Eye with 5-6 rows of ommatidia, and with 6-7 ommatidia in the longest row; EL 0.13-0.14 (EL/HW 0.28-0.30). MfL 0.45-0.52 (MfL/HW 0.98-1.00). Dorsal outline of propodeum in profile, from approximate site of metanotal groove to dorsal base of spine, evenly curved or at most with a very low, obtuse angle anteriorly. Propodeal spines in profile usually distinctly downcurved along their length. Degree of curvature of the spines is variable: in most it is striking but in a few it is not as pronounced, and in the very smallest workers it may not be apparent. Diameter of annulus of propodeal spiracle is about equal to the thickness of the propodeal spine at its midlength. Petiole node in profile small, more or less erect with respect to the peduncle, the node not obviously inclined posteriorly; narrowly but bluntly rounded dorsally, and with the anterior and posterior faces converging toward the dorsum. Sculpture of petiole node faint to vestigial laterally, absent from posterior surface. Height of petiole node in posterior view (from midpoint of the dorsal margin of the foramen to the apex) 0.86-0.95 x its maximum width. In dorsal view postpetiole 1.20-1.38 x broader than long; maximum width of postpetiole 0.93-1.15 x the length of a propodeal spine; maximum width of postpetiole 0.82-0.92 x the distance between the
