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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00760 - 0.03623), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
回復力 (Ref.
120179): 低い, ４．５年～１４年の倍増期間の最小個体群 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (29 of 100).
