1 For formal introduction of this family-group name see Tello et al. (2009) [Tello, 2009 #12002].
2 For reasons to treat the mexicanus group as conspecific with coronatus see Ridgely & Tudor (1994) [Ridgely, 1994 #3272].
3 Probably comprises multiple species, see Fitzpatrick (2004) [Fitzpatrick, 2004 #12197].
4 Moved here from the Tyrannidae on the authority of Ohlson et al. (2013) [Ohlson, 2013 #14349].
5 Doubtfully diagnosable from brunneifrons, see Fitzpatrick (2004) [Fitzpatrick, 2004 #12197].
6 Doubtfully diagnosable from brunneifrons, see Fitzpatrick (2004) [Fitzpatrick, 2004 #12197].
7 Doubtfully diagnosable from brunneifrons; see Fitzpatrick (2004) [Fitzpatrick, 2004 #12197].
8 For transfer from the Tyrannidae to the Onychorhynchidae; see Ohlson et al. (2013) [Ohlson, 2013 #14349].
9 See Lanyon (1988) [Lanyon, 1988 #2326]. The authorship is not Darwin, contra I.C.Z.N. (1956) [I.C.Z.N., 1956 #6618], but the citation in Traylor (1979) [Traylor, 1979 #3871] is otherwise correct. See Steinheimer et al. (2006) [Steinheimer, 2006 #4439]. The authorship was not the issue on which an Opinion was sought. A correction has been requested from the Commission.
10 For reasons to treat the sulphureipygius group as conspecific with barbatus see Ridgely & Tudor (1994) [Ridgely, 1994 #3272].
11 Frequently treated as a separate species including subspecies aureatus, but see Zimmer (1939) [Zimmer, 1939 #9560] and Ridgely & Tudor (1994) [Ridgely, 1994 #3272] for rationale for continued treatment as conspecific.
12 May merit treatment as a separate species; see Fitzpatrick (2004) [Fitzpatrick, 2004 #12197].
13 Subspecies groups follow A.O.U. (1998) [A.O.U., 1998 #9].
