Hi Michael. I recall seeing the ID confirmed by Allen s somewhere today but couldn't find it again? A check of available reference material pretty much confirms it and being no 'temog' expert that's the best I can do. Our jewel beetle moderator Mark Hanlon is as good as they get on this genus, his opinion would be definitive I reckon.
Yes definitely Temognatha gemmelli. The pronotum is more finely punctured than T. suturalis which it can be mustaken with. The record is a fair way south and might be close to its southern limit of distribution. The species stronghold is northern NSW however I have caught it up as far as Rockhampton in wetter sclerophyll habitats
I have taken this further south near Landsdowne, in the Coopernook area, which is to the NE of Taree. There is a photo that Dr Geoff Williams took of a live one sitting on Leptospermum flowers (Fig. 477) on page 134 of the book 'Australian Jewel Beetles. An Introduction to the Buprestidae' that Geoff and I co-authored with Kevin Mitchell, published by CSIRO Publishing in March 2024. Cheers, Allen M. Sundholm.
