1 Paynter (1964) [Paynter, 1964 #2981] treated these birds in a subfamily of a broadly defined Muscicapidae, but A.O.U. (1998) [A.O.U., 1998 #9] placed the subfamily in a broad family Sylviidae.

3 For recognition see Atwood & Lerman (2006) [Atwood, 2006 #12222].
4 For recognition see Atwood & Lerman (2006) [Atwood, 2006 #12222].
5 For recognition see Atwood & Lerman (2006) [Atwood, 2006 #12222].
6 For recognition see Atwood & Lerman (2006) [Atwood, 2006 #12222].
7 Cited by Paynter (1964) [Paynter, 1964 #2981] from volume 29 of the Nouveau Dictionnaire d'Histoire Naturelle but first introduced in volume 24.
8 Subspecies groups derived from Sibley & Monroe (1990) [Sibley, 1990 #3636].
9 Phillips (1991) [Phillips, 1991 #3072] treated rufiventris as a separate species with panamensis as a race.
10 For recognition and comments see Dickerman & Parkes (1997) [Dickerman, 1997 #1353].
11 For correct date see Duncan (1937) [Duncan, 1937 #1442].
12 Subspecies classification based on Phillips (1991) [Phillips, 1991 #3072] but see also Atwood & Lerman (2006) [Atwood, 2006 #12222].
13 Includes mexicana; see Phillips (1991) [Phillips, 1991 #3072].
14 Includes amoenissima and gracilis; see Phillips (1991) [Phillips, 1991 #3072]. But see also Atwood & Lerman (2006) [Atwood, 2006 #12222].
15 Tentatively accepted; see Dickerman & Parkes (1997) [Dickerman, 1997 #1353].
16 For recognition see Atwood & Lerman (2006) [Atwood, 2006 #12222].
17 For recognition see Phillips (1991) [Phillips, 1991 #3072].
18 For treatment as separate species from P. melanura see Atwood (1988) [Atwood, 1988 #15691].
19 Includes margaritae, pontilis and atwoodi Mellink & Rea, 1994 [Mellink, 1994 #2653]; see Zink et al. (2000) [Zink, 2000 #14494]. But see Atwood & Lerman (2006) [Atwood, 2006 #12222] who recognised four subspecies.
20 Date uncertain; adjusted here to agree with that used for Chordeiles gundlachii which was on the preceding page. Quite probable that these are from 1857 but no proof yet found.
21 For treatment as a separate species from P. albiloris; see A.O.U. (1998) [A.O.U., 1998 #9].
22 Subspecies groups follow Atwood & Lerman (2006) [Atwood, 2006 #12222] but some may deserve species rank; see Ridgely & Tudor (1989) [Ridgely, 1989 #3271] and Sibley & Monroe (1990) [Sibley, 1990 #3636].
23 For recognition see Phillips (1991) [Phillips, 1991 #3072].
24 Doubtfully distinct from subspecies superciliaris; Parkes (1979) [Parkes, 1979 #2933].
25 Given as 1851 by Paynter (1964) [Paynter, 1964 #2981] but see Zimmer (1926) [Zimmer, 1926 #4296].
26 Recent authors seem to suggest that birds of the upper Marañón valley may be a distinct species. The origin of this idea appears to be Hellmayr (1934: 493-4 fn) [Hellmayr, 1934 #1945]. Although the name andina may have been given to a female of this taxon it is not the oldest name and there should be no cause to employ a name other than maior.
27 For date correction see Dickinson et al. (2011) [Dickinson, 2011 #13287].
28 For treatment of the three taxa as separate species see Whitney & Alvarez Alonso (2005) [Whitney, 2005 #10112], Atwood & Lerman (2006) [Atwood, 2006 #12222] and Ridgely & Tudor (2009) [Ridgely, 2009 #12008]. Discovery of new taxon attenboroughi suggests re-evaluation is desirable.
29 Proposed as a species but awaiting evaluation by SACC.
30 Subspecies groups follow Sibley & Monroe (1990) [Sibley, 1990 #3636].
