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 Parana and Rio de Janeiro states. Six new species are described: H. bocaiuvensis sp. nov. (Brazil, Parana, Bocai va do Sul, 25 degrees 14.9' S, 49 degrees 8.9' W, 890 m), H. longiseta sp. nov. (Brazil, Parana, Parque Iguau, 25 degrees 33.4' S, 49 degrees 13.6' W, 880 m), H. vilelai sp. nov. (Brazil, Parana, Bocai va do Sul, 25 degrees 16.6' S, 48 degrees 58.5' W, 770 m), H. simplex sp. nov. (Brazil, Parana, Parque Iguau, 25 degrees 33.4' S, 49 degrees 13.6' W, 880 m) e H. schneiderae sp. nov. (Brazil, Parana, Parque Iguau (25 degrees 33.4' S, 49 degrees 13.6' W, 880 m), H. similis sp. nov. (Brazil, Parana, Bocai va do Sul, 25 degrees 14.9' S, 49 degrees 8.9' W, 890 m). Seven new registers are recorded: H. agitator (Para), H. apalachee (Parana and Rio de Janeiro), H. calverti (Amazonas and Parana), H. cavator (Rio de Janeiro), H. tibialis (Amazonas, Parana and Rio de Janeiro), H. vulgaris (Parana, Sao Paulo, Santa Catarina and Rio de Janeiro), H. wirthi (Para, Parana and Santa Catarina). Together with H. xanthocera, Hydrellia now includes 14 species from Brazil.
