Redescription of the Neotropical species Trichodischia sororBigot, 1885 (Diptera: Tachinidae), with a new generic synonymy

Alvarez-Garcia, Deivys MSantis, Marcelo Domingos de

Trichodischia Bigot, 1885 is a Neotropical genus with a confusing taxonomic history. This was initially composed of two species: T. caerulea Bigot, 1885 and T. soror Bigot, 1885. Later, the genus Trichoraea Cortés, 1974 was erected for T. caerulea.When reviewing the taxonomic history of both species, we discovered that both genera have been considered synonymous based on erroneous information and without a formal synonymy being proposed. Herein, we redescribed T. soror, provide images of adults and describe the male terminalia for the first time. In addition, by examining the type material, we propose Trichoraea as a junior synonym of Trichodischia,syn. nov., confirm T. caeruleacomb. rest. and T. soror as valid species and provide some comments about the taxonomy and host record of the genus.(AU)
