Three new genera of Protandrenini bees from South America (Hymenoptera, Apidae, Andreninae)

Three new genera of Protandrenini bees from South America are described. Luisanthrena new genus is proposed to include L. ruzae, new species (from Ecuador) and L. vargasllosai (Gonzalez & Alvarado, 2019), new combination (from Peru). The new genus Cisanthrena includes only the unusual species Cisanthrena perforata n. sp. from forested areas of the Andes in Peru. In addition, Austellurgus new genus is proposed to accommodate A. avulsus (Ramos & Melo, 2006), new combination (southeastern Brazil).
