Taxonomy
editNeoplecostomus ribeirensis was first formally described in 2012 by the Brazilian ichthyologist Francisco Langeani-Neto with its type locality given as a stream off the Bananal River, Ribeira River basin, 7 km (4.3 mi) from the road between Biguá and Iguapé in the Brazilian state of São Paulo.[2] Eschmeyer's Catalog of Fishes classifies the genus Neoplecostomus in the subfamily Hypoptopomatinae, the cascudinhos, within the suckermouth armored catfish family Loricariidae.[3]
Etymology
editNeoplecostomus ribeirensis is classified within the genus Neoplecostomus, this name prefixes neo-, for "new" onto plecostomus, as this genus was proposed as a subgenus of Plecostomus, now known as Hypostomus and classified in the subfamily Hypostominae. The specific name, ribeirensis, puts the Latin suffix -ensis, which denotes a place, onto ribeira, denoting the Ribeira de Iguape River basin where this catfish is endemic.[4]
Description
editNeoplecostomus ribeirensis has an elongated body shape and it reaches a standard length of 9 cm (3.5 in).[5]
Distribution
editNeoplecostomus ribeirensis is endemic to Brazil where it is only known from the Ribeira de Iguape river basin. It has been reported from the Tibagi and Iguaçu river basins but these reports need confirmation. Within the Ribeira de Iguape river basin this catfish has been recorded from Corujas river, Tapiraí in the Serra de Paranapiacaba, the Ipiranga, Água Doce, Pilões and Betari river basins[1]
