Sugarbag Bee

Small bee. It is stingless and an Australian native bee. Size is about 6-7mm. I am not convinced that many people can identify this bee and I doubt that mine is correct. The taxon is confused and different ones are used by big biodiversity databases. I might rename and reclassify some of the individuals that I document. I can see a yellow collar in most of them to a certain degree, grey chest, hairy back and shiny abdomen.
