Icterus pectoralis anthonyi Griscom
Icterus pectoralis anthonyi Griscom, 1930: 18 (Finca El Cipres, near Ocos, Pacific coast of Guatemala [error]).
Now Icterus pectoralis guttulatus Lafresnaye, 1844 . See Griscom, 1932: 398–399; Hellmayr, 1937: 145; Blake, 1968: 154–155; Dickerman, 1981; and Dickinson, 2003: 770.
HOLOTYPE: AMNH 398802, adult male, collected at Finca El Cipres, 9 mi from Mazatenango, Pacific slope, at base of Volcan Zumail, Suchitepequez (Griscom, 1932: 417, map), Guatemala, on 28 July 1924, by A.W. Anthony (no. 473). From the Jonathan Dwight Collection (no. 58330).
COMMENTS: Griscom cited the Dwight Collection number of the holotype in the original description and noted that he had 48 specimens (including the type) from Guatemala and three from Nicaragua. Later, Griscom (1932: 398) listed the localities from which his Guatemalan specimens had come, but by that time did not include Nicaragua in the range. Of the 47 Guatemalan paratypes, 35 came to AMNH: Finca El Cipres, AMNH 398801, 398803–398806, 398808–398811, five males, four females, 27 July–1 August 1924 ; Finca El Espino, AMNH 398807, female, 23 July 1926 ; Hacienda California, AMNH 398812–398824, 398826–398828, eight males, eight females, 5–27 June 1926, 25 September– 10 November 1927 ; Ocos, AMNH 398825, 398829, males, 24 October 1927, all by A.W. Anthony ; Pantaleon, AMNH 399361–399366, two males, four females, 22 October–2 November 1919 ; San Felipe, AMNH 399367, male, 4 December 1919, all by Austin Paul Smith. I did not find paratypes AMNH 398816 and 398819 from Hacienda California in the AMNH collection and they were perhaps exchanged later, without the catalog having been marked. The Guatemalan collection was divided with MCZ before it was cataloged at AMNH and the other paratypes are probably there. I also did not find the three Nicaraguan specimens from Leon, Chinandega, and Volcan Viejo ; these were perhaps borrowed from other institutions by Griscom.
Dickerman (1987: 84) called attention to the error in the location of the type locality given in the original description. Griscom (1932: 398) did not correct this in his text, but he did make a correction (Griscom, 1932: 417, map) without calling attention to the earlier error. Mazatenango is at 14.31N, 91.30W (Times atlas).
The subspecies anthonyi was recognized by Hellmayr (1937: 145), synonymized with I. pectoralis pectoralis by Blake (1968: 154– 155), and synonymized with I. pectoralis guttlatus by Dickerman (1981), Dickinson (2003: 770), and Fraga (2011: 766).
