First discal cell fairly high, 1-M 1.8 times as long as m-cu and nearly parallel with each other; 1-SR-M 1.4 times length of 1-M ( Fig. 346 View Figs 339-350 ).

First tergite ( Fig. 347 View Figs 339-350 ) 1.3 times as long as broad behind, beyond pair of spiracles weakly broadening, margin of scutum crenulate, scutum posteriorly striate. Second tergite 2.3 times wider behind than long laterally and distinctly, i.e. nearly 1.4 times, longer than third tergite medially; fore half of second tergite striate, otherwise together with further tergites polished ( Fig. 347 View Figs 339-350 ). Hypopygium small and pointed, ovipositor sheath as long as hind tibia + tarsomeres 1-2 combined ( Fig. 348 View Figs 339-350 ).

Body black with little light pattern. Scape reddish yellow, pedicel and flagellum brown. Inner margin of eye reddish yellow, vertex at eye rusty. Oral organs yellow, palpi pale yellow. 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.

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 View Figs 351-358 ). Head in dorsal view less transverse, 1.6-1.7 times as broad as long ( Fig. 352 View Figs 351-358 ). Basal lobe of claw less large ( Fig. 353 View Figs 351-358 ). Pterostigma issuing r usually proximally from its middle ( Fig. 354 View Figs 351-358 ). 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 View Figs 339-350 ). Head in dorsal view transverse, 1.8-1.9 times as broad as long ( Fig. 339 View Figs 339-350 ). Basal lobe of claw relatively large ( Fig. 344 View Figs 339-350 ). Pterostigma issuing r usually from its middle ( Fig. 345 View Figs 339-350 ). 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 View Figs 351-358 ). Temple

in dorsal view rounded ( Fig. 356 View Figs 351-358 ). Hind femur 3.6-3.8 times as long as broad ( Fig. View Figs 351-358

357). Claw somewhat more downcurved ( Fig. 358 View Figs 351-358 ).: 2.5-3 mm ..............................

view rather receded ( Fig. 339 View Figs 339-350 ). Hind femur 3-3.1 times as long as broad ( Fig. 343 View Figs 339-350 .
