Well, it depends which group you take. Polyphyly usually arises when too
many species arr put under one genus, I guess that my definition of Erosaria
assembles a polyphyletic group, but in subgenera you usually have only two
or three species, and polyphyly is at very low rank then.

Sincerely
Felix
