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

1 (2) Head in dorsal view (Fig. 61) transverse, 1.8-2 times as broad as long. First tergite 1.4-1.8 times as long as broad behind (Figs 67-69). Ovipositor sheath usually as long as hind tibia + basitarsus combined. $: 2-5 mm, o*: 1.8-4.5 mm B. (Gl.) obscurator NEES 2 (1) Head in dorsal view (Fig 71) less transverse, 1.6-1.7 times as broad as long. First tergite quadrate to subquadrate, i.e. as long as to slightly longer than broad behind (Figs 72, 73). Ovipositor sheath usually as long as hind tibia. Ç: 2-3.2 mm, S'- 2.3-3 mm B. (Gl.) pachyceri QUINTARET 2) The two forms considered here as two species, B. pachyceri and B. terebella (see also key couplets 32 [29] - 36 [35] p. 235), are very similar to each other; their specific distinction, on the basis of their original descriptions and of the few specimens of B. pachyceri at hand (B. terebella is a frequent species and, consequently, represented by a long series of specimens), are subtle and disputable. Besides the eidonomic-taxonomic study an extensive bionomical-ecological observations are needed to solve this problem. Figs 71-77.
