Perdita (Epimacrotera) williamsi Timberlake 1962

Perdita (Epimacrotera) williamsi Timberlake, 1962 Endemic [Holotype: CASC; ♀ 16.09 km east of Bahia San Quintin, Baja California, Mexico; 10 September 1955] Perdita williamsi has few occurrences widely distributed in the BCP, meaning it is widespread but likely locally rare. It has been collected in the Succulent Coastal Matorral in the CFP in BC and in the Gulf Coast in La Paz, BCS (Timberlake 1962). We reviewed six specimens at CASC including the allotype (♂), and one paratype collected 10 mi. E. of Bahia San Quintin, BC, and two paratypes (♀) collected in La Paz, BCS. See fig. 38.
