Note: B. caliginosus is easily overlooked due to similarities with B. vosnesenskii. females can be differentiated from B. vosnesenskii based on the slightly but dictinctly loner malar area, and the extensive pale hairs on S4. Males can be identified gased on the same malar features, and the wider, expanded penis valves (LR Best, personal communication).
