Identity and locality
Ancistrus dolichopterus
Rio Negro basin, Brazil
Diagnostic evidence and naming
A distinct bristlenose species, often mislabeled as ordinary domestic Ancistrus. Confirm dorsal-ray counts, seam coloring, and source locality in full specimen dossiers. Eschmeyer’s Catalog of Fishes lists the 1854 Kner name, syntypes and Rio Negro basin occurrence; L183 should not be equated with all domestic bristlenose morphs.
Breeding and genetics limitations
Do not attribute common domestic longfin/albino origins to L183 without parentage documentation.
