Diagnosis

Distinguished from the very similar R. amazonica mainly by having more vertebrae and more scales in lateral series. Easily separated from all other clupeids in the area by the sharp retrorse spine on the upper part of the maxilla at about the level of the eye center. A silver stripe along the flank reported by some authors. Two distinct parallel striae on scales.
