Taxonomic Swap 124231 (Committed on 03-09-2023)

Zhang et al. 2020 used genomic analysis to determine that Speyeria is a subgenus of Argynnis. The Pelham catalog and Moth Photographers Group adopted this change.

This taxon swap will accomplish the updating of the species and subspecies names. It will be followed by moving the species to the subgenus Speyeria.

I have reservations about this taxon swap, which seems to be premature. Please see comments in the forum.

@ellenjones This change has been made in Pelham's catalog
Butterflies of America
and many web sites, including the Butterflies of North Carolina

Good to see it here too.

Has this been done at BAMONA and NABA and Lepidopterists' Society yet?

Here are my comments from the forum page, which has now been closed.

Has this change been adopted by Butterflies and Moths of North America? Has the Integrated Taxonomic Information System incorporated this change?

Yes, I read your justification ( 15 ) and am underwhelmed. One of the sources you cite is a moth photographers group. If the Zhang et al material is so compelling, it would seem that BAMONA and ITIS would have adopted the change. Have they?

@treichard Has the paragraph you cite ( 2 ) been peer reviewed? The para says that “our genomic studies” (not specified) support the view that Speyeria should be considered a subgenus within Argynnis, thus supporting Simonson’s 2006 “suggestion.” Have other specialists weighed in on this “suggestion”? If not, why doesn’t iNaturalist wait until this change is widely accepted, instead of being a “suggestion” that one research group supports? Their data may indeed be compelling. If so, sources like BAMONA and ITIS will adopt this “suggestion,” and at that point it would be appropriate for iNaturalist to do likewise.

Let's have one discussion about this instead of three, and have it here:
