The name shouldn't have to change, even if its later moved to another group.  
(for example, Megalonyx didn't get renamed when we discovered it was a sloth 
and not a lion)


if, by some hypothetical, the original specimen of Mei long gets reanalyzed as 
a member of genus Troodon, currently it would become Troodon long...but if we 
get rid of species, its just Troodon?


(I just had that link David shared, and now its lost; gah)


but that first example gets into this aspect:

Apologies then; I had thought the discussion had shifted to include branches 
above the Genus level as well as the binomials.
