This may well be Aulacocyclus edentulus, but I can't see the critical features well enough to be sure. Pharochilus is another option - see https://southernforestlife.net/happenings/2018/8/19/beetle-biodiversity .

Thanks Kim for confirming and identifying the insects I have uploaded recently. Unfortunately I did not take some really close images of this passalid beetle, but if it is useful I have added a heavily cropped image of the thorax and head. Details may have been clearer if the beetle hadn't walked through some cobwebs.
