Deuterodon intermedius Eigenmann, 1908

Fig. 3H

Distribution.

Rio Paraíba do Sul basin and coastal drainages in state of Rio de Janeiro, Brazil.

Diagnosis.

Deuterodon intermedius can be distinguished from its congeners of the study area by the absence of space in the symphysis of dentary; five tetracuspidate to hexacuspidate teeth in the inner series of the premaxillae; infraorbital 3 without chromatophores; small humeral spot, sometimes slightly rounded in smaller specimens; no more than 1.5 scales below the lateral line; 35-37 perforated scales in the lateral line

Remarks.

Deuterodon intermedius is described from the rio Paraíba do Sul basin. However, in the present study it was found in the rio Doce basin. The only difference observed in the specimens between both morphotypes is a tendency of longer length in adult specimens from the rio Paraíba do Sul basin.
