Oxyropsis carinata is a species of freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armored catfishes, and the subfamily Hypoptopomatinae, the cascudinhos. This catfish is found in South America, where it is found in the Amazon basin.
Oxyropsis carinata was first formally described as Hypoptopoma carinatum in 1879 by the Austrian ichthyologist Franz Steindachner with its type locality given as "tributaries of the Amazon at the border of Peru".[2] This catfish is now classified in the genus Oxyropsis which is within the subfamily Hypoptopomatinae[3] and which was formerly considered to be a junior synonym of Hypoptopoma, until restored as a valid genus in 2002 by Adriana E. Aquino and Scott A. Schaefer.[3][4]
Etymology
Oxyropsis carinata is one of three valid species in the genus Oxyropsis, the name of which combines oxys, meaning "sharp" or "pointed", with opsis, which means "face" or "appearance". The describers of the genus, C. H. Eigenmann and R. S. Eignemann, did not explain this but it is thought to refer to the depressed head of the type species, O. wrightiana. The specific name, carinata, means "keeled", an allusion to the serrated ridge along the sides of this species.[5]
