Identity and locality
Pseudacanthicus major Chamon & Costa e Silva, 2018
Rio Tocantins basin, Brazil
Diagnostic evidence and naming
Original 2018 scientific description identifies exceptionally large Pseudacanthicus with a dark brown unspotted body and white transverse bands on dorsal and caudal fins. Distinct from L024 P. pitanga and L025 P. pirarara. Pseudacanthicus major was described in 2018 from the Tocantins basin, Brazil. Its large body and diagnostic fin bands are species characters, not an invented giant-color pedigree.
Breeding and genetics limitations
No original captivity color strain or breeding pedigree; size and territorial requirements differ dramatically from small Hypancistrus.
