簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 10; 臀鰭軟條: 35 - 36. Distinguished from other species of Cyanocharax by the large number of branched anal-fin rays (31-32 in the syntypes and 28-35, mostly 29-33) and the convex profile of the anal fin (Ref. 54760).
與其他種的 Cyanocharax 區分了藉由大量的分枝臀鰭棘條 (31-32 在 syntypes 中與 28-35, 大部份 29-33) 與臀鰭的中凸輪廓。 (參考文獻 54760)
描述: 臀鰭棘條 iv,32; iv,31. 背鰭鰭條 ii,8. 腹鰭鰭條 i,6. 胸鰭鰭條 i,10.(參考文獻 54760)
