Pachycephalopsis poliosoma idenburgi Rand

Pachycephalopsis poliosoma idenburgi Rand, 1940b: 5 (altitude 1200 meters, 6 km. southwest of Bernhard Camp, Idenburg River, Netherland New Guinea).

Now Pachycephalopsis poliosoma idenburgi Rand, 1940 . See Dickinson, 2003: 520.

HOLOTYPE: AMNH 305666 , adult male, collected 6 km southwest of Bernhard Camp , 1200 m, ca. 03.30S, 139.15E ( Archbold et al., 1942: map 1), Sungai Taritatu (5 Idenburg River), Papua Province, Indonesia, on 2 March 1939, by Richard Archbold, Austin L. Rand, and W.B. Richardson on the 1938– 1939 Archbold Expedition to New Guinea (no. 9800).

COMMENTS: Rand cited the AMNH number of the holotype in the original description and gave measurements of five males and two females. The six paratypes, all from 6 km southwest of Bernhard Camp, 1200 m, Idenburg River, are: males, AMNH 341456 , 23 February 1939, AMNH 341457 , 1 March 1939, and AMNH 341458 , 3 March 1939 ; females, AMNH 341459 , 26 February 1939, AMNH 341460 , 2 March 1939 ; and unsexed [but probably considered a male], AMNH 341461 , 5 March 1939. Of these, AMNH 341458 and 341459 were exchanged to FMNH in the early 1960s, and AMNH 341461 was sent to MZB on 7 May 1957 .

Rand (1942b) reported on all of the birds collected, and Archbold et al. (1942) provid- ed a summary of the 1938–1939 Archbold Expedition, which was also known as the Indisch-Amerikaansche Expeditie naar Nederlandsch Nieuw-Guinea.
