G'day Chris,
I guess you can wait for mtDNA analysis and results until Tanami desert freezes 
I strongly beleave that Ray has never made or seen any mtDNA data (other than perhaps the ones from he Gen bank, if any available) for the specific species.
And as you have already seen in Ray's papers from the past, descriptions and diagnoses are always poor and most of them inadequate for people to distinguish the proposed species.
This new paper though has a lot of errors in it (see postings above) and so you might simply ingore it.
Cheers,
Wulf
