Xanthopimpla porrecta sp. nov.

( Figs 1e, 3d, 5e, 7e, 9e, 11e, 13g, 15d)

Diagnosis. Scutellum conical with median point; first tergite elongate, 1.6x apical width; metasomal tergites each with two black spots; ovipositor sheath short, 0.27x length of hind tibia.

Description (Holotype female). Body length 18.5 mm, fore wing 15.0 mm, ovipositor sheath 1.0 mm. Head. Antennal flagellum thinner apically, first flagellomere 1.55x length of second; diameter of lateral ocellus 1.8x 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 0.6x 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, medially 0.5x as high as first flagellomere width; 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 extending to anterior margin; propodeum with strong, complete carinae, area superomedia as long as wide, propodeal spiracle elongate, 5.0x 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, 2.0x second tarsomere, third tarsomere 2.0x as long as wide, mid and hind tibiae with three bristles at apex, one bristle near apex. 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 0.25x length of vein cu-a.

Metasoma. First tergite 1.6x 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 sparse, coarse punctures; ovipositor sheath 0.27x hind tibia; ovipositor lower valve with ten apical ridges, upper valve with six transverse apical ridges.

Colour. Lemon yellow; antenna blackish, outer face of scape and pedicel yellowish; ocellar area and frons black; hind slope of vertex and occipital area marked with black; mesoscutum with median black spot joined posteriorly to black mark in front of scutellum, lateral black mark present at level of tegula; tegula black posteriorly; propodeum with black spot in first lateral area; hind trochanter marked with black; hind femur with black mark on posterior face, basal 0.15 of tibia black; wings hyaline with margin infuscate, pterostigma and veins black, except basal 0.6 of costa yellowish; metasomal tergites each with two black spots.

Male. Unknown.

Comparison. The new species differs from its congeners by the short ovipositor sheath and elongate first metasomal tergite.

Etymology. Named after Latin for 'stretched out', or 'long', after the elongate first tergite.

Distribution. Currently known only from Bac Can Province, Ba Ne NP, North Vietnam (Fig. 19).
