          Abstract

          Samples of Crenicichla iguassuensis and a morph from the Iguaçu River which differed from C. iguassuensis by its lips morphology were examined by isozyme starch electrophoresis technique. The analysis of 27 enzyme loci exhibited a genetic identity of 0.993 between the two morphs. No diagnostic locus was found that permitted to distinguish the two Crenicichla morphs. The data obtained in this investigation did not support the existence of two distinct species for this genus in the Iguaçu River, which suggested that the morphs stood for two polymorphic forms of Crenicichla iguassuensis.

          Amostras de Crenicichla iguassuensis e de um morfótipo do rio Iguaçu que difere de C. iguassuensis pela morfologia dos lábios foram analisadas pela técnica da eletroforese de isozimas em gel de amido. A análise de 27 loci enzimáticos revelou uma identidade genética de 0,993 entre as duas formas. Não foi encontrado nenhum locus diagnóstico que permitisse diferenciar os dois morfótipos de Crenicichla. Os dados obtidos nesta pesquisa não apóiam a existência de duas espécies distintas do gênero Crenicichla no rio Iguaçu. Os dados sugerem que as duas formas representam um polimorfismo da espécie Crenicichla iguassuensis.
