Etymology: Hypostomus: Greek, hypo = under + Greek, stoma = mouth (Ref. 45335); hemicochliodon: From the Latin hemi (half), and the Latin coclea (coch-) (spoon), and the Greek odon (tooth), in reference to the fact that the teeth are about half as spoon-shaped as those of wood-specializing members of the Hypostomus cochliodon group..

Distinguished from all other members of Hypostomus cochliodon group except H. sculpodon by having a medium-sized buccal papilla, intermediately developed teeth and a large patch of odontodes on the opercle. Differs from H. sculpodon by its dark brown color with closely spaced spots, by having a greater dorsal-anal length to anal-fin length ratio (average=111.1%, 92.5-132.6% vs. average=79.2%, 69.6-89.7%) and almost completely by having a larger interorbital width/HL ratio (average=49.9, 44.1-55.6% vs. average=51.4%, 38.5-45.4%) (Ref. 50589).
除了 H. sculpodon 以外与 Hypostomus cochliodon 的所有其他成员区分群藉由有一个，中等大小的口乳突,中间地在鳃盖上发展了齿与一个齿的大小区块。 有别于 H. sculpodon 用它的深褐色的颜色具有间隔很密的斑点, 藉由有一个较大的背鳍、臀鳍长度到臀鳍长度比 (平均的=111.1%, 92.5-132.6% vs. 平均的=79.2%, 69.6-89.7%) 与几乎完全地藉由有一个较大的眼间骨宽度/HL 比 (平均的=49.9,44.1-55.6% 和 average=51.4% 比較, 38.5-45.4%).(參考文獻 50589)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00681 - 0.02326), b=2.99 (2.84 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
