Xanthopimpla flavafemora sp. nov. ( Figs 2a, 3f, 5f, 7f, 9f, 11f, 13e, 15f)

Diagnosis. Scutellum conical with median point, lateral flange higher apically than medially; tergite 3 moderately densely punctate; metasomal tergites each with two black spots; ovipositor sheath 0.8x length of hind tibia.

Description (Holotype female). Body length 17.0 mm, fore wing 15.0 mm, ovipositor sheath 3.0 mm. Head. Antennal flagellum thinner apically, first flagellomere 1.55x length of second; diameter of lateral ocellus 1.9x ocellar-ocular distance; frons smooth; face 0.8x as high as wide, with low vertical curved carina beneath each antennal socket, between carinae densely, coarsely punctate; clypeus 0.55x as high as wide, apical margin concave medially; malar space about 0.2x basal width of mandible.

Mesosoma . Epomia short; lower anterior corner of pronotum rounded, making obtuse angle of 100°; mesoscutum with sparse hairs; notaulus shallow on anterior 0.2 of mesoscutum, extending nearly to anterior level of tegula; scutellum conical, with median point, pubescent, lateral carina extending to apex, forming lateral flange higher apically than medially; mesopleuron with sparse, minute punctures on upper half, dense, coarse punctures on lower half, epicnemial carina present on lower half of mesopleuron, postpectal carina medially forming low flange; metapleuron subpolished, submetapleural carina complete; pleural carina weaker before meeting anterior margin; pleural part of propodeum subdivided by posterior transverse carina; propodeum with strong, complete carinae, area superomedia as long as wide, propodeal spiracle elongate, 5.5x as long as wide, in front of spiracle with tubercle swelling. Hind leg with femur 2.4x longer than wide, 0.8x length of tibia, basitarsus 0.3x length of tarsus, 1.7x second tarsomere, third tarsomere 1.8x as long as wide, mid tibia with three apical bristles; hind tibia with two apical bristles. Fore wing with vein 2 rs-m 0.8x 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 1.25x as long as apical width, median longitudinal carina ending before oblique groove, dorsolateral carina strong from base to spiracle, weak from spiracle to apex; tergite 3 with moderately dense, coarse punctures; ovipositor sheath 0.8x hind tibia; ovipositor lower valve with nine apical ridges, upper valve with five shallow transverse apical ridges.

Colour. Lemon yellow; antenna black, scape, pedicel and first flagellomere yellowish beneath; ocellar area and frons black; hind slope of vertex and occipital area largely black; mesoscutum with median black stripe joined posteriorly to black mark in front of scutellum, two lateral black marks present at level of tegula, not connected to lateral ridge of mesoscutum; tegula black posteriorly; propodeum with black spot in first lateral area; mid leg with basal 0.2 of tibia and base of basitarsus black; hind trochanter marked with black; basal 0.15 of tibia and base of basitarsus black; wings hyaline with infuscate margin, pterostigma and veins black, except basal 0.6 of costa yellowish; metasomal tergites each with two black spots, black spots on tergite 6 small, about 0.25x width of black spots on tergite 5.

Male. Unknown

Comparison. Xanthopimpla flavafemora sp. nov. differs from X. pedator and X. brachyparea by its more sparsely punctate tergite 3 and its entirely yellow hind femur. The new species further differs from X. brachyparea by the presence of black spots on tergites 2 and 6.

Etymology. Named after the entirely yellow femora.

Distribution. Currently known only from Nghe An, Pu Mat NP, Central of Vietnam (Fig. 19).
