(Figs 417-422; Hab. E 68)  
 DIAGNOSIS. Female (length about 1.3-1.8mm): fore wing (Fig. 419) completely hyaline; head with 4 or 5 setae medially in front of anterior ocellus; area immediately below eye completely smooth and shiny; antenna (Fig. 417) with scape about 4.0X as long as broad; funicle with all segments slightly longer than broad; clava with sensory area extending about 0.3X as long ventral surface; fore wing (Fig. 419) with linea calva open near posterior wing margin; costal cell with two lines of setae on ventral surface in apical half; syntergum about 1.3X as long as mid tibia; ovipositor about 2X as long as mid tibia; gonostylus about 2.5X as long as mid tibial spur. Male: unknown.   
Female (holotype): length, including ovipositor, 1.76mm; excluding ovipositor, 1.61mm (CPD).  
Head mainly black; frontovertex generally with a weak brassy and coppery purple sheen with some blue reflections; scrobes with a weak dark green sheen mixed coppery purple, interantennal prominence with a weak coppery purple sheen; temple and gena with a weak dark metallic green sheen, position of malar sulcus broadly marked metallic coppery purple; frontovertex, gena and interantennal prominence with short, moderately conspicuous, dark brown setae; clava brown; pronotum black with a coppery purple and brassy sheen; propleuron and prosternum dark brown; mesoscutum black with a slight metallic dark blue and purple sheen; tegula dark brown with a slight purple and brassy sheen; axilla dark brown with a purple sheen; scutellum largely metallic dark green, purplish anteriorly between axillae, extreme apex shining metallic green, side largely coppery mixed metallic green; dorsum of thorax clothed with dark brown setae; metanotum dark orange-brown with a weak brassy sheen; mesopleuron dark purple-brown with a weak brassy sheen; mesosternum dark brown; fore femur proximally white, very pale orange distally, tibia and tarsus very pale orange; mid femur mostly white, apex pale orange, tibia largely white, but very pale orange at apices, spur very pale orange, tarsus pale orange; hind femur white, apical one-third pale orange, tibia white proximally, apex very pale orange, tarsus very pale orange; fore wing (Fig. 419) hyaline; propodeum dark orange-brown with a weak purple and brassy sheen, setae anterior to and outside spiracle white, translucent and moderately conspicuous; gaster dark brown dorsally mainly with a coppery and purple sheen, but mixed brassy and blue, side and venter mainly with a mixed green, blue, brassy, purple and coppery sheen; gonostylus dark brown with apex widely pale orange.  
Head about 8.3X as wide as frontovertex, with 4 or 5 setae medially in front of anterior ocellus, a line of sparse setae along inner eye margin continued along lower eye margin; ocelli forming an angle of about 35°; temple and gena slightly more shiny than frontovertex, with slightly shallower, longitudinally elongate, strigose to striate-reticulate sculpture, area immediately below eye completely smooth and very shiny; eye separated from scrobal margin by less than 0.5X diameter of ocellus, area between eye and scrobe with shallow, transversely elongate, imbricate-reticulate sculpture; sculpture on interantennal prominence polygonally reticulate but a little shallower that on frontovertex; antenna as in Fig. 417; scape hardly broadened, about 4.1X as long as broad; funicle with all segments only slightly longer than broad, becoming wider distad; clava slightly broadened, about 1.2X as wide as F6, nearly as long as F2-F6 combined, outer suture slightly oblique, sensory area enlarged, extending ventrally about 0.3X length of clava, apex conspicuously obliquely truncate. Relative measurements: HW 70.5, HH 69, FV 8.5, POL 4, OOL 0, OCL 8.5, AOL 10, EL 52, EW 44, MS 28, SL 37, SW 9.  
Thorax (Fig. 420) with visible part of mesoscutum about 1.9X as broad as long; scutellum about as long as broad; fore wing with venation and distribution of setae as in Figs 418, 419; mid tibial spur shorter than basitarsus; propodeum (Fig. 420) medially about 0.16X as long as scutellum, with some shallow, irregular sculpture medially; about 7 or 8 setae anterior to and outside spiracle. Relative measurements: FWL 72, FWW 29; HWL 52, HWW 12.  
Gaster with hypopygium reaching about 0.5X towards apex (but slightly retracted towards anterior); syntergum about 1.3X as long as mid tibia, with apex very acute; ovipositor slightly exserted, the exserted part about as long as mid tibial spur or 0.25X as long as mid tibia.  
Paratype. Funicle with linear sensilla present only on F4-F6; hypopygium Fig, 421; ovipositor Fig. 422. Relative measurements: OL 72, GS 24 [MT 35].  
Variation. Females vary in length from 1.29-1.81mm, some funicle segments may be quadrate, the purple area in the position of the malar sulcus may be absent, and there may be only 4 setae outside the propodeal spiracle.
