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.

Location would suggest more likely to be Cadmus (Lachnabothra) distinctus

Cadmus (Lachnabothra) subgenus

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?

Looks like it’s Melobasis pretiosa or at least in that species group
