Tegula yellow, pronotum laterally rusty. Legs yellow, middle coxa brown, hind coxa dark brown. Wings subhyaline, pterostigma brown and veins light brown.

Variable features of the females (29): Body 3-4 mm long. Antenna with 27-34, usually 30-32, antennomeres. Flagellomere 1.7-3 times as long as broad, length of flagellomeres in reverse proportion to number of flagellomeres. Head in dorsal view 1.75- 1.9 times as broad as long. Hind femur 2.9-3 times as long as broad medially. Pterostigma usually 2.85-2.9 times, rarely 3.1-3.3 times, as long as wide.

Description of the male (17): Similar to the female. Body 2.5-3(-3.2) mm long. Antenna as long as body and with 23-28(-35) antennomeres, flagellomeres 2.5-3 times as long as broad. Head in dorsal view 1.7-1.8(-1.9) times as broad as long, temple frequently less receded or rather rounded ( Fig. 349 ). Hind femur 3.3-3.7 times as long as broad medially. Pterostigma 2.8-3.3 times as long as wide. First tergite 1.2-1.4 times as long as broad behind, more sculptured than that of female and beyond pair of spiracles either parallel-sided ( Fig. 350 ) or slightly broadening (cf. Fig. 347 ). Body frequently with yellow or reddish yellow pattern.

H o s t: unknown.

R e m a r k s: Within the subgenus Glabrobracon the species B. subsinuatus is nearest to B. epitriptus MARSHALL viewing their elongate mesosoma, less broadening first tergite and length of ovipositor sheath; the two species differ from each other by a few features keyed:

1 (2) Second tergite less long, usually slightly (rarely 1.3 times) longer than third tergite ( Fig. 351 ). Head in dorsal view less transverse, 1.6-1.7 times as broad as long ( Fig. 352 ). Basal lobe of claw less large ( Fig. 353 ). Pterostigma issuing r usually proximally from its middle ( Fig. 354 ). Tergites 2-3 usually entirely black, sometimes laterally yellow, pale yellow or reddish yellow.: 2.5-3.5(-4.5) mm........ ................................................................................. B. (Gl.) epitriptus MARSHALL 1885

2 (1) Second tergite long, 1.3-1.4 times longer than third tergite ( Fig. 347 ). Head in dorsal view transverse, 1.8-1.9 times as broad as long ( Fig. 339 ). Basal lobe of claw relatively large ( Fig. 344 ). Pterostigma issuing r usually from its middle ( Fig. 345 ). Tergites 2-3 laterally reddish yellow, otherwise black.: (2.5-) 3-4 mm ..................... .............................................................................. B.

The species B. subsinuatus was frequently identified as B. discoideus WESMAEL , i.e. the two species were not clearly differentiated (cf. PAPP 2004: 182). The recent examination of the types of both species in question made possible their unambiguous distinction: 1 (2) Second tergite somewhat (1.1-1.2 times) longer than third tergite ( Fig. 355 ). Temple

in dorsal view rounded ( Fig. 356 ). Hind femur 3.6-3.8 times as long as broad ( Fig.

357). Claw somewhat more downcurved ( Fig. 358 ).: 2.5-3 mm ..............................

view rather receded ( Fig. 339 ). Hind femur 3-3.1 times as long as broad ( Fig. 343 .

Claw somewhat less downcurved ( Fig. 344 ).: 2.5-3.5 mm .......................................
