in addition to what Gary wrote (I agree entirely with it): you also asked
indirectly also about the correct authorship of the name:
> the correct name should be Genus species XY in ABC
No, not necessarily. The correct name and authorship must be derived from
the publication in which the name was made available (ABC's paper), not
from the publication where the name was mentioned as a nomen nudum (XY's
So in your case it would be correct as Genus species ABC, if no other
authorship was indicated in ABC's paper.
If another authorship was indicated in ABC's paper, then you must pay
attention and follow strictly the rules of Art. 50.1 and 50.1.1. These
rules are not easy to understand. Basically you can have two cases.
I assume for a first case that A, B, C, X and Y stand for 5 different
If Genus species was presented in ABC's paper without authorship, then ABC
gets the authorship by default.
If X & Y was indicated as the authorship in ABC's paper (in a form Genus
species X & Y n. sp.), then Art. 50.1.1 applies: you have to look for who
was expressly indicated as having been responsible for the description. If
ABC said that X and Y were ALONE responsible for the description, then X &
Y get the authorship, and you can cite it as Genus species XY in ABC. Very
important is "alone".
If there is no such indication in ABC's paper, or if the context suggests
that X and Y were not alone responsible for the description (because ABC
gave some additional information that contributed to the description, no
matter how significant or important this contribution was), then ABC get
the authorship alone, and X & Y are not included to the authorship.
If X and Y are identical with B and C (second case), and the name is cited
in ABC's paper in a form Genus species B & C n. sp., then Art. 50.1
applies and it is not necessary to look for who was responsible for the
description. This is because B and C were co-authors of ABC's work. In
such a case the new name is cited as Genus species BC in ABC.
Very complicate rules, but, well. I hope this helps in this detail of your
