Identity and locality
Aphanotorulus cf. emarginatus / Squaliforma cf. emarginata, classification disputed
Rio Xingu by Altamira, Brazil
Diagnostic evidence and naming
Historically labeled Hypostomus emarginatus, Squaliforma emarginata, and now often Aphanotorulus emarginatus complex. Original type locality uncertain; L011 identifies Xingu stock and is NOT proof that L035, L108 and other stocks share identical genetic provenance.
Breeding and genetics limitations
Large-growing fish; separate river locality from aquarium phenotype, and do not claim first successful breeder without firsthand proof.
