Baryancistrus chrysolomus
Baryancistrus xanthellus

Two new species of the hypostomine genus Baryancistrus are described from the rio Xingu drainage. Baryancistrus xanthellus is distinguished from all other Baryancistrus species by the presence of yellow spots along the entire body and conspicuous yellow marks on distal tip of dorsal and caudal fins. Baryancistrus chrysolomus is distinguished from its congeners by its uniform dark body coloration and presence of yellow bands on dorsal and caudal fins. Despite the lack of formal description, these species are very popular in the international aquarium trade. We expect that these formal descriptions might contribute to the improvement of Brazilian regulations in the international trade of ornamental loricariids.

У "голден нагет"а известны две (или даже три?) "морфы" , данная работа описывает их как один вид?

Да, все 3 морфы, имеющие различный размер точек, отнесены к одному виду.
