(Figs 2d, 4c, 6a, 8b, 10d, 12a, 14a, 15g, 17a)  
 Diagnosis. Occipital area black; median black mark on mesoscutum joined posteriorly to black mark in front of scutellum; lateral flange of scutellum high from base to apex; base of hind coxa with black spot anteriorly; metasomal tergites with sparse, fine punctures, black spots on tergite 3 almost impunctate; ovipositor lower valve with five low, vertical ridges apically; ovipositor sheath 1.55x hind tibia.   
 Description (Holotype female). Body length 10.0 mm, fore wing 9.0 mm, ovipositor sheath 3.3 mm. Head. First antennal flagellomere 1.5x length of second; diameter of lateral ocellus 1.1x ocellar-ocular distance; frons polished; face 0.95x as high as wide, with moderate-sized to large punctures, pubescent; clypeus 0.6x as high as wide, apical margin thin and emarginate; malar space about 0.3x basal width of mandible.   
 Mesosoma. Epomia short; lower anterior corner of pronotum subrounded, about 95°; mesoscutum with moderately dense, long hairs; notaulus present anteriorly, ending before half distance to anterior level of tegula; scutellum convex, pubescent, lateral carina forming high flange from base to apex, medially half as wide as first flagellomere width; mesopleuron with sparse, fine punctures on upper half, large, dense punctures at level of sternaulus, pubescent; sternaulus present on posterior half of mesopleuron; epicnemial carina present on lower half, postpectal carina forming high, triangular flange with deep median notch; metapleuron polished, submetapleural carina strong; propodeum with area superomedia 0.6x as long as wide, bounded by strong carinae; propodeal spiracle elongate, 3.0x as long as wide, pleural area with long, dense hairs in front of spiracle. Hind leg with femur 2.15x as long as wide, 0.9x length of tibia, hind basitarsus 0.3x length of tarsus, 1.8x second tarsomere, third tarsomere 1.5x as long as wide; mid tibia with three subapical, four apical stout bristles; hind tibia with three subapical, three apical stout bristles; 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 0.6x length of vein cu-a, vein 1 A absent distally.   
 Metasoma. First tergite 1.2x as long as apical width; dorsolateral carina present basally, median longitudinal carina ending before shallow oblique groove; metasomal tergites with sparse, fine punctures, black spots on tergite 3 almost impunctate; ovipositor decurved, with five low vertical ridges apically; ovipositor sheath 1.55x hind tibia.   
 Colour. Lemon yellow; antenna black, outer side of scape, pedicel, first two flagellomeres yellow; black ocellar area extending to frons and joined posteriorly to black area on hind slope of head and occipital area; mesoscutum with median black mark elongate, joined posteriorly to black mark in front of scutellum, lateral black mark joined to lateral ridge of mesoscutum; tegula black posteriorly; propodeum with black band basally; mid leg with basal 0.2 and median part of tibia, base of basitarsus, fourth and fifth tarsomeres black; base of hind coxa with black spot on anterior face; trochanter marked with black, hind femur with black marks on anterior and posterior faces; basal 0.2 of hind tibia black, median part of hind tibia with anterior and posterior black marks; hind tarsus black; wings hyaline, margins infuscate, pterostigma and veins dark brown, except basal 0.7 of costa yellowish; tergites 1–6 each with black spots, tergite 7 with black band.   
 Male. Unknown.   
 Comparison. The new species can be distinguished from X. attenuata attenuata Townes & Chiu in the Philippines, by its longer ovipositor sheath (1.55x hind tibia versus 1.25x) and the normally proportioned ovipositor (not distinctly slender), with five low apical ridges. Moreover, the new species has sparser, fine and small punctures on the upper half of the mesopleuron, denser punctures on the mesoscutum and the entirely black hind tarsus.   
 Etymology. We name this species after Dr Shui-Chen Chiu, in honour of her great work on the taxonomy of Xanthopimpla.   
 Distribution. Currently known only from Chu Yang Sin NP, Dak Lak Province, Central Highlands of Vietnam (Fig. 19).   
 Ecological notes. The single known specimen was collected in evergreen forest.   
 Material examined. Holotype: ♀ (RMNH), Dak Lak, Chu Yang Sin NP, 800–940 m a.s.l, 02–10.vi.2007, C. v. Achterberg & R. de Vries leg.
