Worker
Bolton (2000) - TL 4.3-4.5, HL 1.01-1.05, HW 0.75-0.83, CI 74-79, ML 0.95-0.96, MI 91-94, SL 0.86-0.90, SI 108-115, PW 0.44-0.48, AL 0.98-1.08 (2 measured).

Characters of mandibularis-complex. Mandibles very long, the outer margins diverging anteriorly at full closure. Distal preapical tooth closer to apicodorsal tooth than to proximal preapical tooth. Eye small, protuberent, with 5 ommatidia in the longest row.a on middle and hind femora small, ovate, located close to dorsal apex; hind femora long (ca. 0.92-0.94). Propodeum in profile with a sharp triangular tooth dorsally and a small triangular lobe at base of declivity, the two linked by a narrow lamella. In dorsal view propodeal teeth at least as broad as in profile. Lateral spongiform lobe of petiole narrow, no more than an extension of the posterior collar down the side of the node. Disc of postpetiole reticulate-punctate. First gastral tergite smooth, the basigastral costulae vestigial, shorter than the posterior spongiform collar of the postpetiole.

Type Material
Bolton (2000) - Holotype worker, BRAZIL: Sao Paulo, V. Estr. Santos, Meio da Serra, 22.xii.1957, no. 2088 (W. W. Kempf) [examined].
