• Type identity and synonomy discussed by Mason IJ. 1982. "The identity of certain early Australian types referred to the Cuculidae." BBOC 102(3):99-106.
• Mason gives the synonomy as follows (abbreviations and citational orthography by my convention):

  Cacomantis flabelliformis flabelliformis (Latham).
  Cuculus flabelliformis Latham, 1801 Suppl.ind.orn. p.xxx (Sydney area,
  	New South Wales). 
  Sylvia rubricata*  Latham, 1801 Suppl.ind.orn. p.lv (Sydney area,
  	New South Wales). 
  Cuculus rufulus Vieillot 1817 Nouv.Dict.Hist.Nat. 8 p.234 (Nouvelle-
  	Hollande==Australia).
  Cuculus prionurus Lichtenstein 1823 Verz.Doubl.Zool.Mus.Berlin p.9
  	(New South Wales).
  Cuculus cineraceus Vigors & Horsfield 1827 Trans.Linn.Soc.London(1)

  Cuculus rubricatus athertoni Mathews 1912 AustralAv.Rec. 1 p.11

  	(Albany, Western Australia).
  Cacomantis rubricatus eyrei Mathews 1918 BirdsAustr.[Mathews] 7 p.320

  *"Now that Sylvia rubricata is placed within the synonomy of the Fan-tailed
  Cucukoo the next available name for the Rock Warbler is Origma solitaria
  (Lewin) (see also Mathews 1922 [Birds of Australia Vol.9])."
