An honest question:

Why exactly can L. bulla Benson 1836 be considered nomen nudum? Or any
name for that matter, I think Richard zander makes a good point about
where can you draw the line.

I agree with the intepretation of this particular name being
meaningless, but there must be a more objective parameter.
