Differs from Discogobio brachyphysallidos, the only other species of the genus in Yuanjiang drainage in China, by scales on breast and belly extending forward at least to posterior extremity of pectoral-fin base; an irregular and faint stripe along flank from anal-fin origin backwards, darker posteriorly, and with contrasting edges on caudal peduncle (Ref. 55924). Can be differentiated from all its congeners by the following characters: oral sucking disc large with posterior edge beyond vertical of anterior margin of eye; snout with small tubercles; body depth more than 17.2% of SL; scaled on breast and belly or naked restricted to belly (Ref. 75176).
有别于 短鳔盘鮈〔Discogobio brachyphysallidos〕 , 在中国的沅江流域的唯一其他种的本属, 借着鳞片在向前延伸胸鳍基底的至少到在后部末端的胸部与腹面上; 一条不规则而模糊的斑纹向后沿着来自臀鳍起源的侧面, 比较深色的在后部地, 而且有对比鲜明的边缘在尾梗上.(参考文献 55924)
Adults inhabit torrential water of mountain area, clinging to the substrata on bottom by the sucking disc of mouth (Ref. 38450). Local people claim that this fish feeds mainly on algae (Ref. 75176).
栖息于被在底部上附着于下层土壤用它的嘴部吸盘的山区域的奔流水。 (参考文献 38450)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00665 - 0.01894), b=3.04 (2.90 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
