Now Philemon citreogularis citreogularis (Gould, 1837) . See Salomonsen, 1967: 404 , Schodde and Mason, 1999: 287–288 , Christidis and Boles, 2008: 185–191, and Higgins et al., 2008: 684– 685 . HOLOTYPE : AMNH 696805 , adult male, collected in South Australia , no date. From the Mathews Collection (no. 4174) via the Rothschild Collection. COMMENTS: In the original description, Mathews gave his catalog number of the holotype and the range of didimus as ‘‘ South Australia , Victoria .’’ Mathews obtained the holotype from the Rothschild Collection and cataloged it on 20 February 1910 . The original Rothschild label has been removed, and it is interesting that no Rothschild label, printed ‘‘Ex. coll. G.M. Mathews,’’ was ever attached to it when it went back to the Rothschild Collection. It bears the original label with minimal data and Mathews and Rothschild type labels. This was apparently the only specimen from South Australia or Victoria that Mathews had. The species is extremely rare and localized in South Australia , occurring only in the riverine woodlands of the Murray River upstream from Renmark (R. Schodde, personal commun.).
