F. Moore, 1856,
Formerly included race waltoni, but this now found to be conspecific with C. eos (as HBW treated it), thereby becoming C. waltoni. Race davidianus recently given species rank, differing from nominate and argyrophrys by its cleaner, brighter, more contrasting underparts; broader, more obvious supercilium; different wing formula; squarer vs well-forked tail; shorter tail; larger bill; and notably different calls#R#R (morphological characters unverifiable for lack of access to specimens). Split accepted#R claiming corroboration by molecular study#R, but study in question does not conclude that davidianus merits species rank although it maps a record of race argyrophrys far inside the range of davidianus, which if correct certainly suggests two species. Further research required. Three subspecies recognized.
