Identity and locality
Hypancistrus yudja
Middle rio Xingu, Brazil
Diagnostic evidence and naming
Formally described in 2025. Recorded in deeper (~15–40 m) lateritic rock formations, within the Belo Monte affected stretch; authors report severe conservation concern. Not a captive-selected derivative of L333. Independent 2025 specialist catalog also maps L174 to H. yudja; this does not prove any particular captive line, breeder, or F1/F2 inheritance pattern.
Breeding and genetics limitations
Published wild depth is habitat description, not an aquarium water-depth recommendation. Founder and breeding-line histories unresolved.
