Acanthiza pusilla dundasi Mathews

Acanthiza pusilla dundasi Mathews, 1922a: 431 (Lake Dundas, West Australia).

Now Acanthiza apicalis apicalis Gould, 1847 X A. a. whitlocki North, 1909 . See Mayr, 1986b: 436, and Schodde and Mason, 1999: 201–203.

HOLOTYPE: AMNH 600621 , adult male, collected at Lake Dundas , 32.25S, 121.50E ( Johnstone and Storr, 2004: 509), Western Australia, Australia, on 9 June 1905, by F.L. Whitlock. From the Mathews Collection (no. 5276) via the Rothschild Collection.

COMMENTS: Mathews obtained a single Lake Dundas specimen from WAM according to his catalog, the number of which he did not mention in the description. When he named this form, his syntax was confused: ‘‘I have specimens from Lake Dundas, West Australia, which seems to represent still another race …’’. Whether he had one or more specimens is not clear from this. The above specimen is the only one collected at Lake Dundas that came to AMNH, and I consider it the holotype. It was listed as the type of dundasi by Mayr and Serventy (1938: 264) but had not previously been incorporat- ed in the AMNH type collection. It bears only a Rothschild Collection label, printed ‘‘Ex. coll. G.M. Mathews’’, to which has been added an AMNH type label.

Schodde and Mason (1999: 201–203) indicated (see map) that Lake Dundas specimens were within the zone of intergradation between A. a. apicalis and A. a. whitlocki . The holotype of dundasi appears morphologically somewhat closer to nominate specimens.
