Scape short, SL/CS 0.75 [0.70, 0.77], with short dorsal carina basally, strong parallel costulae extending scape. Promesonotal dorsum convex, metanotal groove shallow, but visible. Propodeal teeth long. Petiolar node cubic in profile, NOH/NOL 0.84 [0.78, 0.89], petiole relatively low, PEH/NOL 1.51 [1.43, 1.60]. General appearance coarsely rugose, ground surface microreticulate, dull. Head dorsum longitudinally rugose and microreticulate, occiput and sides rugoso-reticulate and microreticulate. Alitrunk dorsum rugoso-reticulate and coarsely microreticulate. Mesopleuron usually microreticulate. Dorsum of petiolar node rugoso-reticulate and microreticulate, dorsum of postpetiole longitudinally rugulose and microreticulate. Polygonal striation continuous on 1st gastral tergite, posteriorly disrupted. Basal part of first gastral tergite microreticulate (see fig. 7.), MRG 181.7 ±26.4 [150, 230].
