Regan, 1904


The Neoplecostominae are a subfamily of catfishes (order Siluriformes) of the family Loricariidae. Species of Neoplecostominae live in high-montane, swift-flowing river habitats.[1]


Neoplecostominae are the most basal clade in Loricariidae with the exception of Lithogeneinae.[2] The genera of Neoplecostominae do not form a monophyletic assemblage.[3] Neoplecostominae is not diagnosed by any unique characteristic.[1] However, molecular studies have supported this grouping.[2]

Within the paraphyletic Neoplecostominae, Pareiorhina forms a monophyletic subunit that also includes Neoplecostomus.[4]
