Definitely Temognatha limbata, no question. This is the same 'red-margined' form of Temognatha limbata that I have encountered in the Blue Mountains west of Sydney. The metallic green along the elytra suture is modestly variable, and in this specimen the width is within expected parameters. At lower altitudes the pronotal margins are mostly yellow in this species. The punctuations on the pronotum of Temognatha limbata are quite distinctive - as suggested, the punctuations are much finer in Temognatha affinis, which has a flatter body shape including the pronotum and, unlike in Temognatha limbata, Temognatha affinis has elytra that are distinctively bispinose apically. Cheers, Allen M. Sundholm

Did you keep the specimen Stuart ?
The only way to properly identify so many of these species is by comparing all aspects of the specimen by turning it slowly and looking at angles, shapes etc.
I’ve never seen an affinis with a wide green suture combined with the bright red pronotal margins. The punctuation on limbata pronotum is finer and the pronotal shape is different (you have to look at the species side by side from directly above).
I haven’t seen limbata from that far south before however it certainly wouldn’t surprise me.
Cheers

Hi Mark. I just read an excerpt from Saunder's 1868 paper describing (then Stigmodera, now Temognatha) affinis and limbata. He mentions the latter having a more punctate (thorax) pronotum as well as subjective observations around shape of the elytra. Looking at available images, mainly here and on ALA, I am having problems differentiating the two species. Initially I though the more prominent suture on T. limbata was indicative though this is not consistent between images that have been identified. May I ask what feature/s helped you ID this beetle as T. limbata?
