Xanthopimpla oriole sp. nov.

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

Diagnosis. Face as high as wide; hind slope of vertex and occipital area entirely yellow; hind femur with large black stripe posteriorly; hind tibia with one apical, one preapical stout bristle; metasomal tergites densely, finely punctate; ovipositor sheath 0.33x hind tibia; ovipositor straight with seven apical ridges.

Description (Holotype female). Body length 8.5 mm, fore wing 7.3 mm, ovipositor sheath 0.8 mm. Head. First antennal flagellomere 1.4x length of second; diameter of lateral ocellus 1.3x ocellar-ocular distance; frons polished; face as high as wide, finely punctate, pubescent; clypeus 0.6x as high as wide, apical margin thin and emarginated; malar space about 0.3x basal width of mandible.

Mesosoma . Epomia short; mesoscutum with dense, short hairs, notaulus present on anterior 0.25 of mesoscutum, ending before anterior level of tegula; scutellum convex, pubescent, lateral carina forming low flange; upper half of mesopleuron polished, impunctate, lower half with fine punctures, pubescent, epicnemial carina present on lower half, postpectal carina medially forming wide and low flange; metapleuron polished; propodeum with area superomedia 0.8x as long as wide; propodeal spiracle elongate, 4.0x as long as wide. Hind leg with femur 2.3x as long as wide, 0.8x length of tibia, hind basitarsus 0.3x length of tarsus, 2.0x second tarsomere, third tarsomere 1.4x as long as wide; mid tibia with three bristles near apex, two bristles at apex; hind tibia with one bristle near apex, one bristle 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 0.3x length of vein cu-a.

Metasoma. First tergite 1.15x as long as apical width; dorsolateral carina weakly present, median longitudinal carina strong, extending to oblique groove; tergite 2 onwards densely finely punctate; ovipositor straight with seven ridges apically, ovipositor sheath 0.33x length of hind tibia.

Colour. Lemon yellow; antenna dark brown, outer side of scape and pedicel yellow; ocellar area black; mesoscutum with three continuous black spots medially and black spot in front of scutellum; tegula brown, transparent posteriorly; propodeum with black spot in first lateral area; basal 0.15 of mid tibia and base of mid basitarsus black; hind leg with trochanter black, femur with black stripe on posterior face, tibia with large basal, narrow apical black bands, base of basitarsus and fifth tarsomere black; wings hyaline with infuscate margins, pterostigma and veins dark brown, except costa yellowish; tergites 1 and 7 with black bands, tergites 3–6 each with two black spots.

Male. Similar to female, slightly smaller.

Comparision. The new species is distinguished from X. flaviceps Townes & Chiu by its hind tibia with only one preapical bristle (versus 2–3), the area superomedia entirely yellow, and the ovipositor lower valve has seven apical ridges (versus four ridges).

Etymology. Named after the beautiful yellow and black male of the Golden Oriole.

Distribution. Currently known only from Phong Dien NR, Thua Thien-Hue Province, Central Vietnam (Fig. 19).

Ecological notes. The specimens were collected in lowland evergreen forest.
