Taxonomic position

Within the subgenus Osculobracon the species B. osculator is nearest to B. cingulator Szépligeti. Considering their long vein SR1 approaching to reaching tip of forewing, the two species differ by the following features:

1 (2) First tergite 1.3-1.4(-1.6) times as long as broad behind, third tergite one-third longer than second tergite ( Fig. 65I ). Temple in dorsal view rounded ( Fig. 65B ). Mesosoma in lateral view 1.4 times as long as high. Claw slightly more downcurved and its basal lobe more distinct ( Fig. 65F ). Legs brown with yellow(ish) pattern. Body black (nominate form). Head and mesosoma with more or less brownish to reddish yellow colour pattern, legs more or less yellow ( var. temporalis Telenga ). ♀: (1.5-) 2.2-3.5 mm .............................................................................. B. (Osc.) osculator Nees, 1811

2 (1) First tergite 1.8-2 times as long as broad behind, third tergite twice longer than second tergite ( Fig. 66A, D ). Temple in dorsal view receded ( Fig. 66 E-G). Mesosoma in lateral view 1.5-1.8 times as long as high. Claw less downcurved and its basal lobe less distinct ( Fig. 66H ). Legs yellow. ♀: (1.8-)2.4-3(-3.5) mm ................................................................... B. (Osc.) cingulator Szépligeti, 1901
