Head ( Fig. 196) about 2.2X as wide as frontovertex, in profile about 1.5X as high as deep, tangent to frontovertex forming an angle of about 100° with that of face; occipital margin sharp, not carinate; no distinct oval depression adjacent to eye near occipital margin; ocelli forming an angle of about 95°; frontovertex not widening in front of anterior ocellus, with distinct, fairly coarse, polygonally reticulate sculpture of mesh size generally subequal to eye facet, not shallower above top of scrobes; temple and gena with much shallower, hardly elongate, fine polygonally reticulate sculpture; top of scrobes with shallow, regular, polygonally reticulate sculpture, scrobes smooth; interantennal prominence and mouth margin with slightly shallower, polygonally reticulate sculpture; scrobes shallow, indistinctly margined, broadly ∩-shaped; interantennal prominence dorsally rounded; antenna as in Fig. 195; scape broadened and flattened, nearly 3X as long as broad; funicle with F1-F5 subequal, relatively small, subquadrate, F6 larger and longer than broad; clava about 3X as long as broad and about 1.5X as wide as F6, not curved downwards towards apex, about as long as funicle, sutures parallel, sensory area small, at apex only giving it a pointed or narrowly rounded appearance; eye slightly overreaching occipital margin, clothed with fairly conspicuous setae, each about as long as diameter of facet; malar sulcus present, but very indistinct; clypeal margin clearly concave, virtually straight medially. Relative measurements: HW 48, HH 36.5, FV 21.5, POL 11.5, OOL 2.5, OCL 3, AOL 7, EL 27, EW 22, MS 16, SL 20, SW 7.

Thorax with pronotum hardly exposed behind head, its posterior margin broadly concave, not angular medially; pronotum and mesoscutum with similar sculpture to that in ocellar area; axilla with finer, shallower sculpture than mesoscutum; scutellum with 3 pairs of setae, dorsally with very fine, polygonally reticulate sculpture that is a little deeper than sculpture on mesoscutum, and of much smaller mesh, sculpture slightly longitudinally elongate towards side, extreme side and apex completely smooth and shiny; visible part of mesoscutum about 2X as broad as long; scutellum about 1.3X as broad as long, apex with a pair of slender, elongate setae; hind femur about 3.8X as long as broad; mid basitarsus with 6 or 7 ventral pegs; mid tibial spur about as long as basitarsus; fore wing with venation and setation as in Figs 197, 198; propodeum medially about 0.08X as long as scutellum. Relative measurements: FWL 51, FWW 22.5; HWL 33, HWW 8.
