簡短描述
型態特徵 | 形態測量圖
脊椎骨: 40 - 41. Differs from all other species of the genus by the number of cusps on the row of internal premaxilla teeth (3-5 vs. 5-7 except Hemibrycon surinamensis), the number of predorsal scales (10-12 vs.12-17, except Hemibrycon jelskii and Hemibrycon orcesi ), and by postcleithrum 1 much closer to postcleithrum 2 (vs. postcleithrum 1 and 2 clearly separated).
Inhabits clear water with stone and sand substrates (Ref. 77138).
