Each of the two monotypic groups is recognized as a separate species: Lilac-cheeked Kingfisher (Sangihe) Cittura cyanotis sanghirensis becomes Sangihe Lilac Kingfisher Cittura sanghirensis; and Lilac-cheeked Kingfisher (Sulawesi) Cittura cyanotis cyanotis becomes Sulawesi Lilac Kingfisher Cittura cyanotis. These two taxa show fairly deep levels of genetic divergence (Andersen et al. 2018), and have considerably different plumages (del Hoyo and Collar 2014, Eaton et al. 2016).
