Taxonomic revision of the Neotropical genus Ormiophasia Townsend, 1919 (Diptera: Tachinidae), with the description of eight new species

Abstract

The Neotropical genus Ormiophasia Townsend, 1919 is revised. Of the nine nominal species included in the genus prior to this revision, eight are interpreted as valid, with one new synonymy: Ormiophasia travassosi Tavares, 1964 = Ormiophasia inflata (Séguy, 1927b), syn. nov. Eight new species are described: Ormiophasia guimaraesi sp. nov., Ormiophasia seguyi sp. nov., Ormiophasia crassivena sp. nov., Ormiophasia manguinhos sp. nov., Ormiophasia tavaresi sp. nov., Ormiophasia chapulini sp. nov., Ormiophasia buoculus sp. nov. and Ormiophasia townsendi sp. nov. The distribution of Ormiophasia is extended from northern Argentina to Southeast Mexico. A key to species and detailed descriptions, and illustrations, of adults of both sexes and male terminalia, are provided.
