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..
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
South America: Rio Amazonas in Peru, Ecuador and Brazil, and the upper Rio Negro drainage and the upper Rio Orinoco drainage in Venezuela.

Morphology | Morphometrics
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).
Facultative air-breathing in the genus (Ref. 126274)

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 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
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100).
