, PW 0.32, AL 0.80. Characters of hoplites-complex. Dorsum of head with sparse short erect simple hairs behind highest point of vertex. Dorsolateral margin of head in full-face view without laterally projecting hairs; one or two short hairs project posteriorly from the occipital margin. Antennal scrobe smooth and shining, its posterior margin merely demarcated by a shallow impression of the surface, without a rim or edge marking the boundary of the scrobe. Eye with 7 ommatidia in the longest row. Short erect simple hairs present dorsally as follows: 2 pairs anteriorly on pronotum, one pair on mesonotum, 2 pairs on petiole node, 2 pairs on disc of postpetiole, 1 0 or more on first gastral tergite. Similar hairs also project forward in a spaced row down the anterior face of the front coxa, and sparse similar but suberect to subdecumbent hairs occur dorsally on the basal half to two-thirds of each femur. Pronotum transversely convex; posterior half of mesonotum and entire propodeum laterally marginate in dorsal view. Propodeal teeth elongate, narrow and acute apically; at least half the length of each tooth is free of the lamella. Anterior face of petiole node confluent with the elongate convex dorsum. Lateral spongiform lobes of petiole vestigial and almost invisible in profile; in dorsal view seen to be confined to a tiny outgrowth on each side at the posterolateral angles. Ventral spongiform curtain of petiole in profile scarcely deeper than the maximum depth of petiole itself. Ventral lobe of postpetiole slightly smaller than the exposed cuticular area of the disc. Whole body smooth and shining. Petiole laterally with feeble punctulate sculpture and both waist segments may have a few weak costulae laterally.

Paratypes. TL 3.0-3.1, HL 0.74-0.76, HW 0.48-0.50, CI 65-66, ML 0.11, MI 14-15, SL 0.40, SI 80-83, PW 0.30-0.33, AL 0.78-0.84 (2 measured). As holotype but both with pronotal hairs lost by abrasion so that only a single anterior hair remains in each.
