In 1924, LUTZ in his work "Estudos sobre a evolução dos Endotrematodeos brazileiros", proposed six new species under the genus Echinostoma and described them although without offering many details. For this reason, it was not possible to achieve a complete knowledge of these species and as almost the whole material studied by LUTZ was encolosed in the Oswaldo Cruz Helminthological Collection, the authors revised it, presenting redescriptions of the species, as well as original camera lucida drawings, in order to facilitate further investigations on the matter.
