简单描述
型态特徵 | 形态测量图
Distinguished from all other members of the Hypostomus cochliodon group except H. hemicochliodon by having a buccal papilla and intermediately developed teeth (juveniles of H. cochliodon and H. taphorni occasionally also have intermediate teeth). Differs from H. hemicochliodon by having brownish-red coloration with widely spaced spots vs. dark brown with closely spaced spots, by having a smaller dorsal-anal length to anal-fin length ratio (average=79.2%, 69.6-89.7% vs. average=111.1%, 92.5-132.6%) and almost completely by having a smaller interorbital width/HL ratio (average=51.4%, 38.5-45.4% vs. average=49.9%, 44.1-55.6%) (Ref. 50589).
藉由有一个除了 H. hemicochliodon 以外与 Hypostomus cochliodon 群的所有其他成员区分了口的乳突而且中间地发展齿。 ( H. cochliodon 与 H. taphorni 的稚鱼偶然地也有中间的齿) 有别于 H. hemicochliodon 用空隙大的斑点借着具有红褐色的颜色 vs. 深褐色的具有间隔很密的斑点, 藉由有一个较小的背鳍、臀鳍长度到臀鳍长度比 (平均的=79.2%, 69.6-89.7% vs. 平均的=111.1%, 92.5-132.6%) 與幾乎完全地藉由有一個較小的眼間骨寬度/HL 比 (平均的=51.4% ， 38.5-45.4% 和 average=49.9% 比較, 44.1-55.6%).(參考文獻 50589)
