脊椎骨: 42 - 44. Both sides of the body with 7-11 large and blackish spots. Deep body with clearly convex dorsal profile. Head length shorter than body depth. Snout length shorter or equal to postorbital head length. Lips not developed, lateral lobes of lower lip narrow, without folds, the median process large and marked. Barbel length slightly thick, 1/2-2/3 of eye diameter. Dorsal spine strong, equal to HL. Origin of dorsal fin nearer the tip of snout than the caudal base (Ref. 38453). Anal fin with 6 1/2 branched anal rays; last simple dorsal ray ossified, spine-like (Ref. 43281).
身体有 7-11 大而黑色的斑点两边。 身体纵深具有清楚中凸的背面轮廓。 头长短于体高。 吻的长度比较短的或等于眼眶后的头长。 唇不被发展, 下唇的侧叶狭窄的, 没有摺层，中动脉突起大而显着的。 触须长度些微厚, 眼直径中的 1/2-2/3。 背棘强的, 等于 HL。 超过尾鳍基底的吻尖附近的背鳍起点.(参考文献 38453) 臀鳍有 61/2 分枝的臀鳍鳍条; 最后的单一背鳍鳍条钙化了, 像棘一样的.(参考文献 43281)
Adults usually found in streams and creeks with moderate flow and sandy bottom (Ref. 43281). Feed mainly on insects and mollusks in summer and on crustaceans in winter (Ref. 1441)
通常发现于溪流与小溪有中等的水流与沙质底部。 (参考文献 43281) 在夏天主要吃昆虫与软件动物而且冬天时捕食甲壳动物 (参考文献 1441)

Bayesian length-weight: a=0.00794 (0.00660 - 0.00956), b=3.13 (3.08 - 3.18), in cm total length, based on LWR estimates for this species (Ref.
93245).
营养阶层 (Ref.
69278): 3.5 ±0.47 se; based on food items.
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (tm=3).
Fishing Vulnerability (Ref.
