I think because the ridges on this beetles back are uninterupted that it is A. pustulosum rather than A. porcatum where the ridges are interrupted.

Thanks, Michael. Adelium pustulosum appears to have a dark bronze body colour. This individual does not fit the description. From your comment, it does not sound like Adelium porcatum. I thought it was Adelium porcatum since the images on CNM looked most similar. We need an expert opinion on this.

The sculpture on the surface of the pronotum discounts A. pustulosum. I'll call it A. porcatum for now, but I'll check the image against ANIC material when I can.

Thanks Kim much appreciated

Based on specimens in ANIC (CSIRO), this is most likely to be Adelium tenebroides Erichson (recorded from Tas, Vic, and Batlow NSW), although Adelium capitatum Lea (recorded from interior of NSW and Qld) is also like it.
