 DIAGNOSIS. Female (overall length about 0.9-1.0mm): scape mostly dark brown; pedicel mostly brown; flagellum pale orange, clava dusky pale orange; fore coxa white, mid and hind coxae brown. sometimes partly dusky white; fore and mid femora white with a broad, brown subapical band; fore and mid tibia white with a brown subbasal band; hind femur white with a brown subapical band; hind tibia mostly dark brown; gaster dark brown, Gt1 medially and basal sternites medially pale yellow; frontovertex about half head width; antenna (Fig. 251) with scape about 2.5X as long as broad, funicle with F1 narrower than pedicel, F1-F3 subequal, small, F4-F6 larger, F5-F6 longer than broad; linear sensilla only on F5-F6; clava slightly longer than funicle and nearly 4.5X as long as broad; palp formula 3-2; scutellum with 3 pairs of setae and polygonally reticulate to longitudinally elongate striate-reticulate sculpture, deeper than that on mesoscutum; mid basitarsus with 7 or 8 ventral pegs; mid tibial spur about as long as basitarsus; fore wing with stigmal vein (Fig. 253) about as long as postmarginal vein, but shorter than marginal vein; hypopygium reaching about 0.8X towards apex of gaster; ovipositor nearly 4X as long as gonostylus and slightly exserted, the exserted part shorter than mid tibial spur. Male: unknown.   
 Female ( holotype ): length, including ovipositor, 1.00mm; excluding ovipositor, 0.94mm (CPD).   
Head dark brown to black with a metallic sheen; occiput with a weak coppery sheen; frontovertex generally with a coppery sheen, mixed metallic dark green near anterior ocellus; scrobal area, temple and gena with a moderate coppery purple sheen; frontovertex, gena and interantennal prominence with a few scattered, inconspicuous, brown setae; maxillary palpus white; radicle dark brown; scape dark brown in proximal 0.7X, apex white; pedicel brown with apex pale orange; flagellum very pale orange-yellow, clava slightly dusky, pale orange; thorax dark brown to black with a weak metallic lustre; pronotum with a slight coppery sheen; mesoscutum with blue, blue-green, dark green and brassy reflections mixed with some coppery, posterior margin narrowly coppery purple; tegula dark purple-brown with a weak brassy sheen; axilla dark purple-brown with a coppery purple sheen; scutellum dorsally virtually matt with a very weak coppery purple sheen, apex and side slightly silky in appearance with a weak coppery purple and brassy sheen; mesopleuron with a moderate purple sheen; fore coxa white; fore femur white in proximal 0.5X, a broad, dark brown, subapical band, extreme apex pale yellow, tibia white basally, a broad, dark brown subbasal band, apical 0.5X pale orange, tarsus pale orange; mid coxa dark brown, apex very pale yellow; mid femur white in proximal 0.5X, a broad, dark brown, subapical band, extreme apex white, tibia white at extreme base, a narrow, dark brown subbasal band, apical 0.6X very pale yellow to very pale orange, spur very pale orange, tarsus pale orange; hind coxa dark brown; hind femur with proximal 0.3X white, a broad, dark brown, subapical band, extreme apex white, tibia with extreme base white, extreme apex very pale orange, otherwise virtually completely dark brown, tarsus pale orange; wings hyaline, but fore wing with a small, weakly infuscate area below marginal vein (Fig. 253); propodeum dark brown with a weak purple sheen; gaster dark brown with coppery purple, green and blue reflections, Gt1 medially pale yellow, basal sternites medially white; gonostylus brown.  
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. Relative measurements: FWL 76, FWW 34; HWL 49, HWW 12.5.  
Gaster with hypopygium reaching about 0.8X to apex to apex; last tergite about 0.6X as long as mid tibia, with apex rounded; ovipositor slightly exserted, the exserted part about 0.6X as long as mid tibial spur or about 0.2X as long as mid tibia.  
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.
