The term "race" when applied to bees is no longer used. We prefer to call them subspecies, or types. Color is simply not a reliable indicator of anything in bees. Just like with Labrador retrievers, they come in black, brown, or yellow. The color means absolutely nothing, except -- that's what color they are.
In the US the terms Italian, Carniolan, etc. have long since lost their significance. Only DNA testing will tell you the genetic background of the bees. I have a breeder carrying an A. m. mellifera genetic marker. But she and most of her bees look like regular Italian types.
More important is: are they hygienic, are they good producers, are they vicious? These are the things that matter.
