( figure 60)

Diagnosis. Head with occiput sharply margined; post-occipital carina absent. Antenna with pedicel yellow; clava 1.9 or 3 times as long as broad, obtuse. Axillae sculptured. Scutellum with longitudinal median carina, with several transverse carinae originating from median carina to grooves. Dorsellum yellow, but dark on posterior margin. Propodeal median carina with attached short carinae. Petiole not apparent. Hind legs completely yellow.

Description. Head mostly yellow with occiput and area around ocelli black; occipital carina present, developed into translucent lamina; post-occipital carina absent. Antennal scrobe concolorous with other parts of face, yellow. Scape and pedicel yellow. Flagellum concolorous. Funicular segments all longer than broad, with F4 samely separated from F3 and clava, and distinctly four-segmented, with segments not becoming shorter and broadened towards clava simultaneously; F1 1.7–4 times as long as broad. Clava medially same breadth as funicle, obtuse, 1.9 or 3 times as long as broad.

Dark parts on mesosoma black. Pronotum with yellow parts occurring more than on posterior end, never translucent. Pronotum dark medially or completely on anterior half, yellow on posterior half, rounded into neck, without distinct transverse carina anteriorly. Mid lobe of mesoscutum yellow with broad, black patch on anterior two-thirds medially, with engraved reticulations, covered with setae all over the dorsum, without longitudinal median carina. Axillae mostly dark, yellow laterally, reticulate, bare. Axillula completely yellow. Scutellum completely yellow, with longitudinal median carina, from which carina, several transverse carinae originated from and reached broad sublateral grooves, which grooves united at middle point posteriorly. The area lateral to the sublateral grooves smooth. Dorsellum smooth, yellow, but dark on posterior margin, without toothlike structure directing posteriorly. Propodeum completely smooth, with median carina, mostly yellow, with dark patch along median carina. Propodeal median carina with short carinae attached, at least translucent along margins, thus appearing yellow, anteriorly raised into a cup-shape but not too much as a translucent, elongate and tongue-shaped protuberance. Petiole not apparent.

Hind legs completely yellow. One hind tibial spur more than 1.5 times length of the first tarsomere. Hind tarsi with the first segment at least as long as the second.
