Mesoleius View in CoL View at ENA (? Campodorus ) faciator Kasparyan, 2001
Figs 11–16 View Figs 11–16
Diagnosis
Head, mesoscutum ( Fig. 13 View Figs 11–16 ), mesopleuron, metasomal tergites 1–3 ( Fig. 16 View Figs 11–16 ) shagreened, almost without punctures. Clypeus approximately 3.3 × as wide as long, smooth, shiny. Lateral portion of propodeum ( Fig. 15 View Figs 11–16 ) with long whitish yellow setae; median longitudinal carinae strongly converge medially. Face and clypeus whitish yellow. Metasomal tergites almost entirely black.
Differential diagnosis
In main peculiarities of coloration and most other diagnostic characters the Chinese specimens correspond to the holotype of Mesoleius faciator Kasparyan, 2001 ( Russia, Chita Prov.), but differ in dense long pubescence of lateral parts of the propodeum; in having more antennal segments (39 flagellomeres) and smaller body size (fore wing 6.6 mm long); the holotype of M. faciator has 36 flagellomeres and fore wing is 8.1 mm long. Although described in the genus Mesoleius, Kasparyan (2001) noted that M. faciator occupied an intermediate position between Campodorus and Mesoleius .

Description
Female
MEASUREMENTS. Body length approximately 11.6 mm. Fore wing length approximately 6.8 mm. Ovipositor sheath length approximately 0.4 mm.
HEAD. Face ( Fig. 12 View Figs 11–16 ) approximately 1.8 × as wide as long, shagreened, almost flat, with dense yellowish white setae; upper margin with median small tubercle. Clypeus approximately 3.3 × as wide as long, smooth, shiny, with sparse brown setae; apical margin sharp, subapical portion distinctly convex ( Fig. 12 View Figs 11–16 ). Mandible with sparse indistinct shallow punctures and brown setae; upper tooth slightly wider, longer than lower tooth. Malar area granulated; malar space approximately 0.5 × as long as basal width of mandible. Gena and vertex almost shagreened. Posterior portion of gena distinctly convergent posteriorly. Postocellar line approximately 0.9 × as long as ocular-ocellar line. Antenna with 39 flagellomeres; ratio of length from first to fifth flagellomeres approximately: 1.6:1.3:1.2:1.1:1.0. Occipital carina complete, lower end reaching hypostomal carina distinctly above base of mandible.
MESOSOMA. Pronotum ( Fig. 14 View Figs 11–16 ) roughly granulated, lateromedian portion of lateral concavity with fine indistinct oblique wrinkles; subdorsal portion with few distinct oblique wrinkles. Mesoscutum ( Fig. 13 View Figs 11–16 ) and scutellum distinctly shagreened, with sparse fine punctures. Notauli reaching middle of mesoscutum. Scutoscutellar groove smooth. Postscutellum transverse, almost shiny, concave at base. Mesopleuron ( Fig. 14 View Figs 11–16 ) roughly indistinctly shagreened; speculum shiny, smooth; area in front of speculum with fine indistinct punctures. Upper end of epicnemial carina reaching to 0.7 distance to subtegular ridge. Metapleuron ( Fig. 14 View Figs 11–16 ) evenly slightly convex, distinctly shagreened; lower posterior portion with irregular oblique wrinkles. Claw simple. Ratio of length of hind tarsomeres from first to fifth: 4.3:2.1:1.7:1.0:1.4. Wings brownish, hyaline. Fore wing with vein 1cu-a distal to M&RS by 0.2 × length of 1cu-a. Postnervulus intercepted below middle. Hind wing vein 1-cu 1.5 × as long as cu-a. Propodeum ( Fig. 15 View Figs 11–16 ) shagreened, lateral portion with long whitish yellow setae; median longitudinal and posterior transverse carinae complete, strong. Median longitudinal carinae strongly narrowed medially, area between them shiny. Area petiolaris shiny, with irregular longitudinal wrinkles. Propodeal spiracle almost circular.
METASOMA. Anterior three metasomal tergites ( Fig. 16 View Figs 11–16 ) shagreened. First tergite 1.4 × as long as posterior width, strongly and evenly tapered to base; posterior margin slightly smooth; dorsal median carina reaching to 0.4 length of first tergite; dorsolateral and ventrolateral carinae complete; spiracle small, circular, slightly convex, located at anterior 0.4 of first tergite. Second tergite ( Fig. 16 View Figs 11–16 ) 0.8 × as long as anterior width, 0.6 × as long as posterior width. Third tergite 0.55 × as long as posterior width, with more or less distinct median transverse depression ( Fig. 16 View Figs 11–16 ). Fourth and subsequent tergites with fine short indistinct transverse rugae. Ovipositor sheath ( Fig. 11 View Figs 11–16 ) about 4.0 × as long as wide, parallel-sided, rounded posteriorly.
COLORATION ( Fig. 11 View Figs 11–16 ). Black, except for following: antennae darkish brown dorsally, brown ventrally. Face, clypeus whitish yellow; mandible except teeth, maxillary palpi, labial palpi, malar area, upperposterior corners of pronotum, tegulae, subtegular ridge, posterior margins of tergites 3–7 slightly yellowish white. Fore and middle coxae, except for black bases, their trochanters, apex of hind coxa and hind trochanters ventrally yellow. All femora red to brown red. Fore and middle tibiae and tarsi almost evenly yellowish. Basal 0.6 of hind tibia mainly yellow. Pterostigma and veins black brown. Sternites 2–5 whitish yellow, sublateral parts broadly black ( Fig. 11 View Figs 11–16 ).
