簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 10; 臀鰭軟條: 7. Distinguished from Erromyzon compactus by having fewer bars on flank (12 vs. 16-18), a more compact body with pectoral fin extending further backward (3/4 of distance to pelvic-fin origin, vs. 1/2) and pelvic fin reaching anus (vs. not), caudal peduncle as deep as long (vs. depth 1.1-1.3 times in length), a shorter snout (69 % HL, vs. 77-86) and smaller eye (45% HL, vs. 54-56). Possesses numerous tubercles on snout, cheek and opercles, which are missing in E. sinensis, but their development might depend on season and sexual maturity (Ref. 54043).
與 Erromyzon compactus 在側面 (12 vs.16-18) 上藉著具有較少的橫帶區分了, 一個比較緊密的身體有胸鰭向後地 (對腹鰭起點的距離中的 3/4, vs.1/2) 延伸進一步與腹鰭達到肛門 (vs. 不) ，尾柄深達長的 (vs. 深度 1.1-1.3 倍長), 一個較短的吻 (69% HL, vs.77-86) 與較小的眼.(45% HL, vs.54-56) 在吻，頰與鰓蓋上持有很多的小瘤, 那是 E. sinensis 中失去，但是他們的發展可能仰賴季節與性成熟。 (參考文獻 54043)
描述: 背鰭有 3 單一的與 71/2個分支條; 臀鰭有 2 單一的與 5 1/2 分支條; 胸鰭有 1 單一的與 17個分支條; 而且腹鰭有 1 單一的與 8個分支條.(參考文獻 54043)
Collected during rainy season from swift flowing, turbid water over large boulders (Ref. 54043).
