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.

The Anthomyiidae (Diptera) are known from about 1,100 species mostly occurring in temperate to arctic areas in the northern hemisphere. Few species have been reported from the Australasian and Oceanian Regions. New Caledonia, located in Melanesia, in the southwest Pacific Ocean, is well known for its high diversity, endemism and large number of unknown species. Specimens of Anthomyia Meigen from New Caledonia were found at the Muséum national d'Histoire naturelle (Paris) collection. The species was identified as A. medialis Colless, and represents the first record of Anthomyiidae from the island. A key to the Anthomyia species occurring in these regions is presented, as well as illustrations of the male terminalia of A. medialis.
São conhecidas cerca de 1.100 espécies de Anthomyiidae (Diptera) ocorrendo principalmente em áreas temperadas e árticas no hemisfério norte. Poucas espécies têm sido relatadas nas regiões da Australásia e Oceania. Nova Caledônia, localizada na Melanésia, no sudoeste do Oceano Pacífico, é bem conhecida por sua alta diversidade, endemismo e grande número de espécies desconhecidas. Espécimes de Anthomyia Meigen da Nova Caledônia foram encontrados na coleção do "Muséum national d'Histoire naturelle" (Paris). A espécie foi identificada como A. medialis Colless, sendo este o primeiro registro de Anthomyiidae da ilha. Chave de identificação para as espécies de Anthomyia ocorrentes nessas regiões é apresentada, bem como ilustrações da terminália masculina de A. medialis.
