RESUMO

The species of the genus Callibaetis Eaton, unlike other members of the family, have been originally described based solely on alate stages, most of them inadequately. Despite the fact that the taxonomy of the family has improved in the last decades, the knowledge of the genus is still incipient. The aim of this study was to survey the species of Callibaetis in three municipalities of Amazonas state, as well as compiling taxonomic information on species of this genus deposited in various zoological collections in Brazil, and to develop an identification key for nymphs and adults of the species from Brazil. Samples were collected in artificial lakes, ponds, streams and floodplains in the cities of Manaus, Presidente Figueiredo and Iranduba. Nymphs collected were reared in the field, allowing their association with adults. Material from the following collections were examined: Universidade Federal de Pernambuco, Universidade Federal do Espírito Santo, Universidade Federal do Rio de Janeiro, Universidade Estadual de Campinas, Universidade do Estado do Mato Grosso, Universidade Comunitária da Região de Chapecó. The Brazilian species not collected were reviewed based on literature and photographs sent from museums. Seven new species were found and described based on nymphs and adults; males of C. jocosus were redescribed; and C. gonzalezi and C. sellacki were recorded for the first time from Brazil. The number of species of this genus known from Brazil increase from nine to eighteen after the present work, and the diagnosis of the previously known species, as of the genus were improved.
