Figs 19 , 20 Type material. Holotype . ♀, China, Jilin Prov., Tonghua, 1.VIII.1994, Lou Juxian, No. 976765 (ZJUH). Paratypes . 1♀, China, Liaoning Prov., Shenyang Dongling, 6.V.1994, Lou Juxian, No. 947493 (ZJUH); 1♂, China, Jilin Prov., Antu, 5-6.VIII.1994, Lou Juxian, No. 977054 (ZJUH). Diagnosis. This new species is very similar to B. (L.) fortipes (Wesmael, 1838), but can be separated from the latter by the following characters: third metasomal tergite smooth (coarsely sculptured in B. (L.) fortipes ); hind femur 3.5 x longer than its maximum width (2.5 times); fore wing vein SR1 2.2 x longer than vein 3-SR (1.5 times); setose part of ovipositor sheath distinctly shorter than hind tibia (as long as hind tibia + first and second of tarsus combined); body largely yellowish-brown (largely reddish-brown). Description. Holotype , ♀, length of body 2.9 mm, of fore wing 2.8 mm, of ovipositor sheath 0.4 mm. Head . Antenna with 25 segments; apical antennal segment acute, 2.3 x longer than its maximum width (Fig. 20l ); first flagellomere 2.2 x longer than wide, 1.1 and 1.2 x longer than second and third, respectively, the latter being 1.6 x longer than wide; malar suture rather weak, with some short setae; clypeus height: inter-tentorial distance: tentorio-ocular distance = 4: 12: 5; clypeus sparsely short setose; eye not emarginate (Fig. 20g ); face largely weakly granulate and with dense short setae laterally (Fig. 20g ); eye height: shortest distance between eyes: head width = 11: 15: 28; frons weakly granulate, weakly concave behind antennal sockets, with a rather weak median groove (Fig. 20h ); vertex smooth, with sparse short setae; shortest distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 5: 3: 7; temples subparallel-sided behind eyes (Fig. 20h ). Mesosoma . Length of mesosoma 1.4 x its height (Fig. 20c ); notauli only impressed anteriorly (Fig. 20d ); mesoscutum smooth, with sparse short setae along imaginary notaulic courses (Fig. 20d ); scutellar sulcus deep, moderately wide, with crenulae (Fig. 20d ); scutellum smooth, with some short setae posteriorly; metanotum moderately convex medially (Fig. 20d ); propodeum largely smooth, with medio-longitudinal carina beyond middle of propodeum (but absent anteriorly) and sparsely setose medially, with dense long setae laterally (Fig. 20e ). Wings . Fore wing (Fig. 20a ): SR1 not reaching tip of wing; SR1: 3-SR: r = 36: 16: 9; 1-SR+M more or less straight, 1.5 x longer than 1-M; 2-SR: 3-SR: r-m = 15: 16: 10; m-cu straight, 1.5 x longer than 2-SR+M; angle between 1-SR and C+SC+R about 80°; cu-a weakly postfurcal. Hind wing (Fig. 20b ): SC+R1: 2-SC+R: 1r-m = 14: 3: 5. Legs . Length of fore femur: tibia: tarsus = 21: 26: 27; length of hind femur: tibia: basitarsus = 24: 38: 13; length of femur, tibia and basitarsus of hind leg 3.5, 8.4 and 4.6 x their maximum width, respectively; hind tibial spurs 0.3 and 0.4 x as long as hind basitarsus. Metasoma . Length of first tergite 0.9 x its apical width; first tergite concave medio-basally, median area convex and smooth anteriorly, rugose posteriorly (Fig. 20j ); lateral grooves of first tergite moderately wide, with sparse weak crenulae (Fig. 20j ); second tergite with longitudinal striae, but laterally and posteriorly smooth (Fig. 20e ); median length of second tergite slightly shorter than that of third tergite; second metasomal suture moderately narrow, crenulate, more or less straight medially (Fig. 20e ); third to seventh tergites smooth (Fig. 20e ); setose part of ovipositor sheath 0.1 x as long as fore wing. Colour . Largely yellowish-brown (Fig. 19 ); antenna, eye, mandible apically, frons medially and postero-laterally, area surrounding stemmaticum, propleuron laterally and mesopleuron posteriorly blackish-brown (Fig. 20c, d, g, h ); propodeum posteriorly brown (Fig. 20e ); telotarsus and claws dark brown (Fig. 20f ); wing membrane pale infuscate, pterostigma dark brown and veins yellowish-brown to dark brown (Fig. 20a, b ). Variation . Length of body of female 2.9-3.6 mm, of fore wing of female 2.8-3.4 mm and of ovipositor sheath 0.4-0.5 mm; medio-longitudinal carina of propodeum nearly complete; fore wing vein m-cu 1.4-1.5 x longer than vein 2-SR+M; fore wing vein cu-a interstitial; length of first metasomal tergite 0.9-1.0 x its apical width; spot of head dorsally relatively paler; metasomal tergites largely yellow, first tergite anteriorly, laterally and posteriorly infuscate. Male . Length of body of male 3.1 mm, of fore wing of male 2.9 mm; antenna with 27 segments; pronotal side with an oblique transverse blackish-brown stripe. Biology. Unknown. Distribution. China (Jilin, Liaoning). Etymology. Named after the body colour: "flavus" is Latin for "yellow" and "adustus" is Latin for "brown" . Figure 19.
