Descrition.

Female. Fore wing length 2.5-3.4 mm. Width of head (dorsal view) 1.8-2.0 × its median length. Transverse diameter of eye (dorsal view) 1.7-2.1 × longer than temple. OOL 2.3-2.4 × Od; POL 1.2-1.4 × Od; OOL 1.7-1.9 × POL. Longitudinal diameter of eye (lateral view) 1.4-1.5 × its transverse diameter; hind margins of eye and temple broadened downwards or subparallel. Face width about 1.4 × combined height of face and clypeus. Longitudinal diameter of eye 2.6-3.0 × longer than malar space (anterior view). Malar suture deep, smooth. Width of hypoclypeal depression 1.1-1.2 × distance from depression to eye. Antenna 1.1-1.2 × longer than fore wing, with 29-34 antennomeres. First, middle and penultimate flagellomeres 2.2-2.3 ×, 2.0-2.1 ×, and 2.0-2.2 × longer than wide, respectively. Mesosoma 1.5-1.6 × longer than its maximum height. Mesoscutum setose only on notaulic area. Notauli impressed anteriorly, shallow posteriorly. Mesepimeral and metapleural sulci smooth. Propodeum without medio-longitudinal keel. Fore wing vein r arising from basal 0.4 × of pterostigma; vein 1-R1 about 1.3 × longer than pterostigma; marginal cell about 5.2 × longer than distance from its apex to apex of wing; vein 3-SR 2.3-2.5 × vein r, about 0.6 × vein SR1, 1.6-1.7 × vein 2-SR. Hind femur 3.8-4.3 × longer than wide. Hind tibia with 1-2 thick setae subapically. Fifth segment of hind tarsus 0.35-0.40 × as long as hind basitarsus, 0.60-0.65 × as long as second segment. Claws with large, protruding and blunt basal lobes. First metasomal tergite without dorsal and dorsolateral carinae, its median length 1.1-1.3 × its apical width. Second tergite with weak triangle median area and with very shallow s-shaped smooth dorsolateral impressions not bordered by carinae; medially 0.93-0.97 × as long as third tergite; its basal width 1.7-1.8 × its median length. Second metasomal suture deep, curved and smooth or weakly crenulate. Anterolateral margin of second metasomal tergite at most shortly desclerotised, apical margins of third to sixth tergites widely desclerotised. Ovipositor sheath about 0.65 × as long as hind tibia, about 0.2 × as long as fore wing. Apex of ovipositor with weak nodus and ventral serration. Head and mesosoma entirely smooth; first tergite weakly rugulose laterally and posteriorly, second and sometimes also third tergite weakly rugulose, but smooth on sides, fourth-fifth tergites hardly granulate to smooth. Body black or brown, legs and palps yellow, apex of hind tibia and hind tarsus brown; wing membrane weakly darkened, pterostigma and veins brown.

Diagnosis.

Within the subgenus Bracon Osculobracon Papp, Bracon cingillus Tobias is most similar to B. subcingillus Tobias, 2000 because of the crenulated furrow of the first metasomal tergite, more or less complete absence of desclerotised areas in anterolateral margins of the second metasomal tergite, and development of sculpture on two basal tergites (Fig. 90 ). The differences between two species are listed below.

1	Median length of first metasomal tergite (measured from spiracle) 0.8-1.0 × its apical width (Fig. 90 ). Claws with large acutely protruding basal lobe. Mesosoma 1.5-1.6 × longer than its maximum height	Bracon (Osculobracon) cingillus Tobias
-	Median length of first metasomal tergite (measured from spiracle) 1.2 × its apical width. Claws with small weakly pointed basal lobe. Mesosoma 1.4 × longer than its maximum height	Bracon (O.) subcingillus Tobias
