Thickness of the band can be a useful key in differentiating the two similar species, B. asahinai and B. vaga. B. vaga has thicker bands and the bands have relatively smooth edges compare to "squiggly" bands on asahinai.

Thank you!
I just looked up pictures of B. asahinai and B. vaga and compared the bands, and you're totally right! Thanks Alan! I'm continuously learning so this will help me in the future! :-)

Glad I could help :)
On a side note, some asahinai can develop relatively straight looking bands. In that case, you can simply look at the way the bands are aligned. B. asahinai has bands that are relatively parallel to each other, whereas B. vaga has bands that points outward.
