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).
