Biology:Neoplecostomus
Neoplecostomus is a genus of freshwater ray-finned fishes belonging to the family Loricariidae, the suckermouth armored catfishes, and the subfamily Hypoptopomatinae, the cascudinhos. The catfishes in this genus are found in South America.[1]
Taxonomy
Neoplecostomus was first proposed as new subgenus of Plecostomus in 1888 by the German-American ichthyologist Carl H. Eigenmann and his ichthyologist wife Rosa Smith Eigenmann with Plecostomus microps designated as its type species.[2] P. microps was originally described in 1877 by the Austrian ichthyologist Franz Steindachner with its type locality given as Rio de Janeiro, maybe the Parahyba River.[3] This genus is sometimes placed in the subfamily Neoplecostominae[4] but Eschmeyer's Catalog of Fishes classifies this genus in the subfamily Hypoptopomatinae, the cascudinhos, within the suckermouth armored catfish family Loricariidae.[2]
Etymology
Neoplecostomus 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.[5]

Characteristics
Neoplecostomus catfishes can be distinguished from all other loricariids by a modified shield of small plates on the abdomen with posteriorly directed odontodes; the shield appears to act as a holdfast. The color pattern is generally mottled brown with the abdomen white. The head is long, rounded, and shovel-shaped. The fin spines are weak.[11] They range from about 8 to 11 cm (3.1–4.3 in) SL.[1]
Distribution and habitat
Neoplecostomus catfishes are endemic to Brazil where they live in fast-flowing water.[11]
