[Taxacom] Clarification of Code's Article. 13.1.2

Basically the paper being referred to has to have a statement in text which
claims to differentiate, ie separate, the species being discussed. Its
basically a claim that this character works, it does not in fact have to be
correct about this. So no matter how bad the description being cited is, if
it claims to separate the species its a valid description. This original
description I assume has a type, hence the differentiation is attached to
that type, extra specimens examined no matter how many species are also not
grounds to invalidate it. From what your saying it sounds like a valid
name, meeting the criteria of 13.1.2.

Cheers, Scott
