Holotype. ♀, Guangdong prov., Longmen Nankunshan, 14-15.VII.2003, Xu Zaifu, No. 20053640 ( ZJUH). Paratypes: 2♂♂, same data, but No. 20053619, 20053641 ( ZJUH); 1♀, Guangdong prov., Ruyuan Nanling, 23.VII.2003, Xu Zaifu, No. 20049043 ( ZJUH); 1♀, same data, but 18.VII.2003, No. 20049357 ( ZJUH); 2♀♀, Guangdong prov., Meizhou Fengxi, 29.VII.2003, Chen Jujian, No. 20048502, 20048677 ( ZJUH).


Body black. Antenna, hind coxa and hind femur yellowish brown. Area below face and clypeus ivory. Wing membrane evenly dark brown. Vein cu-a of fore wing antefurcal. Length of hind femur 5.2-5.3 times as long as wide. Length of first tergite 2.7-2.8 times its apical width. Ovipositor sheath ribbon-shaped widened.


Holotype, ♀, length of body 9.0 mm, of fore wing 7.0 mm.

Head. Antennal segments 45, length of third segment 1.15 times fourth segment, length of third, fourth and penultimate segments 2.5, 2.2 and 1.7 times their width, respectively; length of maxillary palp 0.7 times height of head; in dorsal view head transverse and 1.3 times as wide as mesoscutum; length of eye 2.2 times temple; POL:OD:OOL = 9:6:13; antennal sockets not tubular; occipital flange sharp; malar space 1.8 times as long as basal width of mandible; face shiny with sparse fine punctures, frons and vertex smooth.

Mesosoma. Length of mesosoma 1.5 times its height; subpronope large and deep; side of pronotum smooth; area near lateral carina of mesoscutum crenulate; lateral lobes of mesoscutum almost smooth, sparsely finely punctate anteriorly; middle lobe with sparse fine punctures; notauli deep, smooth; scutellar sulcus 0.5 times as long as dorsal face of scutellum and with one carina; scutellum convex anteriorly, smooth and with long setae; mesopleuron above precoxal sulcus largely smooth; mesopleuron below precoxal sulcus setose, with sparse fine punctures; precoxal sulcus wide, shallow and distinctly crenulate; metapleuron mainly smooth with long setae; propodeum setose, with a strong transverse carina subbasally, rugose posteriorly; spiracle medium-sized, round, 1.8 times as long as wide.

Wings. Fore wing: second submarginal cell pentagonal, narrow anteriorly, with rather long ramellus, 0.9 times as long as vein 2-SR (14:15); r:3-SR:SR1 = 8:3:72; 2-SR:3-SR:r-m = 15:3:15; vein cu-a antefurcal. Hind wing: vein 2-SR+M transverse; vein M+CU 0.5 times as long as 1-M; surroundings of cu-a glabrous.

Legs. Length of hind femur, tibia and basitarsus 5.2, 9.2 and 5.0 times their width, respectively; hind coxa smooth; hind femur with short and sparse setosity; outer side of apical third of middle tibia with a row of 4 pegs; 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.

Metasoma. First tergite slender shiny, rugulose near apex, slightly and roundly widened apically; length of first tergite 2.7 times its apical width; dorsal carinae of first tergite divergent and on three-fourths of tergite; second tergite 1.6 times as long as wide apically and with posteriorly diverging striae, apical third of second tergite with transverse furrow; anterior half of third tergite striate and apical half finely granulate; remainder of metasoma smooth, ovipositor sheath wide and ribbon-shaped, as long as fore wing.

Colour. Black; malar space, lower part of temple and face laterally narrowly ivory, clypeus, palpi and medial part of face pale yellow; antenna, legs and metasoma yellowish-brown, but tarsi paler than tibiae; wing membrane rather dark brown.

Male. Unknown.


Vein M+CU of hind wing 0.5-0.6 times as long as 1-M; length of first tergite 2.7-2.8 times its apical width; length of hind femur, tibia and basitarsus 5.2-5.3, 9.0-9.4 and 5.0-5.2 times their width; outer side of apical third of middle tibia with a row of 3-5 pegs; outer side of hind tibial apex with cluster of 67 pegs.


Oriental region. China (Guangdong).




This new species is very similar to B. antefurcalis  Watanabe, but differs in having the first tergite 2.7-2.8 times as long as its apical width; length of hind femur about 5.2-5.3 times as long as its width and area below face and clypeus ivory.
