Taxonomy
editParotocinclus jacksoni was first formally described in 2021 by the Brazilian ichthyologists Telton Pedro Anselmo Ramos, Silvia Lustosa-Costa, Luciano Freitas Barros-Neto and José E. L. Barbosa with its type locality given as the Fechado River, a tributary to the Mamanguape River, in the municipality of Arara, in the Brazilian state of Paraíba at 06°54'33"S, 35°39'02"W.[1] Eschmeyer's Catalog of Fishes classifies the genus Parotocinclus in the subfamily Hypoptopomatinae, the cascudinhos, within the suckermouth armoured catfish family Loricariidae.[2]
Etymology
editParotocinclus jacksoni is classified in the genus Parotocinclus, is a combination of para, meaning "near", and the genus Otocinclus, the genus the type species, P. maculicauda was originally thought to be a member of. The specific name, honours the Brazilian composer and singer of Forró and Samba, José Gomes Filho, whose stage name was Jackson do Pandeiro and who was a native of Alagoa Grande, a municipality on the Mamanguape River basin where the type locality of tis species is located.[3]
Description
editParotocinclus jacksoni reaches a standard length of 3.5 cm (1.4 in). This species can be told apart from almost all other species in its genus by its abdomen having a small number of small and scattered platelets. It has a laterally exposed pectoral girdle which supports odontodes, apart from at its symphysis. It also differs in its coloration and pattern, teh size of its lower lip and numbers of teeth.[4]

The riparian vegetation is mainly dense scrub with scattered trees. This species has been collected in association with Hypostomus pusarum, Rhamdia quelen, Astyanax bimaculatus, Psalidodon fasciatus, Compsura heterura, Characidium bimaculatum, Saxatilia brasiliensis, Hoplias malabaricus, Leporinus piau, Poecilia reticulata, Serrapinnus piaba, Steindachnerina notonota and Triportheus signatus.[4]
