Etymology: Hypostomus: Greek, hypo = under + Greek, stoma = mouth (Ref. 45335); sculpodon: From the Latin sculpo (to carve, cut, grave, or chisel in stone, brass, or wood) and from the Greek odon (tooth) in reference to the ability of the species to chisel wood with the teeth.

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).
Body shape (shape guide): elongated.
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)
