Description

Worker

Holotype. TL 6.3, HL 1.20, HW 1.15, CI 96, SL 1.10, SI 96, AL 2.10. Paratypes. TL 6.0–6.6, HL 1.16–1.23, HW 1.06–1.20, CI 91–98, SL 0.99–1.19, SI 95–103, AL 1.91–2.14 (10 measured). Maximum diameter of eye 0.15–0.20. Characters of vigilans group and the following. Maximum diameter of relatively large eye 0.19. First gastral sternite with a median longitudinal carina at least on the posterior half of the sclerite. First sternite at each side of the anteroventral median process forms a short projecting angle or low prominence. First gastral tergite in dorsal view with bluntly angular anterolateral corners; sides slightly constricted behind the corners. Propodeal declivity with a blunt tooth near base and another, smaller, tooth near apex; the basal teeth appear very broad and coarse in dorsal view. Petiole in dorsal view bluntly subtriangular, widest posteriorly. All dorsal surfaces of head and body with coarse broad foveolate punctures, separated by longitudinal costae or elevated narrow flat surfaces. The entirety, including bases of foveolae and surfaces that separate them, is completely covered with extremely fine dense microsculpture and is dull and opaque. This microsculpture also occurs on at least the upper half of the propodeal declivity and is present, though less intensely, on the scapes and legs.
