Neoplecostomus corumba is a species of freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armoured catfishes, and the subfamily Hypoptopomatinae, the cascudinhos. This catfish is endemic to Brazil.
Taxonomy
[edit]Neoplecostomus corumba was first formally described in 2012 by the ichthyologists Cláudio Henrique Zawadzki, Carla Simone Pavanelli and Francisco Langeani with its type locality given as the stream of Gameleira, a tributary of Corumbá River, in the Paranaíba basin at 17°59'S, 48°29'W, in the Municipality of Corumbaíba, in the Brazilian state of Goiás.[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
[edit]Neoplecostomus corumba 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, corumba, refers to the Corumba river drainage, in which the type locality is located.[4]
Description
[edit]Neoplecostomus corumba has a single spine and 7 soft rays in its dorsal fin and a single spine and 6 soft rays in its anal fin. It has an elongated bosy shape with a depressed cross section and recahes a standard length of 8.1 cm (3.2 in). The upper body is almost completely covered in dermal plates, except for a naked areas around the base of the dorsal fin and the tip of the snout. The lower surface of the head i snaked aprt from a small odontode bearing plate in front of the gill slit, with dermal platelets found between the pectoral and pelvic fins. All of the main fins have a spine and these spines all have odontodes on them, except for the spine in the dorsal fin, an adipose fin is always present.[5]
Distribution
[edit]Neoplecostomus corumba is endemic to Brazil where it is known only from its type locality Gameleira stream, a tributary of the Corumbá River, Paranaíba River basin, Corumbaíba, Goiás.[1]
