Revision of the Neotropical genus Cheiromyia Dyte (Diptera: Dolichopodidae)

Abstract

The Neotropical dolichopodine genus Cheiromyia is revised. The limits of the genus are redefined to include only those species with one or more elongate projections on the male postpedicel. Cheiromyia maculipennis (Van Duzee) is transferred to Paraclius Loew comb. nov. Cheiromyia is now known from Costa Rica south to Bolivia and the Brazilian Atlantic Forest, and includes the following five species: Cheiromyia bicornis Brooks sp. nov., C. brevitarsis Brooks sp. nov., C. laselva Brooks sp. nov., C. palmaticornis (Parent) and C. pennaticornis (Parent). A key to males is provided, as well as some remarks on related species of Paraclius.
