Otothyropsis marapoama is a species of freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armored catfishes, and the subfamily Hypoptopomatinae, the cascudinhos. This catfish is endemic to Brazil.
Otothyropsis marapoama was first formally described in 2005 by Alexandre Cunha Ribeiro, Murilo de Carvalho and Alex Luiz de Andrade Melo with its type locality given as the Tietê River basin in the Municípality of Marapoama, at the Cubatão River, road beween Marapoama and Elisiárioat 21°11'35"S, 49°07'22"W.[2] When they described this species they classified it in the new genus Otothyropsis,[3] which is, by some authorities, classified in the tribe Otothyrini within the subfamily Hypoptopomatinae. Within this tribe, it represents a clade along with the genera Schizolecis, Otothyris and Pseudotothyris, which share unique specializations of the cranium associated with an enlarged swimbladder capsule. The degree of development of the swimbladder capsule in these genera was not found in any other member of the Otothyrini.[4] Otothyropsis has a sister group relationship with the clade Otothyris plus Pseudotothyris.[4] This genus is classified in the subfamily Hypoptopomatinae, the cascudinhos, in the suckermouth armored catfish family Loricariidae, in the suborder Loricarioidei on the catfish order Siluriformes.[5]
