Oxyropsis is a genus of freshwater ray-finned fishes belonging to the family Loricariidae, the suckermouth armored catfishes, and the subfamily Hypoptopomatinae, the cascudinhos. The catfishes in this genus are found in South America.
Oxyropsis was first proposed as a monospecific genus in 1889 by the ichthyologists Carl H. Eigenmann and Rosa Smith Eigenmann when they desribed O. wrightiana, which they also designated as its type species.[1] The Eigenmanns gave the type locality of this species as Lake Hyanuary in the Brazilian state of Amazonas.[2] The holotype was collected in 1865 by Louis Agassiz when he participated in the Thayer Expedition to Brazil.[3] Oxyropsis is classfied in the subfamily Hypoptopomatinae, known as cascudinhos, within the suckermouth armored catfish family Loricariidae, which is part of the suborder Loricarioidei within the catfish order Siluriformes.[4] Oxyropisis was reduced to a synonym of Hypoptopoma by Charles Tate Regan in 1904 as he regarded O. wrightiana as synonymous with Hypoptopoma carinatum, the validity of the genus was reconfirmed in 2002.[3]

Etymology
Oxyropsis combines oxys, meaning "sharp" or "pointed", with opsis, which means "face" or "appearance". The Eigenmanns did not explain this but it is thought to refer to the depressed head of the type species.[5]
