          Abstract

          Abstract This paper describes the occurrence of digenetic Rhipidocotyle santanaensis Lunaschi, 2004 in Brazil. This parasite was found in the liver, heart, gonads, intestine, pyloric caeca, stomach, swim bladder and cavity of Acestrorhynchus lacustris (Lütken, 1875) from the Batalha River, São Paulo State, with higher incidence in gonads and digestive tract. The parasite specimens found in this study showed morphological characteristics very similar to specimens from Argentina, with differences only in relation to the ejaculatory duct and seminal vesicle. However, Brazilian specimens presented great morphometrical differences between specimens described in Argentina, with much higher measures. This is the first record of this metazoan parasite species in Brazil and in this host fish.

          Resumo O presente trabalho descreve a ocorrência do digenético Rhipidocotyle santanaensis Lunaschi, 2004 no Brasil. Estes parasitos foram encontrados no fígado, coração, gônadas, intestino, cecos pilóricos, estômago, bexiga natatória e cavidade do peixe Acestrorhynchus lacustris (Lütken, 1875) provenientes do rio Batalha, Estado de São Paulo, com maior abundância nas gônadas e trato digestório. Os espécimes dos parasitos encontrados neste trabalho apresentaram características morfológicas muito semelhantes aos espécimes provenientes da Argentina, com diferenças apenas em relação ao ducto ejaculatório e vesícula seminal. Porém, os exemplares brasileiros apresentaram grandes diferenças morfométricas entre os espécimes descritos na Argentina, com medidas muito superiores. Este é o primeiro registro desta espécie de parasito no Brasil e neste hospedeiro.
