Abstract

With more than 200 species worldwide, Hydrellia Robineau-Desvoidy is the largest genus of the family Ephydridae (Diptera). However, knowledge of this genus is much reduced in Brazil and throughout the Neotropical Region, where only 8 species are known, including one from Brazil (H. xanthocera Cresson). The objective of this study is to review the species of Hydrellia from Brazil, with an emphasis on the faunas of Paraná and Rio de Janeiro states. Six new species are described: H. bocaiuvensis sp. nov. (Brazil, Paraná, Bocaiúva do Sul, 25°14.9'S, 49°8.9'W, 890 m), H. longiseta sp. nov. (Brazil, Paraná, Parque Iguaçú, 25°33.4'S, 49°13.6'W, 880 m),H. vilelai sp. nov. (Brazil, Paraná, Bocaiúva do Sul, 25°16.6'S, 48°58.5'W, 770 m), H. simplex sp. nov. (Brazil, Paraná, Parque Iguaçú, 25°33.4'S, 49°13.6'W, 880 m) e H. schneiderae sp. nov. (Brazil, Paraná, Parque Iguaçú (25°33.4'S, 49°13.6'W, 880 m), H. similis sp. nov. (Brazil, Paraná, Bocaiúva do Sul, 25°14.9'S, 49°8.9'W, 890 m). Seven new registers are recorded: H. agitator (Pará), H. apalachee (Paraná and Rio de Janeiro), H. calverti (Amazonas and Paraná), H. cavator (Rio de Janeiro), H. tibialis (Amazonas, Paraná and Rio de Janeiro), H. vulgaris (Paraná, São Paulo, Santa Catarina and Rio de Janeiro), H. wirthi (Pará, Paraná and Santa Catarina). Together with H. xanthocera, Hydrellia now includes 14 species from Brazil.
