Crested Fireback is split into two species, based on substantial differences in plumage (del Hoyo and Collar 2014, Eaton et al. 2016). Note that although apparent hybrids have been reported (Delacour 1949, van Marle and Voous 1988), apparently pure birds occur very near this region (Eaton et al. 2016); it also is possible that these reports of birds with intermediate characters were based on trade skins of captive hybrids, rather than a wild population (F. Rheindt). As a result the monotypic group Crested Fireback (Malayan) Lophura ignita rufa becomes Malayan Crested Fireback Lophura rufa; and the monotypic group Crested Fireback (Bornean) Lophura ignita ignita becomes Bornean Crested Fireback Lophura ignita.
