Abstract

The species of the New World syrphid genus, Quichuana Knab, 1913 (Diptera: Syrphidae: Eristalini), are revised and the genus is re-diagnosed. Twenty-four new species are described, bringing the total number considered valid to 48. New species were mostly reared from Bolivia, Brazil, Costa Rica, El Salvador, Mexico, Peru, Trinidad, and Venezuela. The male of Quichuana picadoi is described for the first time. Quichuana championi is proposed as a synonym of Quichuana cincta, Quichuana aurata as a synonym of Quichuana angustiventris, and Quichuana sepiapennis as a synonym of Quichuana calathea. Quichuana inca var. brevicera is raised to specific status. Lectotypes are designated for Helophilus auratus, Quichuana bezzii, Quichuana fasciata, and Quichuana parisii. A species-level identification key for both males and females is provided. Male genitalia of 18 species are illustrated.
