I still say that if you were to give every single species a unique praenomen,
the second part of the name would become useless, and there would be no good
reason to keep it apart from sentimental attachment.

(lower case _mongoliensis_ would be preferrable, I think.)

But, you see, the citation *is* part of the (full) name!

This is, I think, the major problem with this system, but it's not
insurmountable. Unless we want to rename one of them, it would merely require
additional notation as part of the full name. Perhaps something like:
_mongoliensis_ Osborn 1924 (typus _Velociraptor_)
_mongoliensis_ Osborn 1924 (typus _Saurornithoides_)

Thereafter in the text they could be abbreviated as _S. mongoliensis_ and _V.

If they had not been type species you could use "ref." instead of "typus".
Imaginary example (since I can't think of a real one at the moment):
_virginianus_ Author 1900 (ref. _Alphacladus_)
_virginianus_ Author 1900 (ref. _Betacladus_)

And if the second one had been subsequently referred elsewhere (say,
_Gammacladus_), that would be mentioned, and it could then be abbreviated as
_G. virginianus_.

Just an idea; I'd like to hear of others.
