Mandible with a spiniform preapical tooth that is separated from apicodorsal tooth by a distance at least equal to its length. A minute preapical denticle also present just proximal of mandibular midlength. Scape with an obtuse but pronounced subbasal bend; hairs on leading edge that curve toward base of scape are narrowly spoon-shaped and shorter than maximum width of scape. Apicoscrobal hair apparently absent (but this may have been lost). Ground-pilosity of cephalic dorsum and promesonotum spatulate to narrowly spoon-shaped and the former with a pair of short simple more erect hairs near the occipital margin. Pronotal humeral hair long and fine but mesonotum without standing hairs of any form. Pilosity of first gastral tergite consisting solely of sparse flagellate hairs that are very fine and uniformly slender. Propodeal declivity with a broad lamella that is angulate at top and bottom. With petiole in profile the ventral surface without spongiform tissue; lateral lobe of node large and conspicuously spongiform; height of anterior face of node greater than length of dorsum (excluding posterior collar). In dorsal view petiole node broader than long; disc of postpetiole glassy smooth. Basigastral costulae strong, longer than disc of postpetiole.
