Head with occiput moderately shiny metallic green; frontovertex largely with a moderate metallic, dark green sheen, occipital margin, eye margin and area in front of anterior ocellus somewhat coppery; temple, gena and scrobal area distinctly coppery-purple mixed with some violet; frontovertex, gena and interantennal prominence with relatively sparse, scattered, inconspicuous brown setae; radicle dark brown; scape dark brown with a slight brassy and purple sheen; pedicel dark brown, orange-brown at extreme apex; flagellum yellow; mandible dark amber-brown; maxillary palpus pale yellow; thorax generally dark brown to black; pronotum with a brassy and coppery sheen; mesoscutum with a relatively bright, metallic, blue-green sheen in anterior 0.75X, posterior 0.25X coppery; tegula brown with a slight brassy sheen; axilla and anterior 0.8X of scutellum with a coppery purple to coppery sheen, sides and apical 0.2X of scutellum with a distinct metallic brassy and dark green sheen; metanotum and mesopleuron dark purple-brown with a slight brassy sheen; setae on dorsum of thorax dark brown and fairly conspicuous; fore coxa pale yellow; fore femur pale yellow in proximal 0.3X, distally dark brown, fore tibia pale orange with a broad, brown, subbasal band to about 0.5X, tarsus pale orange; mid coxa brown proximally, pale yellow distally; mid femur pale yellow in proximal 0.75X, distally dark brown, tibia pale yellow with a dark brown subbasal band to about 0.4X, spur and tarsus pale orange; hind coxa pale yellow; hind femur pale yellow in proximal 0.4X, distally dark brown, tibia pale yellow at base and apex otherwise dark brown, tarsus pale yellow proximally, pale orange distally, apical tarsomere slightly dusky; wings virtually hyaline, but fore wing ( Fig. 443) very weakly infuscate; propodeum slightly shining, dark purple-brown, side metallic green and blue, a distinct group of silvery setae outside spiracle, these not extending down side towards hind coxa; gaster largely dark purple-brown, with some brassy, purple and green reflections, Gt1 dorsally bright metallic green and blue-green with posterior margin broadly coppery mixed with some brassy and purple; gonostylus dark brown.

Head in profile, about 1.4X as high as deep; occipital margin weakly carinate; ocelli forming an angle of about 55°; inner eye margins diverging very slightly in front of anterior ocellus; frontovertex with evenly spaced piliferous punctures along inner eye margins and none in front of anterior ocellus, punctures very shallow and about as wide as eye facet; ocellar area with moderately deep, fairly regular, polygonally reticulate sculpture of slightly smaller mesh than eye facet, sculpture in front of anterior ocellus a little shallower but mostly of slightly larger mesh, but still smaller than facet; temple and gena with irregular, longitudinally elongate, polygonally reticulate sculpture of similar depth to that in ocellar area; scrobes with polygonally reticulate sculpture; interantennal prominence virtually reaching frontovertex, with shallow, regular, polygonally reticulate sculpture; antenna as in Fig. 446; scape about 1.5X as long as broad, dorsal margin clearly convexly curved; F1 clearly longer than broad and F6 quadrate, linear sensilla present only on F4-F6; clava slightly broadened, about 1.3X as wide as F6, about as long as F3-F6 combined, outer suture slightly oblique, sensory area extending about 0.3X along venter of clava. Relative measurements: HW 65, HH 63, FV 16, POL 7.5, OOL 0.5, OCL 6.5, AOL 10, EL 48, EW 36.5, MS 24, SL 30, SW 19.5.

Thorax with slightly transversely elongate, polygonally reticulate sculpture on pronotum that is generally of similar mesh size, and about as deep as that on frontovertex; mesoscutum with polygonally reticulate to imbricate-reticulate sculpture that is about as deep as that on frontovertex, but generally of slightly larger mesh size; axilla and anterior part of scutellum with similar sculpture to that on mesoscutum, apical one-third of scutellum with shallower sculpture; visible part of mesoscutum about 1.5X as broad as long; scutellum about as long as broad with apex acute and slightly overhanging the propodeum medially; setae on mesoscutum moderately dense, separated by a little less than their own lengths and of more or less uniform length, those on scutellum similar, subapical setae clearly longer; hind femur about 3X as long as broad; fore wing with venation and setation as in Figs 443, 445; propodeum medially about 0.16X as long as scutellum, with some regular, moderately deep, polygonally reticulate sculpture in middle 0.3X or so, lateral areas with shallower, irregular sculpture. Relative measurements: FWL 101.5, FWW 36.5; HWL 74, HWW 16.5.

Gaster with syntergum about 0.8X as long as mid tibia, with apex narrowly rounded; ovipositor ( Fig. 444) slightly exserted, the exserted part about 0.8X as long as mid tibial spur or about 0.2X as long as mid tibia. Relative measurements: OL 102.5, GL 44.5 [MT 73].
