Papp, J.: First synopsis of the species of obscurator species-group, genus Bracon, subgenus Glabrobracon (Hymenoptera: Braconidae, Braconinae)

longer than third tergite, second tergite medially (Fig. 59) or nearly entirely and rather longitudinally rugulose, further tergites polished. Suture between tergites 2-3 bisinuatc (Fig. 59). Ovipositor sheath as long as hind tibia + tarsomeres 1-2 combined. - Body black. Mandible yellow, palpi brownish. Tegula brownish yellow to yellow. Hind narrow rim of second tergite and sternites 1-2 entirely yellowish. Legs yellow, coxac-trochanters dark brown to black, femora proximally more or less brown to blackish, tarsi faintly brownish. Specific features of the male (1 S, male new) - Similar to the female. Body 3.3 mm long. Antenna somewhat longer than body and with 31 antennomeres. Penultimate flagellomere 1.45 times as long as broad. Head 1.8 times as broad as long. Oral opening somewhat larger, its horizontal diameter 1.4 times as long as shortest distance between opening and eye. Hind femur 3.6 times as long as broad medially. First tergite 1.3 times as long as broad behind and with diverging sides. Second tergite one-fifth longer than third tergite. Tergites dark brown. Dark pattern of legs more extended. Host - Mompha nodicolella FUCHS (Lep. Momphidae). Distribution - England, Scotland, Denmark. Taxonomic position - Within the subgenus Glabrobracon the species Bracon momphae stands nearest to B. kopelkei sp. n., their distinction see in the key-couplets 11 ( 14) - 13 ( 12), p. 232. The species B. instabilis MARSHALL is also allied to B. momphae, the two species are distingushed under the former species, p. 233.
