Closely related to C. gallicus and C. pectoralis; all three often considered conspecific, as mixed pairs reported, but see C. gallicus. Differs from C. gallicus in its unmarked vs spotted lesser underwing-coverts (2), darker, more contrasting band on trailing edge of underwing (2), uniformly dark upperwing-coverts vs pale patch on same (ns[2]), narrower barring vs coarser barring on belly (ns[1]), and brown-bodied juvenile vs juvenile like adult (3)#R; and from C. pectoralis in its paler head and neck (2), barred vs plain white belly and underwing-coverts (3), and brown-bodied vs rufous-bodied juvenile (3). Monotypic.
