Volcán de Miravalles.
Previously considered conspecific with A. cyanifrons. Status has been difficult to resolve, being known from a single specimen; apparently closely related to A. cyanifrons, but has a slightly longer bill, paler and less extensive blue cap, more continuously green chin to belly, richer russet uppertail-coverts, and bluish-black undertail-coverts with narrow whitish edges; a hybrid origin is most unlikely for phenotypical reasons, and species status has been validated by independent commentators#R#R; lack of records since 1895 raises possibility of extinction. Monotypic.
