This species is still problematic.
I'm not satisfied with Gordon's treatment of this species, personally. In photos like this, it is hard to distinguish the traits of the head, as Chilocorus normally have silvery hairs that may give the appearance of the "punctured" look described in C. kuwanae.

It would be wonderful to have confirmed specimens of all involved species side-by-side.

I'll see if I can get a few specimens this year.

Thanks Tim
I wonder how many of the other pictures are this same species.

only one
I did a look prior to posting on yours and from what I can see, yours is the only one so far. I was surprised.

C. kuwanae
Tom, I'm fairly certain this one is actually C. kuwanae, and import from Japan/Korea. Spot is "at or behind middle", and Gordon states further that "the head is dull, strongly alutaceous with punctures extremely close together", which I think fortunately we can see from your (atypical) lateral view. The more rectangular shape of the spot is also characteristic. See here. Apparently the species has been introduced much wider since Gordon's writing.

I'll update the distro info on the Genus page. And these are a great set of images to start another new species for BugGuide :)
