Identity and locality
Baryancistrus chrysolomus (2011)
Rio Xingu / Rio Curuá drainage, Pará, Brazil
Diagnostic evidence and naming
Formally described in 2011. Adults retain a comparatively broad pale/yellow band along dorsal and caudal-fin edges. Compare with Baryancistrus xanthellus, whose distal yellow areas become restricted near the tips in adults. The original 2011 description distinguishes B. chrysolomus by dark, nearly unspotted body and yellow fin-edge bands from spotted B. xanthellus.
Breeding and genetics limitations
Habitat oxygenation and warm-water requirements should be established separately from wild climate measurements. No original breeding-line founder documented here.
