Icterus gularis xerophilus Griscom

Icterus gularis xerophilus Griscom, 1930: 14 (Progreso, Motagua River Valley, central Guatemala).

Now Icterus gularis gularis (Wagler, 1829) . See Griscom, 1932: 396; Hellmayr, 1937: 148–149; Blake, 1968: 156; Dickinson, 2003: 771; Dickerman, 2007: 38; and Fraga, 2011: 765.

HOLOTYPE: AMNH 398756 , adult male, collected at Progreso, 17.18N, 90.08W (Times atlas), Motagua River Valley , central

Guatemala, on 5 July 1924, by A.W. Anthony (no. 287). From the Jonathan Dwight Collection (no. 58303).

COMMENTS: Griscom cited the Dwight Collection number in the original description and said that he had 21 specimens, including the type, from Progreso ; Griscom (1932: 396) noted that there were 16 males and five females. Of the 20 paratypes, the following 14 are cataloged in AMNH: AMNH 398753– 398755 , 398757–398767 , eight males, two immature males, four females. I did not find AMNH 398762 in the collection and it is possible that it has been exchanged to another institution without the catalog having been marked. Part of this collection went to MCZ before cataloging and the remaining paratypes may be in that institution .

Hellmayr (1937: 148) recognized I. gularis gigas and synonymized xerophilus with it. Blake (1968: 156) and Dickinson (2003: 771) accepted that. More recently, Dickerman (2007: 38) synonymized both xerophilus and gigas with nominate gularis , and Fraga (2011: 765) agreed. Dickerman (2007: 38) incorrectly gave the original citation to I. g. xerophilus as Griscom (1930: 4); the description was on page 14.
