Manuelia
Manuelia is a genus of bees in the subfamily Xylocopinae, the only genus in the tribe Manuelini. There are three species.
This tribe is relictual. Today it is limited to Chile and Argentina.
These are small, slender bees measuring up to 8.5 millimeters long. They may be metallic blue or matte black, sometimes with reddish parts on the abdomen. Because Manuelia species are so distinct from each other, the genus is divided into two subgenera.
