Figs 35–41
Diagnosis
Upper median area of face (Fig. 36) with dense distinct punctures, lateral portion distinctly shagreened. Clypeus smooth, shiny, 3.2 × as wide as long. Hind wing vein 1-cu approximately 4.0 × as long as cu-a. Anterior and posterior transverse carinae of propodeum (Fig. 39) absent. Median longitudinal carinae evenly narrowed anteriorly, area between them smooth, shiny (Fig. 39). Face black, lower-lateral spots yellowish white (Fig. 36). Flagellum brown. Scutellum and postscutellum reddish brown.
Differential diagnosis
The new species is similar to C. ciliatus (Holmgren, 1857), but can be distinguished from the latter by the following combinations of characters: median longitudinal carinae of propodeum (Fig. 39) evenly divergent posteriorly; areas superomedia and petiolaris completely confluent. Ovipositor sheath (Fig. 41) approximately 3.5 × as long as its maximum width, almost parallel. Lower lateral portion of face (Fig. 36) with large yellow spots. Hind tarsus almost entirely black. Campodorus ciliatus: median longitudinal carinae of propodeum strongly converging medially; areas superomedia and petiolaris separated by transverse carina. Ovipositor sheath 4.2 × as long as maximum width, slightly expanding posteriorly. Face entirely black. At least basal halves of hind basal three tarsomeres white.
Etymology
The specific name is derived from the median area of the propodeum being smooth.

Description
Female
MEASUREMENTS. Body length approximately 8.2 mm. Fore wing length approximately 7.1 mm. Ovipositor sheath length approximately 0.4 mm.
HEAD. Inner margins of eyes slightly convergent ventrally, slightly concave near antennal sockets. Face (Fig. 36) approximately 1.8 × as wide as long, shagreened, upper-median portion with dense distinct punctures; upper margin with median small tubercle. Clypeus approximately 3.2 × as wide as long, apical median portion distinctly convex; apical median margin distinctly concave; shiny, with very sparse punctures and brown setae. Mandible with relately sparse punctures and yellow brown setae; upper tooth same length and width as lower tooth. Malar area granulate; malar space approximately 0.4 × as long as basal width of mandible. Gena and vertex (Fig. 37) shagreened. Hind portion of gena evenly convergent posteriorly. Lateral and posterior portion of vertex with fine punctures. Postocellar line approximately 0.8 × as long as ocular-ocellar line. Frons shagreened, slightly concave medially. Antenna with 35 flagellomeres; ratio of length from first to fifth flagellomeres approximately: 1.7:1.2:1.0:1.0:1.0. Occipital carina complete, lower end reaching hypostomal carina distinctly above base of mandible.
MESOSOMA. Anterior margin of pronotum (Fig. 38) slightly shagreened, with longitudinal fine wrinkles; upper portion of lateral concavity with distinct transverse wrinkles, lower portion with strong oblique longitudinal wrinkles; upper-posterior portion shiny, with fine punctures. Mesoscutum with dense fine punctures, distance between punctures 0.2–2.5 × diameter of puncture; sparser on lateral portion, distance between punctures 1.0–4.0 × diameter of puncture. Anterior half of notauli distinctly present. Scutoscutellar groove almost shiny, lateral portion with short wrinkles. Scutellum and postscutellum with fine punctures. Postscutellum transverse. Mesopleuron (Fig. 38) with dense even punctures, distance between punctures 0.5–3.0 × diameter of puncture; speculum and adjacent area smooth, shiny, without punctures. Upper end of epicnemial carina approximately reaching to 0.5 distance to subtegular ridge. Metapleuron (Fig. 38) evenly convex, with dense punctures, distance between punctures 0.5– 2.0 × diameter of puncture; with dense short gray-brown setae. Claw simple. Ratio of length of hind tarsomeres from first to fifth approximately: 5.3:2.5:1.8:1.0:1.7. Wings gray, hyaline. Fore wing with vein 1cu-a distal to M&RS approximately by 0.3 × length of 1cu-a. Postnervulus intercepted at lower 0.45. Hind wing vein 1-cu approximately 4.0 × as long as cu-a. Propodeum (Fig. 39) shiny, with dense even punctures and gray white setae except smooth median longitudinal area; without transverse carinae. Median longitudinal carinae evenly narrowed anteriorly. Area petiolaris with irregular weak wrinkles. Propodeal spiracle circular, located at anterior 0.3 of propodeum.
METASOMA. Tergites (Fig. 40) almost shiny. First tergite approximately 1.3 × as long as posterior width, with sparse fine punctures; dorsal median carina reaching beyond middle; spiracle slightly convex, circular, located slightly anterior to middle of tergite. Second and subsequent tergites (Fig. 40) with fine short gray brown setae. Second tergite approximately 0.7 × as long as anterior width, 0.5 × as long as posterior width. Ovipositor sheath (Fig. 41) approximately 3.5 × as long as its maximum width, almost parallel. Ovipositor (Fig. 41) straight.
COLORATION (Fig. 35). Black, except for following: ventral profiles of scape and pedicel, flagellum brown; lower-lateral portion of face, mandible except teeth, maxillary palpi, labial palpi, fore and middle coxae mostly, all trochanters, basal half of hind tibia except basal end, upper-posterior corners of pronotum, anterolateral spots on mesoscutum, tegulae, subtegular ridge, posterior margins of tergites 1–7 yellowish white; clypeus, fore and middle femora yellowish red, tibia and first three tarsomeres whitish yellow; hind coxa red, femur red with blackish-brown apical 0.25; scutellum and postscutellum reddish brown; pterostigma brownish black; veins black brown. Sternites 1–3 and anterior and posterior portion of 4 yellowish white. Median portion of sternite 4 and sternites 5–6 black.
