title: Taxonomic status and redescription of the genus Brasicystis Thatcher, 1979 (Digenea: Didymozoidae).
abstract: Brasicystis bennetti Thatcher, 1979 was first described from specimens obtained from the subcutaneous tissues of the mouth and operculum of Plagioscyion squamosissimus from the Amazon River in Brazil, however since 2008, Brasicystis has been considered a genus inquirendum. This study reviews some of the diagnostic characters from the original description of B. bennetti from the Amazon Delta, and redescribes the genus and species with a discussion of their taxonomic status. Ultrastructural and molecular approaches complement the data presented on this monotypic genus. The diagnosis of the tribe Didymozoini Monticelli, 1888 is amended to incorporate the genus Brasicystis, which is redescribed and revalidated here, with the proposal of an amended key.
