Lepidoptera Taxonomy

I was going to move a photo someone posted to the guide. It used to be called Rosner's Hairstreak (Callophrys rosneri), but is now called Cedar Hairstreak (Mitouri rosneri). I didn't if I should make a new genus, Mitouri, or if I should just put it as Rosner's and make the species rosneri under Callophrys. Here is the photo I am going to move.

Swallowtail butterflies
Can someone comment on the new use of Pterourus instead of Papilio for the genus in swallowtails?

Changed title and moved to this forum
Thanks to the Balaban's for the suggestion.

Someone should be able to tell you what authority we are using for Butterfly taxonomy. We didn't find anything identified on the Taxonomy Forum. Just wanted to suggest that whatever is recommended, we would think you should move both images, the one in ID Req and the one in Callophrys. Thanks.

I didn't know there was a taxonomy forum. I should have posted it there. Anyway, I guess I will put both photos under Rosner's Hairstreak, since the correct genus already exists.

Butterfly taxonomy
I've been organizing the butterflies according to the taxonomy in Opler and Warren's butterfly list for North America. You can download a copy (an 83 page PDF) from here. Of course taxonomy is always changing, especially in a group such as the butterflies, but that list is probably the best available. It keeps all of the subdivisions of Callophrys s.l. as subgenera rather than genera. It also treats C. rosneri as part of C. nelsoni, although some other sources (eg. the Butterflies of Canada) treat it as a distinct species. There are many taxonomic problems in this genus, especially in the west.
