Identity and locality
Hypancistrus seideli
Lower rio Xingu, Brazil
Diagnostic evidence and naming
The 2025 original species description places L066, L236, L287, L333, L399 and L400 under Hypancistrus seideli. Different historical appearance codes are not independently described species. Exact captive pedigree, founders and Mendelian inheritance remain unverified. Original account explicitly cites this L399 hobby designation and notes color-pattern variability across individuals and geography.
Breeding and genetics limitations
Keep locality and founder/parent generation separately. Some seller line names have no demonstrated independent genetic ancestry.
