Closely related (with C. humii) to C. flavinucha. Hitherto treated as conspecific with C. humii, but differs in male’s small-spotted (not thickly streaked) throat, continuous on malar area (where in humii the spotting is denser and buffier) (3); crest rusty brown as on breast (bright pale yellow in humii), so that bright pale yellow is confined to hindneck, and in female the rusty-brown colour extends forwards as a supercilium to the lores (3); upperparts duller, plainer green (1); darker crimson vs rustier red wingpanel (ns); slightly smaller in bill (effect size –1.84; score 1) but longer in wing and especially tail (effect size 3.74; score 2). Monotypic.
