Hypostomus chrysostiktos Birindelli, Zanata & Lima 2007

Can be easily diagnosed from most loricariids, except Megalancistrus, a few species of Chaetostoma, and some species of Pterygoplichthys and Delturus, by having high number of dorsal-fin branched rays (10-11). Can also be differentiated by having slightly evertible cheek plates (vs. fully evertible cheek plates of Chaetostoma, Megalancistrus, and most other Ancistrini and Pterygoplichthyini taxa; or absence of evertible cheek plates in Delturinae, Neoplecostominae, Hypoptopomatinae, Loricariinae, Corymbophanini and Rhinelepini). It further differs from Delturus by possessing four branched anal-fin rays (vs. five or six) and from several loricariids by having naked abdomen (vs. plated in e.g. Pterygoplichthys), snout almost completely plated leaving just a small naked area on its tip (vs. snout completely naked in e.g. Chaetostoma) (Ref. 75060).

Found in dark water stretches of rivers with rocky bottom, at altitudes from 50-662 meters above sea level (Ref. 75060).

Hypostomus chrysostiktos is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Paraguaçu River basin in Brazil. It is typically seen in blackwater portions of rivers with rocky substrates at elevations of 50 to 662 m (164 to 2172 ft) above sea level. The species reaches 26 cm (10.2 inches) SL and is believed to be a facultative air-breather.
