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

light brownish, second and third coxae blackish brown. Tegula yellow or brownish yellow. Hind tibia apically and entire hind tarsus brownish fumous. Wings faintly fumous (or subfumous), pterostigma and veins opaque brownish. Description of the female paratypes (11 $)- Similar to the female holotype. Body 2.8-3.6 mm long (2.8: 1 Ç, 3: 1 Ç, 3.1: 1 $, 3.2: 2 Ç, 3.3: 2 Ç, 3.4: 2 ?, 3.6: 1 $). Antenna with 25-29 antennomeres (25: 1 $, 27: 1 Ç, 28: 4 $, 29: 4 $; 1 $ with damaged antenna). Head in dorsal view 1.8-1.9 times as broad as long. Hind femur 3.6-3.8 times as long as broad somewhat distally. 1-M 1.7-1.9 times as long as m-cu, 1-SR-M 1.2-1.3 times as long as 1-M. First tergite 1.3-1.6 times as long as broad behind (1.3: 2 $, 1.4: 5 $, 1.5: 3 $, 1.6: 1 $)., beyond pair of spiracles sides of tergite parallel or just subparallel. Ovipositor sheath usually as long as hind tibia + tarsus (9 $), exceptionally somewhat longer (2 $). Tergites fully black (2 Ç). Description of the male paratype (1 <$) - Similar to the female. Body 2.5 mm long. Antenna somewhat longer than body and with 26 antennomeres. First flagellomere 2.1 times and penultimate flagellomere twice as long as broad. Head in dorsal view 1.8 times as broad as long. Notaulix less distinct. Hind femur 3.6 times as long as broad somewhat distally. First tergite (Fig. 8) 1.35 times as long as broad behind. Tergites less transverse, second tergite 2.2 times as broad behind as long laterally. Suture between tergites 2-3 straight (an exception?). Second tergite antero-medially longitudinally rugulose. Second tergite yellow, medially blackish brown. Host- Byctiscus betulae LINNAEUS (Col. Attelabidae), braconid emerged from the leaf-roll of Populus tremula LINNAEUS made by the attelabid beetle. Distribution - Hungary and Bulgaria. The new species, Bracon (Glabrobracon) admotus, is nearest to B. (Gl.) colpophorus WESMAEL, their distinction is presented in the key couplets 43 (46)45(44), p. 236. Also near to the new species B. (Gl.) kopelkei considering their common features as black body, yellow legs and tegula, strongly rounded temple, distinctly bisinuate suture between tergites 2-3 ($), long second submarginal cell and long ovipositor sheath; the two species are distinguished by the features keyed: 1 (2) Second tergite polished ($) or antero-medially rugulose (cT). First tergite 1.3-1.6 times, usually 1.4 times, as long as broad behind, beyond pair of spiracles sides of tergite parallel to just subparallel; tergites 2-3 equal in length (Fig. 7). Trochantellus yellow. Ç: 2.8-3.6 mm, 2.5 mm B. (Gl.) admotus sp. n. 2(1) Second tergite antero-medially rugose to rugulose, first tergite 1.1-1.2 times as long as broad behind, beyond pair of spiracles sides of tergite more or less diverging; second tergite slightly longer than third tergite (Fig. 44). Trochantellus brown to blackish. Ç: 3.3-3.5 mm B. (Gl. ) kopelkei sp. n.
