~45mm long

I'm not confident of my id. Hopefully I've at least got the genus right. There is the local Pachymorpha spinosa, but this looks quite different to me.

Location is wrong for the species; as is the colour.
But the antennae length, posterior, etc, seem to match.

Thought it was a juvenile Hyrtacus tuberculatus, due to the "Dog-ears" but don't believe it is.

NB: Not on Ellura, but Adelaide Hills.

This is one of a number of large River she-oaks that we have on the fresh-water river bank. This is the largest - at least 35m tall and 1.5m diameter about a metre up from the base which is wider because of the roots. Reckoned by various people from CSIRO and Biology School teachers to be at least 500 years old while a neighbouring Cas. Cun. tree is thought to be 200 years old. It is probably flowering as the neighbouring one has some flowers and small brown woody cones about 1cm long. 'Finer' leaves than on the black she-oaks.
