Hypostomus luetkeni ( Steindachner, 1877b)

Figure 4F

Geographic distribution: Paraíba do Sul river basin.

Diagnosis: Hypostomus luetkeni can be distinguished from H. affinis by the presence of 2 or 3 plates in the main post-supraoccipital series and the absence of ridges on the flanks of the body ( Mazzoni et al. 1994). Dark spots in the body, if present, are less conspicuous than in H. affinis .
