Hypostomus eptingi

Hypostomus eptingi is a disputed species of catfish in the family Loricariidae. It is native to South America, where it occurs in northeastern Brazil. It reaches 12.2 cm SL and is believed to be a facultative air-breather.
In 2017, Telton Pedro A. Ramos, Cláudio H. Zawadzki, Robson T. Ramos and Heraldo A. Britski found H. eptingi to be a junior synonym of Hypostomus johnii after a redescription of the latter. FishBase follows the aforementioned classification and lists H. eptingi as a synonym of H. johnii, whereas ITIS lists H. eptingi as a valid species.
