MONOPHYLY OF EIGENMANNIA TRILINEATA View in CoL SPECIES- GROUP

All genera of the Sternopygidae (see comparative material examined) were used for the purpose of character polarization. The results revealed a putative synapomorphy that supports the monophyly of the E. trilineata species group ( Eigenmannia antonioi sp. nov., Eigenmannia desantanai sp. nov., Eigenmannia guairaca sp. nov., Eigenmannia matintapereira sp. nov., E. microstoma , Eigenmannia muirapinima sp. nov., Eigenmannia pavulagem sp. nov., E. trilineata , E. vicentespelaea , and Eigenmannia waiwai sp. nov.): presence of a superior medial stripe. The species of the Eigenmanniinae lack a stripe characterized by a concentration of chromatophores between the lateral line and the proximal portion of the pterygiophores of the anal fin. In contrast, this character is uniquely present in all species of the E. trilineata species group. This feature is consequently hypothesized to be an exclusive synapomorphy for the E. trilineata species group.
