Type material. Holotype: ♀ (TMUC), Mazandaran province: Noor, Chamestan, Joorband (36°26′17.28″ N, 52°07′16.62″ E, 272m a.s.l.), 16. viii.2011.
Diagnosis: Vein r not curved and as long as vein 2RS; vein r-m well developed, areolet closed; pterostigma evenly brown or with an indistinct yellow spot basally; vein R1 5.00× as long as distance of vein R1 to vein 3RSb; T1 rugose, narrowed posteriorly, T1 length 1.60× its maximum width; hypopygium largely membranous; propodeum with a rugose median band and a complete median longitudinal carina; metafemur yellow; suture between T2 and T3 more or less developed, crenulated; T3+ yellow.
Description. Body length without ovipositor: 3.10 mm.
Head: Antenna slightly shorter than body; F 2/8/15 length/width: 3.50/2.50/1.25; mouthparts slightly elongated; gena, vertex and lower face densely and rather finely punctate; upper face smooth and setose; lower face with a weak medial longitudinal carina on upper half; clypeus punctured; labrum flat and smooth; malar space length 0.28× basal width of mandible (Figs 4a,b); OOL/OD/POL length: 0.15/0.08/ 0.10 mm (Fig. 4c).
Mesosoma: Anteromesoscutum length 0.80× its maximum width, densely punctate, posterior area with weak punctures to smooth; notauli not defined; scutoscutellar sulcus with visible crenulation; mesoscutellar disc with sparse punctures to smooth, shiny; side of mesoscutellar disc with wider crenulate depression; metanotum with coarse wrinkles on posterior; propodeum slightly wrinkle to smooth with median longitudinal band of rugosity, and a complete median longitudinal carina (Fig. 4e); side of pronotum rugose; propleuron smooth; prepectal carina absent; anterolateral and ventrolateral of mesopleuron punctate, medially smooth; metapleuron smooth with deep medial pit on anterior half (Fig. 4d).
Wings: Fore wing. length: 3.10 mm; pterostigma length/width: 2.20; pterostigma slightly shorter than vein R1; vein R1 5.00 × as long as distance of vein R1 to vein 3RSb; vein r as long as vein 2RS; vein 1M/m-cu length: 2.75; vein 3RSa long and distinct; areolet closed; vein 1-CUb slightly shorter than vein 1-CUa (Fig. 4f). Hind wing: vein M+CU/1-M length: 1.20; vein cu-a slightly curved; vanal lobe with fringe anteriorly and slightly on posterior, posterior margin partly straight (Fig. 4g).
Legs: Metacoxa laterally punctate; mesotibial inner spur slightly longer than outer, not reaching to posterior margin of mesobasitarsus; metafemur/metatibia/metabasitarsus/sum of other segments metatarsus length: 0.80/ 1.00/0.45/ 0.60 mm, respectively; metafemur length/width: 3.40; metatibial spurs length unequal, internal metatibial spurs/metabasitarsus length: 0.50 (Fig. 4d).
Metasoma: T1 curved, rugose, T1 length 1.60× its maximum width, T1 anterior half parallel-sided or sub parallel-sided and posterior half gradually narrowed posteriorly; T1 posterior width 2.60× T2 length medially; T2 rugose and transverse; T3/T2 length: 3.50; suture between T2 and T3 more or less developed, crenulated; T3+ smooth (Fig. 4h); ovipositor sheath very curved downwards, rather widened posteriorly, ovipositor sheath 0.80× as long as metatibia; hypopygium membranous and apically acute (Fig. 4d).
Colouration: Body black; labrum, mandibles, palpi, scape, propleuron, tegulae, parastigma, T3+ yellow; clypeus brown; legs almost yellow to brownish yellow (Fig. 4d); wings with brownish yellow setae; veins of wings brown; pterostigma evenly brown or with an indistinct yellow spot basally (Fig. 4f).
Etymology: From Latin "fulvus" (yellow) and "venter" (abdomen), referring to the mostly yellow dorsally metasoma.
Notes: This species runs in the key by van Achterberg (2002) to C. ruficornis (Nees, 1834), it differs from fulviventris sp. nov. as follows: in ruficornis vein r-m of fore wing indistinct and areolet open; vein r distinctly shorter than vein 2RS; T1 posterior width equal to T2 length medially; mesotibial inner spur almost twice than outer, reaching to posterior margin of mesobasitarsus. This species runs in the key by Kotenko (2007) to C. psarae (Wilkinson, 1927), it differs from C. fulviventris sp. nov. as follows: in psarae metasoma completely yellow; distal half of metacoxa black; distal parts of metatibia and metatarsus blackish brown; body length: 4.70 mm. This species runs in the key by Song et al. (2014) to couplet 8. two branches of the couplet 8 differ from fulviventris sp. nov. as follows: in longitergitus (first branch of the couplet) T1 sharply narrowed posteriorly; T1 and T2 largely smooth, T2 subtriangular. In the second branch of the couplet 8 propodeum strongly rugose; T1 distinctly rectangular and parallel-sided.
