Hypoptopomatinae is a subfamily of catfishes (order Siluriformes) of the family Loricariidae.

Hypoptopomatinae is a monophyletic assemblage within the family Loricariidae.[1] It is composed by 17 genera and approximately 80 species.[2] This subfamily represents about one-tenth of all loricariid species.[3]

It is divided into two tribes, Hypoptopomatini and Otothyrini.[1] 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.[4]

In almost all species of hypoptopomatinae there is a diploid number of 2n = 54; this group is karyotypically very conserved.[5]

Hypoptopomatinae is distributed throughout cis-Andean South America from Venezuela to Northern Argentina.[2] 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.[6]
