(Figs 356-365; Hab. E 57, G 58)  
 DIAGNOSIS. Female (length about 0.8-1.2mm): head black; clava yellow or pale orange; legs pale orange; fore wing generally weakly infuscate; hind wing generally weakly infuscate; ocelli forming an angle of about 75°; antenna with linear sensilla on F3-F6; fore wing (Fig. 361) about 2.7X as long as broad, postmarginal vein very nearly as long as stigmal vein (Fig. 357); mesoscutum and scutellum (Fig. 356) with uniform polygonally reticulate sculpture composed of rounded cells; scutellum with three pairs of subapical pits or pores that are mainly of subequal diameter to cell of reticulate sculpture; mid tibial spur about 0.9X as long as basitarsus. Male (length 0.95mm): almost identical to female, differing only in genitalia structure.   
Female (holotype): length, 1.04mm (CPD).  
Head generally black with a weak brassy sheen; antenna, including radicle, mainly pale orange, but F4-F6 brown, apical segments of clava slightly paler orange; mandible amber; palpi white; frontovertex and gena with relatively sparse, scattered, inconspicuous brown setae, interantennal prominence with relatively dense brown setae; thorax generally orange with a weak brassy sheen, neck of pronotum dark brown, mesopleuron pale orange, setae on dorsum of thorax relatively dense, brown and conspicuous; legs pale orange; fore wing (Fig. 361) generally weakly infuscate, more strongly so below marginal vein, venation slightly dusky pale orange; hind wing generally very weakly infuscate; propodeum orange, side slightly dusky; gaster pale orange, Gt1- Gt6 slightly dusky; gonostylus pale orange.  
Head (Fig. 359) about 3.9X as wide as frontovertex, in profile about 1.4X as high as deep; occipital margin not sharp; ocelli forming an angle of about 75°; with 7 or 8 scattered punctures below anterior ocellus and with relatively shallow, polygonally reticulate sculpture of much smaller mesh size than diameter of eye facet; antenna as in Fig. 358; scape about 2.4X as long as broad; F1-F2 subquadrate, very slightly longer than broad, F3-F6 transverse, segments slightly broader distad; clava slightly broadened, about as long as F3-F6 combined, 3-segmented, sutures hardly oblique, subparallel, sensory area slightly enlarged, at apex only giving the clava a weakly truncate appearance; malar sulcus present, distinct.. Relative measurements: HW 58.5, HH 50, FV 15, POL 5, OOL 1, OCL 4, AOL 5.5, EL 36, EW 34, MS 17.5, SL 24, SW 10.  
Thorax (Fig. 356) with polygonally reticulate sculpture on pronotum, mesoscutum, axilla and scutellum that is of similar depth to that on frontovertex but generally composed of uniformly, rounded, polygonal cells; visible part of mesoscutum about 1.6X as broad as long; scutellum about 1.1X as broad as long; scutellum with three pairs of subapical pits or pores that are mainly of subequal diameter to cell of reticulate sculpture; setae on dorsum moderately dense and of more or less uniform length, separated by less than their own lengths, apical setae on scutellum slightly longer; fore wing with venation and setation as in Figs 357, 361. Relative measurements: FWL 61, FWW 22.5; HWL 42, HWW 8.5.  
Gaster with hypopygium reaching about 0.8X towards apex; syntergum about 0.7X as long as mid tibia, with apex narrowly truncate; ovipositor hidden.  
Paratype. Funicle with linear sensilla present only on F3-F6. Relative measurements: OL 67, GL 20 [MT 99].  
Variation. Females vary in overall length from 0.76-1.15mm, the apical segments of clava may be yellow, the head varies from 3.7-4.1X as wide as the frontovertex, the ocellar angle varies from 50-75°, otherwise little variation in material available.  
Male: length 0.95mm.  
Almost identical to female, differing only in genitalia structure. Head as in Fig. 364; mesosoma as in Fig. 360); fore wing as in Fig. 365; antenna (Fig. 363) with clava 3-segmented, but with outer suture incomplete; phallobase (Fig. 362) slightly less than 3X as long as broad; digitus about 2X as long as broad with a single apical hook, paramere not developed, without apical seta; cuspis seta present; aedeagus about 4.5X as long as broad, about one-third as long as mid tibia, hardly longer than mid tibial spur. Relative measurements: HW 55, FV 15, SL 20, SW 9; AL 17.5, MT 51.5, MTS 16.5.
