Caenocara oculatum (Say), male
Moved from Caenocara blanchardi. Revised ID from voucher.

I compared genitalia of this vs the earlier one I called blanchardi (779775) and they are distinctly different. I found a somewhat obscure paper on Palearctic Caenocara (Espanol 1977) which illustrates a few of our species. The genitalia of this specimen matches Espanol's illustration of C. oculatum very well. The other one I will still tentatively call C. blanchardi.
