成熟度: Lm ?  range ? - ? cm
Max length : 8.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188)
背棘 (總數) : 0; 背的軟條 (總數) : 13 - 21; 臀棘: 0; 臀鰭軟條: 15 - 18; 脊椎骨: 43. 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.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
主要地與非常相似的 R. amazonica 區分在側線列中藉著具有更多的脊椎骨與更多的鱗片。 於大約眼中心的水平容易地在顎骨的上半部上在區域中與所有的其他鯡魚分開了藉由銳利的逆向棘。 一條銀色的斑紋沿著被一些作者被報告的側面。 二在鱗片上明顯的平行陷紋。
