Synonyms and other taxonomic changes
Formerly included in Psaenythia but that genus, as currently recognized, is South American.
Several other genera were included in Protandrena by Michener (2000, 2007) but this has not been generally accepted by panurgine specialists as the resulting group is heterogeneous and surely not monophyletic.
