According to me, it is a female of Olethrius. The difference between such Rhemphanini is especially visible in males; however, the third antennomere is much longer in Paroplites.
I do not think: O. laevipennis (described from only one male, here the holotype) is characterised by nearly completely unpunctuated and smooth elytra. This seems to me O. tyrannus (types here) or a hairless specimen of O. scabripennis (holotype here). But I have to check the pictures of the specimens I have observed. The former species has already been recorded as in introduced in Australia.
It seems to be a female of Olethrius tyrannus tyrannus Thomson, 1861. This species should have two sub-triangular almost smooth areas along the median line of the pronotum, but the reflections of this picture make the identification only guessable.
Australia: Olethrius t. tyrannus ♀
