Remark: See Le Bail et al. (2000:238, fig.) for complementary description with biological observations and geographical distribution.
Comments: The smallest among the Guianese <i>Lasiancistrus</i> since it hardly reaches 10 cm TL.  Prefers the rapid zones where the depth is shallow, the substrate is rocky and the illumination is moderate.  Found in association with <i>Lasiancistrus brevispinis</i>, <i>Cteniloricaria fowleri</i>, <i>Ancistrus aff. temminckii</i> and <i>Genicichla ternetzi</i>.  Its small size, odd shape and bright coloration make this species especially interesting for aquarists (Ref. 35381).
