Yes there is a definition of
Neotheropoda that includes Coelophysis & it was
defined but it outlawed by Phylocode because it didnt
follow the original usage.
As noted by Mickey, PhyloCode is not yet in effect and it only governs clade
names published on January 1, 200n or afterwards. So there's no reason why
it can't yet be used, however, I would prefer to use the Neotheropoda sensu
Sereno, 1999.
