( Figures 4–6 )

Diagnosis

Female holotype. Length 1.67 mm. Body generally dark brown, with metallic silver reflection; scape yellow, pedicel slightly dusky yellow, flagellum and club brown; legs yellow, only hind femur dark brown; fore wing hyaline.

Head about 1.1× as wide as high; and about 1.8× as wide as frontovertex; occipital margin sharp; eye about 1.2× as long as malar space; scape about 1.7× as long as club which is longer than F5–F6 combined, and about 3.4× as long as wide, other proportions of antenna as in Figure 5 ; palp formula 4-3; mandible with one tooth and a truncation; ocelli forming obtuse angle; OCL about 0.5× diameter of ocellus; distance between torulus and anterior ocellus about 3.3× length of torulus; first segment of maxillary palp as long as first segment of labial palp. Relative measurements: HW 40, FV 21, FVW 13, TT 5, TM 2, POL 11, AOL 6, EL 20, MS 18,

Mesoscutum with well-developed cell structure; sculpture on scutellum with relatively larger mesh than that of mesoscutum; fore wing ( Figure 6 ) about 2× as long as wide; apex of fore wing with a well-developed marginal fringe; hind wing about 4× as long as wide; mid basitarsus segment equal to segments II–IV combined together.

Hypopygium well developed, about 2.8× as wide as long, but not reaching apex of gaster; ovipositor slightly exserted, the exserted part about 0.1× as long as gaster.

Female paratype (slide mounted). Outer plates of ovipositor ( Figure 4 ) 4.9× as long as wide; OL about 4.8× GL; ovipositor 1.68–1.77× as long as mid tibia. Relative measurements: OL 79 , GL 19 , OPL 54 , OPW 11 , MT 47 , MTS 13 .

Variation. The length varies from 1.5 to 1.8 mm, otherwise little variation in material examined.

Male. Length 1.25–1.38 mm. Generally similar in colour to female, but legs dusky yellow with hind femur and tibia dark brown. Antennae with F1 about 2× as long as pedicel and almost 3× as long as wide; F4–F6 each about 2× as long as wide; setae on funicle about half as wide as segments; clava solid.
