Acanthiza albiventris hamiltoni Mathews

Acanthiza albiventris hamiltoni Mathews, 1911d: 97 (New South Wales).

Now Acanthiza apicalis apicalis Gould, 1847 . See Schodde and Mason, 1999: 201–203.

LECTOTYPE: AMNH 600550 , unsexed [adult male], collected at Coonalpyn , 35.41S, 139.52E (Times Atlas), 90 Mile Desert, South Australia, Australia, on 17 May 1911, by J.B. Cleland. From the Mathews Collection (no. 8940) via the Rothschild Collection.

COMMENTS: In the original description, Mathews gave New South Wales as the type locality and said that the type was in the ‘‘Coll. G.M. Mathews’’. Later, Mathews (1912a: 349) noted that both the type locality and measurements were given in error. He then gave his catalog number of the type and corrected the measurements, thereby designating the above specimen the lectotype. While the sex is questioned on the original label, someone has added ‘‘s’’, and it is cataloged as a male by Mathews. The lectotype bears both Mathews and Rothschild type labels.

A paralectotype, AMNH 600551, collected at Coonalpyn on the same day, was cataloged by Mathews (no. 8939) as a female, and ‘‘ ♀ ’’ has been added to the label in pencil by a hand unknown.

Mayr (1986b: 435) considered hamiltoni a synonym of A. apicalis albiventris ; however, recent studies by Schodde and Mason (1999: 201–203) included it in A. apicalis apicalis . After comparing the lectotype with specimens of both forms, I find that it is closer to the nominate subspecies.
