A Revision of the Genus Campichoeta Macquart (Diptera: Diastatidae)

Abstract

Examination of material of the genus Campichoeta Macq. (= Thryptocheta Rond.) from both the Old and the New Worlds, follawing clarification of the identities of most of the Palaearctic species by Basden and Collin (1958), revealed significant new information on the taxonomy of the genus. It showed that the common species in North America, heretofore called Thryptocheta micans Hendel (1911), is the same as Campichoeta griseola (Zett.) (1855) known from a single collection apparently made by Boheman in central Sweden about 1852. Also, it showed that an undescribed species occurs in southwestern United States.
