Hypoptopomatinae

Otocinclus is a genus of catfish in the family Loricariidae native to South America, commonly known as "dwarf suckers" or "otos". This genus, like other loricariids, is characterized by rows of armour plating covering the body, as well as the underslung suckermouth. They are generally small in size; O. tapirape is the smallest of the species (2.4 cm), while O. flexilis is the biggest (5.5 cm). These species have adaptations that allow them to breathe air. A duct forms at the junction between the esophagus and the stomach and expands into an enlarged, ring-like diverticulum, character

The color pattern is usually dark brown and mottled with the abdomen white. Most species in to Pareiorhaphis were originally described in Hemipsilichthys. In 1918, Alípio de Miranda-Ribeir

These species are distinguished by the presence of a single row of enlarged odontodes along the trunk midline lying adjacent and immediately dorsal to, the lateral line canal. Species of this genus have a depressed head and have relatively large eyes placed ventrolaterally. This genus is most similar to Hypoptopoma in external appearance, which shares the head shape and eye placement. Oxyropsis are elongate and have a narrow caudal peduncle, which distinguishes it from all other Hypoptopomatinae genera except Niob
