Abstract
The identity of three species of Chrysotus Meigen (Diptera: Dolichopodidae) described by Millard Carr Van Duzee is clarified. Chrysotus brasiliensis Van Duzee (Brazil: Mato Grosso) is transferred to the genus Micromorphus Mik; C. parvipalpus Van Duzee (Brazil: Amazonas, Maranhão and Pernambuco) is redescribed and assumed to be closely related to C. antillensis Runyon (West Indies) and C. duzeei sp. nov. (Brazil: Roraima and Mato Grosso do Sul); and C. setosus Van Duzee (=C. neotropicus Dyte) is regarded as a junior-synonym of C. hirsutus Aldrich (Lesser Antilles, Dominica, Costa Rica, Peru, and newly recorded from Brazil: Pernambuco and Alagoas). In addition, C. brevitibia Van Duzee, previously known from Puerto Rico, Dominica and Argentina, is newly recorded from Brazil (Mato Grosso do Sul).
