Abstract

Bees of the genus Protosmia subgenus Nanosmia are not well known.  Three new species are described and figured for both sexes: Protosmia (Nanosmia) hamulifera Griswold, new species, from the Arabian Peninsula, P. (N.) schwarzi Griswold, new species, from Morocco and Tunisia, and P. (N.) trifida Griswold, new species, from Turkey.  An updated diagnosis and new distributional records are provided for the recently described P. (N.) montana Müller.  The species is recorded for the first time from Turkey and Tadjikistan.
