Sweat Bee With Black And Metallic Green Banded

This afternoon I went hunting photography in the local forest, I found the sweat bee. From the shape of the head and face, I assumed it was the Nomia universitatis species. But what makes me doubt is the black and metallic green band on its abdomen, it looks like the blue banded bee (Amegilla cingulata). I've seen Nomia u. a few times, their abdomen has black and yellow bands. This is the first time I've seen the sweat bee with black and metallic green abdomen bands.
