Diagnosis. The new species resembles the European P. brevicornis Horstmann in that both species have the temple short ( Fig. 4 ), thyridia slightly elongate ( Fig. 19 ), and the ovipositor sheath distinctly shorter than the first tergite ( Fig. 18 ). But P. vulnificus sp. n. may be recognised by the very slender flagellomeres ( Fig. 5 ), and the longer body (about 4.0 mm in P. vulnificus sp. n. and about 3.0 mm in P. brevicornis ). The new species also differs from P. brevicauda Horstmann by the shorter temple ( Fig. 4 ) and entirely yellow-brown legs.

Description. Female. Body length 4.15 mm.

Head strongly and rather linearly narrowed behind eyes in dorsal view ( Fig. 4 ), temple 0.62 times as long as eye width ( Fig. 4 ). Flagellum of antenna with 17 segments, filiform; all flagellomeres, except the basal and apical ones, 1.8-2.0 times as long as wide ( Fig. 5 ). Upper tooth of mandible distinctly longer than lower tooth. Malar space half as long as basal width of mandible. Oral carina strong, distinctly raised after juncture with occipital carina. Clypeus weakly and evenly convex, almost entirely smooth, with fine, sparse punctures in upper half. Face, frons and vertex distinctly granulate, without distinct punctures. Temple with more shallow granulation, very finely punctate.

Mesoscutum granulate and rather densely punctate. Sternaulus long, crenulate, upcurved anteriorly ( Fig. 16 ). Mesopleuron finely granulate to smooth, more or less densely punctate, smooth and impunctate above sternaulus, punctate-rugulose in upper anterior corner of mesopleuron ( Fig. 16 ). Basal area of propodeum indistinct, with strong longitudinal wrinkles, 0.43 times as long as apical area ( Fig. 17 ). Propodeal spiracle separate from pleural carina by about 1.5 diameters of spiracle. Dorsolateral area of propodeum finely granulate, sparsely and finely punctate; apical area uneven to rugulose.

Fore wing length 3.25 mm. First section of radial vein longer than width of pterostigma. Metacarp almost reaching apex of fore wing. Second recurrent vein postfurcal, unpigmented in its anterior part. Nervellus of hind wing weakly reclivous. Tarsal claws not pectinate.

First tergite length 0.98 mm, posterior width 0.26 mm; tergite slender, weakly arched ( Fig. 18 ), smooth; petiole very finely striate dorso-posteriorly and laterally in front of glymma. Glymma in anterior 0.6 of first tergite, medium-sized, joined by a distinct furrow to ventral part of postpetiole. Th yridia somewhat elongate ( Fig. 19 ). Second tergite length 0.42 mm. Ovipositor upcurved, with two rounded, dorsal, subapical teeth and with one small ventral tooth ( Figs 6 , 20 ); sheath 0.8 mm long, 0.82 times as long as first tergite ( Fig. 18 ).

Coloration. Body black. Palpi, mandible (excepting teeth) and legs yellow-brown (hind tarsus infuscate). Clypeus in its lower 0.4 and tegula brownish. Scape and pedicel of antenna yellowish. Pterostigma dark brown. Metasoma behind first segment yellowbrown, tergites 2-5 extensively blackish dorsally.

Male unknown.

Type material. Holotype female, China, Ningxia Hui Autonomous Region, Liupanshan , 35°24’ N, 106°23’ E, 1820 m, 11.VIII.2005, coll. M.-L. Sheng ( GSFPM).

Etymology. From the Latin vulnificus (wounding).
