Until recently considered conspecific with C. cyanoides, but genetic study pointed to its strong distinctiveness#R, and indeed it differs in its (in male) brighter and more contrasting blue on forecrown, cheek and wing-coverts (2); greyer vs greener blue of body colour (1); noticeably paler rump (1); (in female) duller brown, less rufous plumage, more obviously on underparts (ns[1]); (both sexes) smaller bill (effect size for length in males –2.19, score 2); notes of song rather flatter in pitch (1), without pause between first and second note (1)#R. Monotypic.

What do (1) and (2) mean? Learn more about the scoring system.
