This is not the case of a species split, but a genus split that merely assigned an existing species to a different genus.The genus Mecistops was split from Crocodylus recently; hence, all slender-snouted crocodiles (formerly considered Crocodylus cataphractus) are Mecistops cataphractus.
Yes but M. cataphractus has also been split into two species, one of which has yet to be described.
