The mountain serin was formerly placed in the genus Serinus but a phylogenetic analysis of mitochondrial DNA sequences found that the species was not closely related to other member of Serinus nor to the geographically nearest finch, the Vietnamese greenfinch. The species was therefore assigned to a separate genus Chrysocorythus, a name that had previously been proposed by the German ornithologist Hans Edmund Wolters in 1967.
