OK, I agree, not similar to that set museum specimen. More similarities with these live specimens I think: https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/d379b9a9-1daf-4ec2-a4b5-5d0434bf5c34#gallery But also see this recent record from Donald Hobern on Black Mountain ACT?: https://twitter.com/dhobern/status/1560272526516768768?s=20&t=aivjBtipbE7CNKdJH0yAQg and see in iNaturalist. Not exactly the same, but similar. I'm just asking the question. Hyperxena (genus) seems to be very poorly known.
