Identity and locality
Panaque cf. armbrusteri 'Xingu'
Rio Xingu-labeled trade population, Brazil
Diagnostic evidence and naming
Specialist index lists Xingu form separately as Panaque cf. armbrusteri, including L027a. A geographic seller label is not an independently described taxon, domestically selected line or genetically proven population.
Breeding and genetics limitations
Ask for actual river collection documentation and first-person broodstock evidence. Do not cross unrelated L027 codes under assumed shared identity.
