Anthodioctes calcaratus. A small bee from La Cruz, Costa Rica. Collected by Tim Mcmahon on one of his several bee trips to that country. I can't scrounge up much about these hole nesters from Central and South America, but likely there are Brazilian papers out on the topic.

Here is a natural history account of a Brazilian species in this genus:
