I asked Axel Kallies whether the white thorax specimens were a different species, and received the following "that is entirely possible; Trismelasmos donovani is either very variable or contains a series of species. Certainly there are a few species in the genus that are not described. But at this stage I find the group impossible to solve without molecular data. This specimens is certainly a bit unusual."

Trismelasmos (genus)

T. donovani seems to have a variable colour to the thorax, ranging from white with a black V, to grey with black markings. Dimorphic?

Zeuzera quieta versus Orientozeuzera quieta
I have looked at the reference used in the Wikipedia stub you cited. Found via a search at
https://www.zobodat.at/pdf/Neue-Entomologische-Nachrichten_66_0001-0129.pdf
Yes this proposes a new genus Orientozeuzera (p. 58) and moves some Zeuzera sp to this new genus (comb. nov.). It also proposes a number of new species (spec. nov.) that are assigned to the new genus. However, in the case of Orientozeuzera quieta the entry reads as follows:-

" ? Orientozeuzera quieta Turner, 1932
Zeuzera quieta Turner, 1932, Trans. Proc. Roy. Soc. South Australia 56: 194.
LT: North-West Australia: Wyndham. Type material (holotype by monotypy) in Museum of Economic Entomology, Canberra. Distribution: Australia (Queensland, NW Australia) (Turner, 1945)." (p.59)

There is a "?" at the start of the entry and it is not labelled "comb. nov." so I take it the author is unsure about the new placement of this species.
I expect there will be no changes on AFD/ALA any time soon.

See https://en.wikipedia.org/wiki/Orientozeuzera_quieta
Yakovlev, apparently, found evidence that it better fitted Orientozeuzera.
Anyway, all will perhaps be revealed when/if AFD comes good.
Meanwhile we flounder.

I proposed Zeuzera quieta as per my comment yesterday with the 2 references. Both these references called it Zeuzera quieta. I did not encounter the other name. I don't know how my suggested name changed. Is it related to the evaporating histories? I did add the synonym of Orientozeuzera quieta to the species record of Zeuzera quieta.
