Acestridium discus is a species of freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armored catfishes, and the subfamily Hypoptopomatinae, the cascudinos.[2] This catfish is endemic to Brazil where it occurs in the basin of the Rio Negro in the state of Amazonas.[1] A. discus was first formally described in 1911 by the American ichthyologist John Diederich Haseman with its type locality given as Igarapé de Cachoeira Grande, near Manaus.[2] When Haseman described this species he classified it in the new monospecific genus Acestridium , meaning that A. discus is the type species of that genus by monotypy.[3] This species reaches a standard length of 6.7 cm (2.6 in).[4]
