Taxonomy
Pareiorhina brachyrhyncha was first formally described in 2005 by the Brazilian ichthyologists Carine Cavalcante Chamon, Arion Tulio Aranda and Paulo Andreas Buckup with its type locality given as Vera Cruz farm at 22°46'14.1"S, 45°26'42.5"W, in the neighbourhood of Ribeirão Grande, Ribeirão Grande (also known as the Teteqüera), in the municipality of Pindamonhangaba in the Brazilian state of São Paulo.[2] Eschmeyer's Catalog of Fishes classifies the genus Pareiorhina in the subfamily Hypoptopomatinae, the cascudinhos, within the suckermouth armored catfish family Loricariidae.[3]
Etymology
Pareiorhina brachyrhyncha is classified within the genus ''Pareiorhina, this name combines pareiá, meaning "cheek", with rhina, from rhínē, which means "file" or "rasp", this is probably an allusion to the rough sides of the head. The specific name, brachyrhyncha, means "short-snout", a referenece to the shape of its snout, which is short in comparison to the other species in the genus which were known when this species was described.[4]
