The family Aeglidae comprises the genus Aegla with recent species and the genus Haumuriaegla with the fossil species H. glaessneri Feldmann, 1984. The results from the revision of the family Aeglidae, mainly from the study of the genus Aegla Leach, 1820, based on material collected in the southern and the south-eastern States of Brazil and on the examination of several collections from Brazilian and foreign institutions, are presented. Two diagnostic keys for the identification of the species of Aegla are included, one for the Brazilian, Uruguayan and north-eastern Argentinean representatives and another for the species from Chile and the remaining areas of Argentina. The results of the revision of 59 species of Aegla are presented, under the following headings: list of synonymies, type-material, diagnosis, description, size, examined material, geographic distribution and discussion. Illustrations of each species and of morphological details and maps recording known places of occurrence, with exception of A. intermedia Girard, 1855, a doubtful, never found again, species, with missing type-material, are included. The raw data from all measurements taken on samples and the results of statistical analysis are enclosed Four species are synonymized: A. neuquensis affinis Ringue let, 1948, A. montana Ringue let, 1960 and A. maulensis Bahamonde e López, 1963 are treated as junior synonyms of A. affinis Schmitt, 1942. A. lenitica Buckup & Rossi, 1977 is considered a junior synonym of A. prado Schmitt, 1942. Two subspecies have their status changed into species-level: A. paulensis Schmitt and A. affinis Schmitt. The knowledge about the areas of occurrence of nineteen species is extended. Twenty new species are described and illustrated: A. intercalata sp. n., A. ringueleti sp. n., A. septentrionalis sp. n. A. rossiana sp. n., A violacea sp. n., A. itacolomiensis sp. n., A. inconspicua sp. n., A ligulata sp. n., A marginata sp. n., A inermissp. n., A. spinosa sp. n., A. lata sp. n., A. jarais sp.. n., A. obstipa sp. n., A. spinipalma sp. n., A. grisella sp. n., A. longirostri sp. n., A. parva sp. n., A. leptochelas sp. n. and A. microphthalma sp. n. Lectotype and Paralectotype designations for A. scamosa Ringuelet,1948 are done. The results of the investigations support the hypothesis that the majority of the species of Aegla may not have very large areas of occurrence, living only in one basin or often in adjacent drainage basins.
