It has officially changed from Elaphe to Pantherophis, but many hobbyist still use Elaphe, kind of how they still call Florida kings "Brooksi phase" florida kings when they are actually the nominate subspecies and what used to be Florida kings are now Peninsular Integrade Kings. Names are really fun!!!!
Oh and to make things more confusing, Black rats don't exist anymore either....they're now called Eastern Rat snakes. Just a little bit more confusion for you.
