Worker
Holotype. TL 2.6, HL 0.75, HW 0.62, CI 83, ML 0.37, MI 49, SL 0.39, SI 63, PW 0.33, AL 0.70. Mandible with preapical dentition reduced to a mere denticle. Dorsolateral margin of head in full-face view with 3 freely laterally projecting fine stiff hairs: one just behind level of eye, one in apicoscrobal position, one just posterior to this; dorsal surface of dorsolateral margin of occipital lobe also has 1-2 shorter hairs that are directed more dorsally than laterally. Cephalic dorsum with a sparse transverse row of erect hairs along occipital margin and with at least one other pair anterior to this. Dorsum of head sharply and densely reticulate-punctate to reticulate-granulate, with only faint scattered vestiges of rugular sculpture. Occipital lobes large and in full-face view more strongly flared laterally than is usual in this group. Apical funicular segment distinctly constricted basally. Entire dorsal alitrunk and side of pronotum sharply densely punctate. Pleurae and side of propodeum densely evenly reticulate-punctate. Anterior coxae more or less smooth. Pronotal humeral hair long, filiform and straight to shallowly curved. Dorsal alitrunk with numerous erect stiff hairs, 3-4 pairs on pronotum and 4 pairs on mesonotum. First gastral tergite with numerous filiform shallowly curved hairs. Dorsal surface of hind femur without standing hairs; dorsal (outer) surfaces of hind tibia and basitarsus each with a few long erect freely projecting hairs. Petiole node in profile bluntly subconical, with a well defined steep anterior face. Basigastral costulae feebly developed and short, no longer than disc of postpetiole.

Paratype. TL 2.5, HL 0.73, HW 0.60, CI 82, ML 0.35, MI 48, SL 0.38, SI 63, P W 0.32, AL 0.72.
