Each of the two monotypic groups is recognized as a separate species: Blue-banded Kingfisher (Malaysian) Alcedo euryzona peninsulae becomes Malaysian Blue-banded Kingfisher Alcedo peninsulae, and Blue-banded Kingfisher (Javan) Alcedo euryzona euryzona becomes Javan Blue-banded Kingfisher Alcedo euryzona. The lack of clinality in the rather striking plumage differences (del Hoyo and Collar 2014; see also Eaton et al.) within the ranges of the two taxa, despite the fact that Sumatra and Java have been connected for most of the Pleistocene, is here taken as evidence of parapatry and thus species status.
