Yes, I confirm that this is definitely Temognatha sanguiniventris. Stuart, you had it right. Mark, it sounds like you may have specimens of Temognatha sanguiniventris in your collection that have been misidentified as Temognatha thoracica. I agree though that this it is not Temognatha sanguinipenns which is very different indeed - that's another story. Anyway, compared to Temognatha thoracica, (a) the specimen in the photos in this post has shorter elytra, is flatter and is differently shaped, when looking from above, to Temognatha thoracica; (b) has distinctly explanate margins to the pronotum whereas in Temognatha thoracica the pronotal margins are more rounded, and (c) displays the graduated marginal elytral colouring that is often seen in Temognatha sanguiniventris but is not seen in Temognatha thoracica. I have encountered both species and others and have good series of specimens of both Temognatha thoracica and Temognatha sanguiniventris and readily relate that some curated specimens of Temognatha thoracica remind one of Temognatha sanguiniventris, but never the other way around. Their body shapes, pronotal margin shapes, and colour shadings, all differ. Once you 'get your eye in' with finding specimens of both species in what little is left of the wild they become quite easy to determine to species, and consequently likewise with curated specimens. Cheers, Allen M. Sundholm.

This is 100% a Temognatha thoracica. Definitely not T. sanguinipennis which is a narrower species with a different apical mark.
I have compared the photos with my collection and it matches thoracica exactly.
