Orgyia papuana also occurs – http://www.ento.csiro.au/aicn/name_s/b_2971.htm

(see http://www.papua-insects.nl/insect%20orders/Lepidoptera/Lymantriidae/Lymantriidae%20list.htm for a checklist of Papuan tussock moths). This has a broader forewing medial band, notably on the lower part (from the dorsum to the cell).

Finally, note that Lymantriidae (and Arctiidae) are now considered to be subfamilies of Noctuidae!! (Lafontaine & Fibiger 2006 – see http://users.utu.fi/rezzah/quadrifine_noctuidae.html and scroll to the bottom for more details). Major shake up, though there are further investigations on-going and more moves are distinctly possible.
