In male genitalia of B. apatani (Fig. 6), the uncus is shorter and more dilated subapically; the valva is shorter, broader and almost rectangular and the vesica with two diverticula, each with a cluster of strong cornuti apically, whereas in the male genitalia of B. phaeoxanthia (Fig. 7), the uncus is longer and subapically less dilated, the valva is long and narrower at apex and the vesica bears a single cluster of 1–3 cornuti apically.
