簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 5 - 6; 臀鰭軟條: 6; 脊椎骨: 33 - 35. Differs from other members of the genus in having a relatively deep body (body depth at anus 6.0-7.8% SL vs. 4.2-5.8), anterior edge of pectoral spine with 29-34 serrations while posterior edge with 12-18 serrations. Can be differentiated further from Sisor rheophilus in having a wider nuchal plate (width 1.2-1.3 times length vs. width equal to length) (Ref. 55921).
在有一個方面有別於其他本屬的成員相當深的身體 (體高在肛門 6.0-7.8% SL vs.4.2-5.8), 胸棘的前緣有 29-34個鋸齒然而用 12-18個鋸齒的後緣。 能從 Sisor rheophilus 在有一個方面被區別進一步比較寬的頸背碟 (寬度 1.2-1.3 倍長度和寬度比較等於長度) 。 (參考文獻 55921)
