Remark: See Le Bail et al. (2000:236, fig.) for complementary description with biological observations and geographical distribution; 12S and 16S mitochondrial rRNA gene sequences used in a molecular phylogeny of Loricariidae by Montoya-Burgos et al. (1998: figs. 3,4,6 as <i>Lasiancistrus niger</i>).
Comments: The most ubiquitous, frequently occurring and abundant species of this genus.  Occurs in all kinds of streams where the substrate is rocky and the water is flowing (Ref. 35381).  Found in  great numbers in zones of plunging waters (Ref. 27188).  May be found together with <i>Lithoxus</i> in little forest creeks as well as in rapids (Ref. 35381).
