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
colour 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%) . Aquarium Care: As with
most of this genus, will do well in a larger aquarium,
and the aquarium well filtered. Water parameters can
be quite diverse for this genera. Diet:
Wood eaters so would need soft wood in the aquarium.
Food tablets, pellets and vegeatable foods are also
taken along with insect larvae. Etymology:
The specific name is 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.
