Worker
Holotype. TL 6.6, HL 1.20, HW 1.06, CI 88, SL 1.02, SI 96, AL 1.87. Characters of vigilans group and the following. Maximum diameter of eye 0.07. First gastral sternite with a mid-ventral longitudinal translucent carina that extends the length of the segment. First gastral tergite in profile with its anteroventral angle extended forward as a broadly triangular tooth, just above the helcium. In ventral view the extended anteroventral angles of the first tergite are seen to be drawn out as incurved triangular broad teeth or short stout horns on each side of the helcium. In dorsal view the anterior face of the first gastral tergite forms a broad concave arc that is extended forward and inward on each side by the broadly triangular curved angles. Propodeal declivity above the basal tooth with a narrow uneven lamella that terminates dorsally in a small tooth or tubercle. Sculpture everywhere on the glossy dorsum longitudinally costate-rugulose between broad foveolate punctures that are mostly sharply defined. On the second gastral tergite the longitudinal costate-rugose sculpture predominates.

Paratypes. TL 5.9–6.6, HL 1.11–1.16, HW 1.05–1.11, CI 95–96, SL 1.00–1.08, SI 94–97, AL 1.82–2.02 (3 measured).
