The Hypoptopomatinae are a subfamily of catfishes (order Siluriformes) of the family Loricariidae,[2] composed of 32 genera and approximately 265 species.[3] This subfamily represents about one-tenth of all loricariid species.[4]
Eschmeyer's Catalog of Fishes does not recognise tribes within the Loricariidae,[5] but other authorities have divided this taxon into three tribes, Hypoptopomatini, Neoplecostomini and Otothyrini. However, in a 2005 analysis, Otothyrini was found to not be monophyletic, with its representatives comprising a paraphyletic group in relation to the tribe Hypoptopomatini.[6] More recent phylogenetic evidence shows that Hypoptopomatini and Otothyrini, while each are monophyletic tribes, do not form a monophyletic subfamily, and therefore should each be recognized as their own individual subfamilies.[7] Problematically, the most recent Hypoptopomatine genera, Gymnotocinclus and Rhinolekos, were not classified in either of the tribes.[8][9] Gymnotocinclus was subsequently invalidated when it was synonymised with Corumbataia in 2019.[10]
Almost all species of Hypoptopomatinae have a diploid number of 2n = 54; this group is karyotypically very conserved.[11]
Hypoptopomatinae are distributed east of the Andes in South America from Venezuela to northern Argentina.[12] Most of the hypoptopomatine species are usually found at or near the water surface, typically in close association with riverbank vegetation or some subsurface structure.[13]
