Until recently considered conspecific with C. banyumas, but differs from geographically closest (possibly sympatric or parapatric) form C. b. whitei in its larger bill and longer wing (effect size 6.23 for male bill based on published data#R; score 3); marginally shorter tail (effect size –1.13; score 1); paler leg colour (1); paler and less extensive orange-rufous breast colour (both sexes) (1); cooler, paler blue frontal band (in male) (1); strong vs weak or non-existent migratory habit (ns). Song is distinctive in relation to mainland forms of C. banyumas, but much less so when compared with Javan and Bornean taxa#R. Monotypic.
