This is a large group of mostly small, almost hairless bees which, except for parasitic species, make their nests in hollow, pithy or rotten stems and sometimes in vines. While there are about a dozen genera of these bees present in the Old World including the cleptoparasitic Eucondylops, Inquilina and Nasutapis, only the nearly worldwide genus Ceratina and the endemic Chilean genus Manuelia are present in the New World. ~Pithitis smaragdula (Fabr.) was intentionally introduced into the United States from Ludhiana, India on April 10, 1969 at Davis, California as a potentially important pollinator of economically useful plants, especially legumes and cucurbits (Daly, Bohart and Thorp, 1971. Jour. Econ. Ent. 64: 1145-1150). The introduction apparently was unsuccessful since no recoveries of this species have been reported.
