Thanks Lj, Bill, I use the name {cerana} very loosely, these are a small bee like Cerana. However these are just a small bred, treatment free bees, or just little mutts that resemble cerana.
I have simple guides for bees: Black/yellow I call Italian
Black I call Carniolan
Grey/black I call Caucasian
Small bee with 4 yellow bands I call cerana.
Yellow and brown, no black at all, I call Cordovans, queens are reddish head and chest.
I am not exactly a zoologist, very obvious.
Blessings
