Xanthopimpla hienae sp. nov.

( Figs 2g, 4f, 6d, 8e, 10b, 12f, 14d, 16c)

Diagnosis. Hind slope of vertex with two small oblique brown marks, nearly forming a V-shape medially; scutellum moderately convex; propodeum with area superomedia 0.6x as long as wide; metasomal tergites with median black bands (except tergite 2 with two black spots); ovipositor straight, ovipositor sheath 0.25x length of hind tibia.

Description (Holotype female). Body length 9.0 mm, fore wing 7.5 mm, ovipositor sheath 0.5 mm. Head. First antennal flagellomere 1.6x length of second; diameter of lateral ocellus 1.15x ocellar-ocular distance; frons polished; face quadrate, with numerous, minute punctures; clypeus 0.6x as high as wide, apical margin thin and emarginate; malar space about 0.3x basal width of mandible.

Mesosoma . Epomia short; mesoscutum with moderately dense hairs, notaulus present on anterior 0.3 of mesoscutum, extending to anterior level of tegula; scutellum convex, lateral carina forming lateral flange, medially 0.3x as high as first flagellomere width, gradually narrowed to apex; mesopleuron subpolished, with sparse minute punctures on upper half and dense punctures on lower part, epicnemial carina present on lower 0.6, postpectal carina medially forming wide and moderately high flange; metapleuron polished; propodeum with strong carinae, area superomedia 0.6x as long as wide; propodeal spiracle elongate, 4.0x as long as wide. Hind leg with femur 2.2x as long as wide, 0.9x length of tibia, hind basitarsus 0.3x length of tarsus, 2.0x second tarsomere, third tarsomere 1.5x as long as wide; mid tibia with one bristle near apex, three bristles at apex; hind tibia with one bristle near apex, two bristles at apex; largest bristles on mid and hind tarsal claws widened. Fore wing with vein 2 rs-m equal to vein 3 rs-m; cu-a opposite Rs+M; hind wing with first abscissa of vein Cu 1 about 0.4x length of vein cu-a.

Metasoma. First tergite as long as apical width; dorsolateral carina weakly present behind spiracle, median longitudinal carina extending to oblique groove; tergite 3 onwards densely, finely punctate; ovipositor straight; ovipositor sheath 0.25x length of hind tibia, lower valve with several small apical ridges.

Colour. Lemon yellow; antenna dark brown, except outer side of scape, pedicel and some first flagellomeres yellowish; ocellar area black; hind slope of vertex with two small oblique brown, forming nearly V-shape medially; mesoscutum with three transverse continuous black spots medially and black spot in front of scutellum; tegula dark and transparent posteriorly; propodeum with black band at base, slightly broad laterally to second lateral area; basal 0.2 of mid tibia and mid tarsus dark brown; hind leg with 0.7 under and lateral side of trochanter black, posterior face of femur with large black spot; anterior face with small brown spot along upper margin, basal 0.2 of tibia and tarsus black; wings hyaline, pterostigma and veins dark brown, except basal 0.6 of costa yellowish; metasomal tergites with median black bands, except tergite 2 with two subrounded black spots, black band on tergite 6 indistinct medially; ovipositor reddish brown; ovipositor sheath black.

Male. Unknown.

Comparision. The new species is distinguished from X. flaviceps Townes & Chiu by its short area superomedia (0.6x as long as wide versus 1.0x), shorter ovipositor sheath (0.25x hind tibia versus 0.47x), and the difference in the pattern of black spots and bands on legs and metasomal tergites.

Etymology. We name the new species in honor of MSc. Hien Thu Ngo, a Canadian entomologist who collected the holotype specimen.

Distribution. Currently known only from Ea So NR, Dak Lak Province, Central Highlands of Vietnam (Fig. 20).

Ecological notes. The single specimen was collected in evergreen forest.
