Description
Worker
Bolton (2000) - TL 2.0-2.1, HL 0.52-0.54, HW 0.35-0.36, CI 66-69, ML 0.09-0.11, MI 18-22, SL 0.28-0.30, SI 80-86, PW 0.25-0.26, AL 0.48-0.53 (3 measured).
Mandible with a basal series of 5 narrow acutely triangular teeth distal of which are two smaller but similarly shaped teeth; basal tooth immediately follows basal lamella, without a long secondary lamella on the masticatory margin and without alternation of high acute and low rounded teeth. Eye large, with 6-7 ommatidia in the longest row. Apicoscrobal hair simple, almost straight, slightly thickened apically. Pronotum without a median longitudinal carina. Dorsal alitrunk and side of pronotum evenly densely reticulate-punctate. Propodeal spines long and extremely thin, needle-like, the propodeal lamella reduced to a minute carina on the declivity below each spine.
Type Material
Bolton (2000) - Syntype workers, ARGENTINA: Salta (F. Silvestri) Museo Civico di Storia Naturale, Genoa (not seen).
