On Stethorus
the prosternum projects forward. I can't really tell from your image if that's the case, but if you have the specimen you might be able to confirm/deny that.

Size estimate seems large for Stethorus, but...

I'm going to add a new ventral image concentrating on the prosternum. I'm not sure what you mean by projects forward so hopefully the new image will define for you. Also re-looked at the size, it looks correct but might be just a little less, 2.0 mm at less.. Let me know if this works, and thanks.

as for "projects forward"
Each person words it differently, but here is how Gordon describes it: "Anterior margin of prosternum lobed, at least partially concealing mouthparts". Basically Stethorus have a little bump on the front of the prosternum, while Scymnus and co. don't.

The introduced Stethorus is listed as a maximum of 2.0mm. The others are not recorded greater than 1.4mm.

In any case as long as I'm not going insane the prosternum does not have the projection, which places it to Scymnus sp.

Thanks James..
For your insight, upon looking under higher resolution and understanding what you are referring to about the prosternum I would concur it does not have the projection. I'll move specimen to Scymnus tentatively and see if anyone objects... thanks again.

Stethorus comes to mind
