Abstract:
A new species of Eigenmannia is described from the Rio Paraná (the Grande, Paranapanema
and Tietê basins). This new species is distinguished from all congeners by
colouration pattern, position of the mouth, relative depth of posterodorsal expansion
on infraorbitals 1 + 2, number of teeth, osteological features, number of rows of
scales above lateral line (LL) and morphometric data. Comments on the widened
cephalic lateral-line canals of Sternopygidae and a dichotomous key to the species of
Eigenmannia from the Rio Paraná Basin are provided.
