Taxonomy
Pareiorhaphis garapia was first formally described in 2015 by Edson H. L. Pereira, Pablo César Lehmann A., Lucas J. Schvambach and Roberto Esser dos Reis with its type locality given as the Arroio Garapiá, upstream of the Garapiá Waterfall, Maquiné, Barro do Ouro, in the state of Rio Grande do Sul.[1] Eschmeyer's Catalog of Fishes classifies the genus Pareiorhaphus in the subfamily Hypoptopomatinae, the cascudinhos, within the suckermouth armored catfish family Loricariidae.[2]
Etymology
Pareiorhaphis garapia is a species in the genus Pareiorhaphis, the name of which is a combination pareio, derived from pareiá, which means "cheek" in Greek, and rhaphis, meaning "needle". This is a reference to the needle like hypertrophied odontodes on the cheeks of the males when they are in breeding condition. The specific name, garapia, refers to the type locality, the Arroio Garapiá, as well as the waterfall which limits the distribution of this catfish.[3]
