<paragraph pageId="77" pageNumber="78" type="mainText">Eye with 7-8 rows of ommatidia, and with 9-10 ommatidia in the longest row; EL 0.18-0.23 (EL/HW 0.30-0.34). Eye in profile not tear-drop shaped, not coming to a point anteriorly; the anterior and posterior curvatures of the eye almost equally convex. MfL 0.60-0.76 (MfL/HW 1.03-1.15). Oblique costulae on mesopleuron sparse and weak. In profile, the dorsal outline of the propodeum forms an even slope from just behind the metanotal groove to the base of the spine. Propodeal declivity lacks transverse costulae. Diameter of annulus of propodeal spiracle is slightly less than, to about equal to, the thickness of the short propodeal spine at its midlength. Petiole node in posterior view low and broad, its posterior surface usually with some reticulate-punctulate sculpture, at least on the lower half. Height of petiole node in posterior view (from midpoint of the dorsal margin of the foramen to the apex) 0.75-0.90 x its maximum width. In dorsal view postpetiole 1.33-1.42 x broader than long; maximum width of postpetiole 1.95-2.25 x the length of a propodeal spine; maximum width of postpetiole 1.25-1.50 x the distance between the apices of the propodeal spines. Disc of postpetiole entirely sculptured with reticulate-punctulation, and also usually with some weak rugulae present. Full adult colour uniform yellow.</paragraph>

As in the worker the postpetiole is very broad and entirely sculptured dorsally, and the propodeal spines are short.</paragraph>

Propodeal dorsum finely punctulate and with scattered fine, longitudinal rugulae. Propodeal dorsum without a median longitudinal carina, but upper half of declivity with a median carina present; a fine rugula on each side separates the declivity from the side of the propodeum. Propodeum in profile unarmed, the rounded angle between dorsum and declivity surmounted by a an extremely low, rounded cuticular crest. Postpetiole in dorsal view broader than long, the surface finely punctulate-shagreenate. Postpetiole in profile longer than high. Colour yellow.</paragraph>
