Amaralia hypsiura is a species of catfish of the family Aspredinidae. The genus Amaralia is monotypic but there exists one undescribed species: Amaralia 'oviraptor' Friel, 1992, known from the Paraguay-Paraná River system [1][2]
Amaralia hypsiura are found throughout the Amazon River basin. They are medium-sized aspredinids (not exceeding 133 millimetres or 5.2 in SL). These fish have a deep, laterally compressed caudal peduncle, a reduced dorsal fin with only 2–3 rays, and well-developed head ornamentation.[1]
Amaralia species appear to be specialized to feed on the eggs of other catfishes; eggs found in Amaralia stomachs are thought to be those of loricariids.[1]
