Icterus gularis gigas Griscom

Icterus gularis gigas Griscom, 1930: 13 (Sacapulas, Rio Negro 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 398742, adult male, collected at Sacapulas, Río Negro Valley, central Guatemala, on 4 February 1928, by A.W. Anthony (no. 6513). From the Jonathan Dwight Collection.

COMMENTS: Griscom cited Anthony’s unique field number for the holotype in the original description; it had no Dwight Collection number. Griscom (1932: 396) noted that he had eight males and 10 females, including the type, from Sacapulas. Of the 17 paratypes, there are 11 at AMNH: AMNH 398741, 398743–398752, four males, seven females, 4 February–13 March 1928, by A.W. Anthony. This collection was divided with MCZ before cataloging, and the remaining paratypes may be in that institution .

Hellmayr (1937: 148–149) recognized gigas and considered xerophilus a synonym of it. Both Blake (1968: 156) and Dickinson (2003: 771) followed him. More recently both Dickerman (2007: 38) and Fraga (2011: 765) synonymized gigas and xerophilus with nominate gularis .

Sacapulas is on the Río Negro, 25 mi north of Quiche´, at ca. 15.15N, 91.10W (Griscom, 1932: 421 and map). See Griscom (1932: 11– 15) for a summary of Anthony’s collecting localities.
