Chlorospingus ophthalmicus dwighti Underdown

Chlorospingus ophthalmicus dwighti Underdown, 1931: 612 (Finca Sepur, Vera Paz, Guatemala).

Now Chlorospingus ophthalmicus dwighti Underdown, 1931 . See Hellmayr, 1936: 399–400, Isler and Isler, 1999: 60–63, Dickinson, 2003: 817, Sánchez-González et al., 2007, and Wier et al., 2008.

HOLOTYPE: AMNH 294658 , adult male, collected at Finca Sepur , ca. 10 mi north of Sepacuite, 15.29N, 89.52W ( Selander and Vaurie, 1962), Alta Verapaz, Guatemala, on 4 January 1926, by Alfred W. Anthony (no. 2997). From the Jonathan Dwight Collection (no. 61693).

COMMENTS: Prior to Underdown’s publication of C. o. dwighti, Hellmayr had examined the type of Bonaparte’s Poospiza olivacea , the type locality of which was suspect. As Chlorospingus olivacea , the name had been applied to eastern Guatemalan birds, but Hellmayr found that this immature type specimen most closely matched nominate C. ophthalmicus , thus leaving the eastern Guatemalan birds without a name. Underdown supplied this when he named dwighti.

In the original description, Underdown designated as the holotype AMNH 294658 , but did not mention any other specimens. In his revision of C. ophthalmicus , he ( Underdown, 1932: 643) listed the material he examined. It is difficult to recognize which specimens he borrowed to describe dwighti. The following are paratypes: AMNH 398484 (Anthony no. 5382, Dwight no. 63101), female, Barrillos, 21 March 1927 ; AMNH 398485 (5585, 63106), male, Nebaj, 29 April 1927 ; AMNH 398488 (5231, 63102), female, San Mateo, 15 February 1927 ; AMNH 398489 (5235, 63103), male, San Mateo, 16 February 1927. Underdown did not list the female from Finca Sepur , and apparently did not have it in hand. Two males and two females from Finca Sepacuite were examined, but I have found no way to tell which specimens these were from among the many in AMNH from that locality, nor was it possible to identify the seven ‘‘ Guatemala (Vera Paz skins with no data)’’ that he saw. He also listed a male and a female from Tumbala, Chiapas, which do not appear to be in AMNH .

Sánchez-González et al. (2007) recommended considering dwighti a full species. The type of this subspecies was listed by Dickerman (1987b: 79), but the AMNH number was incorrectly given as 492658; the correct number is AMNH 294658.
