Material examined.

Holotype. ♀, China, Liaoning prov., Shenyang, IX.1955, No. 6503222 (ZJUH).

Diagnosis.

Body brownish yellow. Hind leg black. Fore wing with a small isolated stigmal spot. Pterostigma yellow. Propodeum without a closed areola. Vein cu-a of fore wing almost interstitial; Length of first tergite 1.8 times its apical width. First tergite entirey longitudinally carinate. length of second tergite 1.2 times its width. Ovipositor sheath not widened, distinctly shorter than body.

Description.

Holotype, ♀, length of body 15.1 mm, of fore wing 13.5 mm.

Head. Antennal segments missing; in dorsal view length of eye twice temple; POL:OD:OOL = 8:6:14; occipital flange large, its ventral margin convex bellow; face shiny smooth with sparse punctures; frons smooth, vertex smooth, sparsely setose.

Mesosoma. Length of mesosoma 1.5 times its height; subpronope large and deep; side of pronotum smooth; area near lateral carina of mesoscutum smooth; lateral lobes of mesoscutum almost smooth; notauli deep, smooth, scutellar sulcus 0.5 times as long as dorsal face of scutellum and with 3 carinae; scutellum smooth, distinctly convex anteriorly and sloping posteriorly; mesopleuron above precoxal sulcus shiny and smooth, below precoxal sulcus shiny with minute punctures; precoxal sulcus narrow, similar to a smooth groove; metapleuron smooth; propodeum with a subbasal transverse carina, without a closed areola, spiracle large, elliptical, close to lateral carina and 2.8 times as long as wide; lateral carina of propodeum completely.

Wings. Fore wing: second submarginal cell pentagonal, narrow anteriorly, with rather long ramellus, 1.4 times as long as vein 2-SR (14:10); r:3-SR:SR1 = 9:4:70; 2-SR:3-SR:r-m = 14:4:14; vein cu-a almost interstitial. Hind wing: vein 2-SR+M transverse; vein M+CU 0.9 times as long as 1-M; surroundings of vein cu-a sparsely setose.

Legs. Length of hind femur, tibia and basitarsus 4.9, 8.3 and 8.6 times their width, respectively; hind coxa smooth; hind femur with short and dense setosity; outer side of apical third of middle tibia with a row of 4 pegs and cluster of 4 pegs at apex; outer side of apex of hind tibia with a cluster of 6 pegs; length of outer and inner spurs of middle tibia 0.4 and 0.5 times middle basitarsus, respectively; length of outer and inner spurs of hind tibia 0.3 and 0.4 times hind basitarsus, respectively.

Metasoma. First tergite moderately long, widened apically, 1.8 times its apical width; first tergite entirely longitudinally striate; dorsal carinae of first tergite strong, diverging apically; second tergite as long as third tergite, deep striate transverse groove on apical third; third tergite with parallel striae but smooth on extreme apex; striate transverse groove on apical third wide; remainder of metasoma smooth with sparse setae apically; ovipositor sheath broken; ovipositor about as long as fore wing.

Colour. Brownish yellow; fore wing with a brown stigmal spot; apical third of wings infuscate and basal two-thirds yellow; parastigma yellow; hind leg black; metasoma black, but basal half of first and second tergites and ventral part of first-third metasomal segments brownish yellow.

Male. Unknown.

Distribution.

East Palaearctic region. China (Liaoning).

Biology.

Unknown.

Remarks.

This new species is very similar to B. matsumurai Watanabe, but differs by having no closed areola on the propodeum; the fore wing with a small isolated stigmal spot; the hind leg black; and vein cu-a of the fore wing almost interstitial.

Etymology.

From “Shenyang”, the type locality of the species.
