Vanua Levu, Fiji.
Commonly treated as conspecific with E. cyaneovirens, and geographical position between subspecies of latter species (which see) problematic. Nevertheless, differs in its black vs blue chin and throat (3); reduced blue on breast, shading quickly to green (1); red of crown stopping at hindneck, nape thus being green and not red, and with no adjacent blue on mantle (3); smaller size (effect size for bill vs E. c. cyaneovirens −5.69, vs E. c. regia −4.07; score 2); use of forest edge and open areas, including gardens and suburbs, feeding frequently on lawns, vs restricted to closed-canopy forest, feeding largely in trees (1). Monotypic.
