Diomus terminatus
The postcoxal line, length of the 3rd section of the antennae, and more elongate and parallel-sided shape are all typical of Diomus, and D. terminatus is the only one with this pattern.

I think there's been a tendency to throw a lot of scymnines with pale apical margins into the D. terminatus node, but this one I'm sure is indeed D. terminatus.
