Head about 2.1X as wide as frontovertex, in profile about 1.7X as high as deep, tangent to frontovertex forming an angle of about 110° 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 105°; frontovertex not widening in front of anterior ocellus, with distinct, fairly coarse, polygonally reticulate sculpture of mesh size generally subequal to eye facet, but of larger mesh in front of anterior ocellus, 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 narrowly rounded; antenna as in Fig. 251; scape broadened and flattened, about 2.5X as long as broad; funicle with F1-F3 subequal, relatively small, subquadrate, F4-F6 larger, gradually increasing in size, F4 quadrate, F5-F6 longer than broad; clava about 4.4X as long as broad and about 1.5X as wide as F6, not curved downwards towards apex, slightly longer than funicle, sutures parallel, sensory area small, at apex only giving it a pointed or narrowly rounded appearance; eye slightly overreaching occipital margin, clothed with dense 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 63.5, HH 48, FV 30, POL 14.5, OOL 6, OCL 2, AOL 8.5, EL 32.5, EW 26, MS 18, SL 28, SW 11.

Thorax with pronotum hardly exposed behind head, its posterior margin broadly concave, not angular medially; pronotum with similar sculpture to that in ocellar area; mesoscutum with slightly shallower sculpture than in ocellar area, but of generally slightly larger mesh; 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 1.9X as broad as long; scutellum about 1.1X as broad as long, apex with a pair of slender, elongate setae; hind femur about 3.8X as long as broad; fore wing with venation and setation as in Figs 252, 253; propodeum medially about 0.05X as long as scutellum.

Paratype. Mandible with two acute teeth and a rounded upper tooth; palp formula 3-2; funicle with linear sensilla present only on F4-F6. Relative measurements: OL 53, GL 14 [MT 52].

Variation. Females vary in overall length from 0.85-1.00mm, the mid and hind coxae may be slightly paler than in the holotype, with the ventral surface of the hind coxa dusky white and the hind tarsus may be slightly dusky.

Male. Unknown.
