Papp, J.: First synopsis of the species of obscurator species-group, genus Bracon, subgenus Glabrobracon (Hymenoptera: Braconidae, Braconinae)
Hosts - Hoplocampa minuta (CHRIST) (Hym. Tenthredinidae); Coleophora sp. (Lep. Coleophoridae); Bruchidius villosus FABRICIUS, Bruchus pubescens GERMAR, B. spartii ERICHSON (Col. Bmchidae); Apion genistae KlRBY, Exapion difficile (HERBST) (Col. Brentidae, Apioninae); Oxystoma craccae LINNAEUS (Col. Curculionidae). - Remark: The bruchid, apionine and curculionid hosts are in need of confirmation. Distribution - England, Belgium, The Netherlands, France, Germany, Poland, Austria, Hungary, Romania, Italy and former Yugoslavia. Taxonomic position - Within the subgenus Glabrobracon the species Bracon colpophorus is nearest to B. admotus sp. n., their distinction is presented in the key-couplets 43 (46) - 45 (44), p. 236. Bracon (Glabrobracon) instabilis MARSHALL, Co* (Figs 29-37) Bracon instabilis MARSHALL, 1897: in E. ANDRÉ (ed.): Spec. Hym. Eur. Alg. 5: 70 Co*. Habrobracon instabilis (MARSHALL): SHENEFELT 1978: 1607 (literature up to 1953). Bracon (Glabrobracon) instabilis: PAPP 1997: 126 (new taxonomic position, designation of female lectotype, redescripton). Specific features of the females (5 $ ) - Body 2.2-3.5 mm long. Antenna somewhat shorter than to as long as body and with (23-)28-30 antennomeres. Penultimate flagellomere 1.4—1.6(— 2) times as long as broad. Head in dorsal view (Fig. 29) 1.8-1.9 times as broad as long, eye clearly one-third to twice as long as temple, temple fairly receded. Horizontal diameter of oral opening one-fifth longer than shortest distance between opening and eye. Head polished, face more or less finely granulate. Propodeum polished. Hind femur (3-)3.5-4 times as long as broad medially and nearly evenly broad (Fig. 30). Basal lobe of claw somewhat pointed (Fig. 31). - Pterostigma (Figs 32-33) (2.2-)2.8-3.3 times as long as wide and issuing r slightly proximally from its middle. Second submarginal cell short, 3-SR somewhat longer than 2-SR, 4-SR reaching tip of wing. First discal cell relatively long, I-2CU1 clearly longer than 1-M (Fig. 34, see arrows). - First tergite (Fig. 35) 1.2-1.4 times as long as broad behind, beyond pair of spiracles with parallel to somewhat diverging sides. Margin of scutum finely crenulate and hind end of first tergite rugose-rugulose. Tergites 2-3 equal in length, second tergite 2.8-3.4 times as broad behind as long and anteriorly almost entirely and rather longitudinally rugose-rugulose; further tergites polished. Suture between tergites 2-3 bisinuate (Fig. 35) to almost straight, subcrenulate. Ovipositor sheath as long as hind tibia or somewhat shorter. Body black, metasoma frequently brownish black. Palpi yellow or brownish yellow. Legs dark brown to black(ish) and either femora apically and tibiae basally yellow, brownish yellow or fore femur + tibia and tibiae 2-3 basally yellow with variable extent. Specific features of the males (3 S) - Similar to the female. Body 2.2-3 mm long. Antenna as long as body and with 26-27 antennomeres. Temple in dorsal view a bit less receded (Fig. 36). Penultimate flagellomere 1.8 times as long as broad. Pterostigma (Fig. 37) 2.4 times as long as wide. Second tergite sometimes smooth to almost smooth.
