Issue
New combination with type species designation by Bleeker (1862:2); information on the holotype and type locality in Isbrücker (1992); complementary descriptions in Günther (1864:242) and in Regan (1904:229); recent material redescribed with ecological observations in Le Bail et al. (2000:234, fig.). Mitochondrial D-loop sequences used in a molecular phylogeny of Hypostomus and related genera by Montoya-Burgos and Weber (in press, fig. 2; EMBL/GenBank AJ318368).

Facultative air-breathing in the genus (Ref. 126274); Lives in the main jets of rapids where the current is very strong. The substrate consists of bulky rocks which gives them shelter. Occurs together with the following species: Leporinus granti, Astyanax meunieri, Bryconops caudomaculatus; Parodon guyanensis, Harttia surinamensis, Hypostomus gymnorhynchus, Lasiancistrus brevipinnis and Heptapterus longior (Ref. 35381).
