21 (22) Second tergite antero-laterally, further tergite transversely and partly desclerotized. In dorsal view temple somewhat receded to strongly rounded. Species of oscillator-group: B. (Gl.) oscillator NEES, 1812; B. (Gl.) cingulator SZÉPLIGETI, 1901). 22 (21)Tergites entirely sclerotized. 23 (26)Head in dorsal view (Figs 78, 87) transverse. 1.75-1.9 times as broad as long, temple rather receded. Second submarginal cell relatively narrow (Figs. 80, 90,91,93). 24 (25)Second submarginal cell small and somewhat narrow: 3-SR hardly longer than 2-SR (minute variation feasible, Fig. 80). Temple in dorsal view rounded (Fig. 78). Claw relatively more curved (Fig. 79). $c?: (2.2-)2.6-2.9 mm B. (Gl.) parvicornis THOMSON 25 (24)Second submarginal cell usual in size and narrow: 3-SR longer than 2-SR (Figs 90, 93). Temple in dorsal view rather rounded (Fig. 87). Claw relatively less curved (Fig. 89). Body black, first tergite brownish yellowish (melanic form). Cc^: 2-3 mm - See also couplets 2(3) and 40 (39) B. (Gl.) pauris BEYARSLAN 26 (23)Head in dorsal view (Fig. 52) less transverse, 1.6-1.7 times as broad as long, temple rounded. Second submarginal cell usual in its width, i. e. not narrow (Fig. 53). Tergites 2-3 equal in length (Fig. 54). Wings subhyaline to weakly fumous. Co 71 : 1.8-2.2 mm - See also couplet 8(9) B. (Gl.) marshalli SZÉPLIGETI 27 (20)Marginal cell of fore wing not shortening, i.e. 4-SR reaching tip of wing (Figs 4, 23, 49, 65, 76, 80, 83). 28 (37)Head in dorsal view less transverse, 1.6-1.7 times as broad as long (Figs 14, 45,71,74) 29 (32)First tergite long, 1.4-1.6 times as long as broad behind, rim laterally from scutum usually narrow (Figs 50, 51). Ovipositor sheath long, at least as long as meta- and mesosoma combined. Antenna with 17-26 antennomers.
