Diagnosis

Recognised by the labrum with 4 – 6 digits, scape and legs yellow, facial sculpture reticulate, vertex rugulose, mesosoma coarsely rugose-areolate and bluish green with reddish dorsal patches, and fore wing pilose but with the basal area and speculum bare and the speculum open basally, and the hind wing with reduced setation, both in size and numbers, in the basal half. Of the specimens where it could be observed, the variation in labral digits ranged in females from 4 (4 specimens), 5 (3) to 6 (3), and in males from 4 (13), 5 (8) to 6 (8).

Female. Length 3.02 – 3.8 mm.

Colour: Head and mesosoma blue green. Scape yellow; pedicel and anellus yellowishbrown; flagellum dark brown to black. Mandible yellowish-brown with margins and teeth dark brown; maxilla and labium dark brown. Coxae dark blue; legs beyond coxa yellow but fore leg pale brown subbasally. Fore wing hyaline; venation pale brown. Petiole same as mesosoma; gaster dark brown.

Head in frontal view subtriangular; head width 1.1 – 1.2× height; face finely reticulate; scrobal depression shallow, laterally rounded, weakly rugulose; eyes bare, inter-ocular distance 1.4 – 1.7× eye height; malar space 0.6 – 0.7× eye height; malar depression absent; supraclypeal area about as long as broad, shorter than clypeus, smooth; clypeus weakly sculptured, nearly smooth with scattered setae; epistomal sulcus vaguely defined; anterior tentorial pit strongly impressed; anteclypeus absent, clypeal margin slightly protruding and broadly rounded medially. Labrum with 4 – 6 digits. Mandibular formula 3:2. Palpal formula 3:3. Occiput aciculate, shallowly emarginate in dorsal view, dorsal margin abrupt; temples broad. Scape not reaching median ocellus. Pedicel subconical, as broad as F1. Flagellum with 8 funiculars; flagellum length 1.2 – 1.3× head height; anellus disc-shaped; F2 same width as pedicel, 1.6 – 2.0× as long as broad, 1.1 – 1.3× as long as F3; following funiculars subequal in length, equal in width; clava subconical.

Mesosoma length 1.1 – 1.2× height. Mesoscutal midlobe scabrous, bare; lateral lobe coarsely rugose-areolate; notauli deep. Axilla rugose-reticulate, dorsally rounded, on roughly same plane as scutellum; scutoscutellar sulcus broad, regularly foveate, narrowly separated from transscutal articulation medially; scutellar disc slightly longer than broad, coarsely rugose-areolate; frenal line coarsely areolate; frenum rugose-areolate; axillular sulcus absent; axillula rugose-areolate. Propodeal disc broadly rounded, without depression or carina, coarsely rugose-areolate; callus areolate-reticulate, bare; callar nib absent. Prepectus triangular dorsally, weakly narrowed ventrally, sculpture rugose-areolate. Mesepisternum rugose-areolate laterally, smooth ventrally, straight anterior to mid coxa. Upper mesepimeron smooth to weakly rugose ventrally; lower mesepimeron rugulose; transepimeral sulcus distinct. Metepisternum laterally rugulose. Propleuron convex, coriaceous. Postpectal carina prominent. Hind coxa 1.4 – 2.5× as long as broad, weakly reticulate; hind femur 5 – 6× as long as broad, with even cover of short, dense setae; hind tibia densely setose. Fore wing 2.3 – 2.6× as long as broad, 2.2 – 2.7× as long as mesothorax; basal cell and speculum bare, costal cell and wing disc densely setose; marginal fringe relatively long; submarginal vein with several long setae in basal half, with smaller setae apically; marginal vein with minute setae; stigmal vein 1.5 – 3.3 x as long as broad, perpendicular to anterior wing margin; uncus absent; stigmal sensilla indistinct; postmarginal vein 1.4 – 2.2× as long as stigmal vein. Hind wing has reduced setation, both in size and numbers, in the basal quarter; costal cell setose apically.

Metasoma: Petiole cylindrical, linear in profile, 1.8 – 2.7× as long as broad, 1 – 1.6× as long as hind coxa, rugose, anterior carina strong, lateral margin rounded, ventral sulcus absent. Antecostal sulcus irregularly sculptured; acrosternite posteriorly rounded; apical setae of hypopygium with several long hairs on each side of midline. Ovipositor slightly curved cephalad; subapical carina present; first (ventral) valvula with 10 – 11 small, closely spaced teeth, second (dorsal) valvula with 8 – 10 annuli that are broadly separated dorsally, carinae weakly coalescing; third valvula separate.

Male. Length 3.17 – 3.31 mm. Head width 1.1 – 1.2× height; scape yellow; flagellum with 8 funiculars, clava 1 or 2-segmented, flagellum length 1.6 – 1.7× head height, anellus disc-shaped, F2 broader than pedicel, 1.7 – 2.5× as long as broad; legs beyond coxa yellow. Petiole 6.6 – 7.0× as long as broad, 2 – 2.3× as long as hind coxa.
