Abstract The genus Tetranematichthys has only three species, and none of them have undergone cytogenetic analyses. Therefore, this study brings for the first time the analysis of Tetranematichthys wallacei, collected from the Igarapé Apaú, Guamá R

Abstract The aim of this paper was to present the second case of B chromosomes in Auchenipteridae (Trachelyopterus sp.), and to test the hypothesis that the B chromosomes of this species and Parauchenipterus galeatus might have a common origin, since

ABSTRACT Historically, there are divergences in the species allocation between Centromochlus and Tatia. This study aimed to generate the first cytogenetic data about Centromochlus and, by analyzing a population of Centromochlus heckelii from the Amaz
