Figs 1–10
Diagnosis
Clypeus (Fig. 2) approximately 2.2 × as wide as long, shiny, with texture different from face. Speculum large, shiny, smooth (Fig. 6). Metapleuron with texture different from mesopleuron, with dense indistinct punctures. Median longitudinal carinae of propodeum complete, almost parallel. Ovipositor sheath (Fig. 10) approximately 3.6 × as long as its width, evenly widened posteriorly. Hind coxa yellowish white dorsally, brownish red ventrally. Metasomal tergites and sternites 5–6 (Figs 1, 8–10) broadly white on posterior margins.
Differential diagnosis
The new species is similar to C. ciliatus (Holmgren, 1857), but can be distinguished from the latter by the following combination of characters: median longitudinal carinae of propodeum (Fig. 7) almost parallel; ovipositor sheath (Fig. 10) without particularly long setae; hind coxa yellowish white dorsally, brownish red ventrally; posterior margin of metasomal tergites (Figs 8–10) widely white. Hind tibia pale in basal 0.3, blackish at extreme base and in apical half. Campodorus ciliatus: median longitudinal carinae of propodeum strongly narrowed medially; apical portion of ovipositor sheath at apex with a few particularly long setae; hind coxa entirely red; metasomal tergites almost entirely black. Hind tibia predominantly pale rufous, not darkened at base, and brownish in apical 0.33.
Another Oriental species, C. orientalis Kasparyan, 1998, differs from the new species in having the mesothorax and hind coxa completely red, first flagellomere strongly elongate, 1.9 × as long as second, and areas of the propodeum before the level of the spiracle obliterated.
Etymology
The specific name is derived from the white bands on the hind margins of the metasomal tergites.

Description
Female
MEASUREMENTS. Body length 6.9–8.1 mm. Fore wing length 5.5–6.4 mm. Ovipositor sheath length 0.4– 0.5 mm.
HEAD. Inner orbits parallel. Face (Fig. 2) approximately 1.7 × as wide as long, shagreened, with shallow indistinct punctures; upper margin with median small tubercle. Clypeus approximately 2.2 × as wide as long, transversely convex, shiny, with sparse yellowish brown setae. Mandible with large shallow sparse punctures and brown setae; upper tooth slightly longer than lower tooth. Malar space slightly shagreened, about 0.4 × as long as basal width of mandible. Gena (Fig. 3) slightly shagreened, hind portion almost shiny, evenly convergent backward. Vertex (Fig. 4) with texture as that of gena, lateral portion with indistinct fine punctures. Postocellar line approximately 0.8 × as long as ocular-ocellar line. Frons almost flat, shagreened. Antenna with 33–34 flagellomeres; ratio of length from first to fifth flagellomeres approximately: 1.7:1.1:1.0:1.0:1.0.
MESOSOMA. Anterior portion of pronotum (Fig. 6) smooth, shiny; lateral concavity with irregular short transverse wrinkles; upper-posterior portion with distinct, fine punctures. Mesoscutum (Fig. 5) shiny, median portion with relatively dense punctures, distance between punctures 0.5–2.5 × diameter of puncture; sparser on lateral portion, distance between punctures 1.0–4.0 × diameter of puncture. Notauli distinct in anterior 0.5 of mesoscutum, slightly convergent posteriorly (Fig. 5). Scutellum with dense fine punctures. Postscutellum almost rectangular, with indistinct shallow punctures. Anterior and lower portion of mesopleuron (Fig. 6) smooth with relatively dense punctures, distance between punctures 0.2– 2.0 × diameter of puncture; speculum and surrounding area shiny, smooth, without punctures. Upper end of epicnemial carina approximately reaching 0.4 distance to subtegular ridge. Metapleuron with dense indistinct punctures and gray-brown setae (Fig. 6). Claw simple. Ratio of length of hind tarsomeres from first to fifth approximately: 5.2:2.3:1.8:1.0:1.4. Wings slightly brownish, hyaline. Fore wing with vein 1cu-a distal to M&RS by approximately 0.5 × length of 1cu-a. Postnervulus intercepted slightly below middle. Hind wing vein 1-cu 1.5–2.0 × as long as cu-a. Propodeum (Fig. 7) with irregular indistinct rugae; median longitudinal and posterior transverse carinae complete, strong. Median longitudinal carinae very slightly converging medially, area between them shiny. Posterior half of area petiolaris with irregular longitudinal wrinkles. Propodeal spiracle almost circular.
METASOMA. First tergite (Fig. 8) approximately 1.2 × as long as posterior width, strongly and evenly narrowed to base, slightly shagreened; dorsal median carinae reaching to middle; spiracle small, circular, located approximately at anterior 0.4 of first tergite. Second and subsequent tergites (Figs 8–10) distinctly shagreened, with short brownish gray setae. Second tergite (Fig. 9) approximately 0.6 × as long as apical
width. Ovipositor sheath (Fig. 10) approximately 3.6 × as long as its width, evenly widened posteriorly. Ovipositor (Fig. 10) with distinctly wide subapical dorsal notch.
COLORATION (Fig. 1). Black, except for following: apical half of scape ventrally and apical margin of pedicel more or less yellow brown. Clypeus, small median spot and two spots in lower corners of face (Fig. 2), mandible except teeth, maxillary palpi, labial palpi, tegulae, subtegular ridge, scutellum, postscutellum, fore and middle coxae and parts of tarsi, hind coxa dorsally, all trochanters, and subbasal portions of hind tibia whitish yellow. Fore and middle legs except coxae and parts of tarsi brownish yellow. Hind coxa ventrally and hind femur reddish. Posterior portions of metasomal tergites white. Sternites 2-4 broadly whitish in median part, sternites 5 and 6 black with anterior and posterior margins widely white.
Remarks
Campodorus albilineatus sp. nov. is the only species known from the Oriental part of China.
