For a long period this bird was known only from three nineteenth-century specimens. It was rediscovered in 1991. The current population is estimated at less than 250, and it is classified as critically endangered by the IUCN.[1] The main threat is habitat destruction.

The São Tomé grosbeak was formerly placed in the genus Neospiza (meaning "new finch"[2]) but was assigned to the genus Crithagra based on a phylogenetic analysis of mitochondrial and nuclear DNA sequences.[4][5]
