Identity and locality
Lasiancistrus heteracanthus (Günther, 1869)
Western South American drainages; exact original type locality pending catalog check
Diagnostic evidence and naming
2005 revision preserves the formal species and type of Lasiancistrus; relatively extensive small abdominal plates help separate from the unplated tentaculatus and saetiger. The Catalog of Fishes records the 1869 Chaetostomus original combination and current Lasiancistrus heteracanthus from the upper Amazon basin.
Breeding and genetics limitations
Male odontodes and abdominal plates are anatomy, not verified captive allele identities or F1/F2 inheritance results.
