Reichard's seedeater was formerly placed in the genusSerinus but phylogenetic analysis using mitochondrial and nuclear DNA sequences found that the genus was polyphyletic.[3] The genus was therefore split and a number of species including Reichard's seedeater were moved to the resurrected genus Crithagra.[4][5] The stripe-breasted seedeater (C. striatipectus) was formerly conspecific, but was split as a distinct species by the IOC in 2021.[6]
