Revisão taxonômica dos caranguejos de água doce brasileiros da família Pseudothelphusidae (Crustacea, Decapoda)

Abstract

The collections of freshwater crabs of the family Pseudothelphusidae deposited in the Instituto Nacional de Pesquisas da Amazônia, Museu de Zoologia da Universidade de São Paulo and Forschungsinstitut Senckenberg were studied. Redescriptions of the species that occur in Brazil are made, with notes on the ecology and geographic distribution. A new species of Kingsleya for the Trombetas, Curuá- Una and Uatumã rivers is described and new records, including one of Fredius reflexifrons to Peru, are reported. A terminology in Portuguese for the gonopodal stmctures is proposed. Keys to genera and species are given either in Portuguese or in English, as well as a map of the geographic distribution of this family in Brazil.
