 Thank you Paul. Is it B. vallata because the hind tibia is black in the distal extremity?

 To be more clear in my statement: all tibiae are darkened for a considerable distance appically in B. vallata (at least one third, usually even more). In clavipes it is just the extreme tip that is darkened.
