Identity and locality
Hypancistrus sp. L028 (L004 complex)
Rio Guamá by Ourém, Brazil, according to specialized index
Diagnostic evidence and naming
The L028 code has a different attributed collection stream from L004 and L005 although specialist catalogue groups them in the Angelicus Hypancistrus complex; do not equate shared species-complex identity with interchangeable provenance. The independently indexed L028 population is attributed to Rio Guamá near Ourém, geographically distinct from L004/L005 Rio Tocantins forms and L073 Portel specimens. Related hobby forms should retain provenance-specific records.
Breeding and genetics limitations
Cave-spawning documentation should retain geography and parent IDs; published hobby evidence does not prove a line founder.
