Hind femur slender.......................................... 2 - Propodeum without apical carina, petiolar area not limited. Hind femur variable.................................... 3 2 Flagellum with white ring. Hind femur 5.0 × as long as wide............................... B. nitidus (Hao & Sheng) - Flagellum without white ring. Hind femur 6.0 × as long as wide.................... B. unicarinatus (Uchida & Momoi) 3 Scutellum and postscutellum yellow ( Fig. 12 ). All tergites with distinct yellow stripes apically ( Figs 8, 9 )..................................................................................................
