Abstract

Two new species of New World halictine bees (Halictidae: Halictinae) are described and figured with extreme forms of female macrocephalism. Lasioglossum (Evylaeus) xitle sp. nov. (Halictini: Gastrohalictina) from Cráter del Xitle in Mexico City, Mexico and Augochlora (Oxystoglossella) empusa sp. nov. (Augochlorini: Augochlorina) from Madre de Dios, Peru are remarkable for not only their greatly enlarged heads and monstrously developed mandibles, but also for their pronotal modifications (both species), propodeal lamellae (A. empusa), and genal (L. xitle) and hypostomal (A. empusa) protrusions.
