Diomus xanthaspis (Mulsant), male
Moved from Dusky Lady Beetles. ID'd from specimen, now a photo-voucher. Thanks John.

Tiny thing at 1.5 mm. I had assumed Scymnus as well, but became confused as the male genitalia looked nothing like kansanus or cervicalis. Reexamination showed this was rather Diomus.

This is at about the northern extent of the range for D. xanthaspis. Previous northern limits were Maryland and Indiana. Possibly a new state record.

I don't think I saved the specimen linked below
Safe to assume it's the same or should we move it to a higher level?


I'm pretty sure it must be the same
Looks identical to me

Scymnus kansanus or cervicalis
A ventral image is required for identification between the two species. Do you have, or could you take, a photo of the underside?

I caught another one
and posted it with a ventral shot, hopefully showing what you need to see.

I have the specimen in alcohol in a vial
with a bunch of other specimens that I will be sending to Brad Barnd. If I catch another I'll be sure to take a ventral shot. Thanks Abigail!

Moved from Beetles.
