Identity and locality
Lasiancistrus tentaculatus Armbruster, 2005
Río Orinoco basin, Venezuela/Colombia collection region
Diagnostic evidence and naming
Original 2005 genus revision describes males with small membranous tentacules along snout margin, distinguishing them from other Lasiancistrus with whiskerlike snout odontodes. Abdomen unplated. The 2005 description distinguishes nuptial male snout tentacles from whiskerlike odontodes of related Lasiancistrus; the Catalog of Fishes confirms the name and Orinoco provenance.
Breeding and genetics limitations
Nuptial male morphology is not an inherited captive-selected line and is not equivalent to common Ancistrus whiskers.
