Hemithraupis flavicollis aurigularis Cherrie, 1916b: 389 (Suapure, Venezuela).

Now Hemithraupis flavicollis aurigularis Cherrie, 1916. See Hellmayr, 1936: 382–383, Isler and Isler, 1999: 93–95, and Dickinson, 2003: 815.

HOLOTYPE: AMNH 75922, adult male, collected at Suapure, 07.14N, 65.10W (Paynter, 1982), lower Rio Caura, Bolívar, Venezuela, on 9 September 1901, by S.M. Klages.

COMMENTS: Cherrie cited the AMNH number of the holotype in the original description and described both males and females without saying how many specimens he examined but noted that in addition to the Suapure specimens, he had a specimen of his new form from the Cunucunuma River, also in AMNH. He included in aurigularis Caura River specimens in the Rothschild Collection that had been reported on by Hellmayr (1907b: 351). Those specimens are now in AMNH. Paratypes, all from Venezuela, are: Suapure, AMNH 75661, male, 20 November 1900; AMNH 75662, female, 9 February 1901; AMNH 75923, one male?, 9 September 1901, by S.M. Klages. Boca de Sina, Cunucunuma River, Upper Orinoco, AMNH 121209, male, 19 March 1913, by Miller and Iglseder. Suapure, AMNH 511178, female, 29 April 1899; AMNH 511179, female, 12 October 1900; AMNH 511180, male, 11 April 1900; AMNH 511181, male, 12 April 1899; AMNH 511182, male, 29 April 1899, (by Klages). Nicare, Caura River, AMNH 511183, male, AMNH 511184, male, AMNH 511185, ‘‘female’’ [male plumage], all 22 January 1901, by E. Andre´.

Hellmayr (1907b: 351), working in the Rothschild Collection, had given measurements for two females and five males, and had probably omitted the specimen sexed as a female but in male plumage. Berlepsch and Hartert (1902: 22), in their report on Orinoco birds, listed the specimens collected by Klages and by Andre´; a fourth male specimen collected by André was evidently exchanged away by Rothschild before Hellmayr studied these birds.
