The Karner blue butterfly (KBB), Lycaeides melissa samuelis, is a federally
protected taxon whose relationship to the Melissa blue, Lycaeides melissa,
has been a point of contention during the 66 years since the KBB was first
described. Using a large population-genomic dataset and a model of
population divergence with migration, we investigated the relationship
between the KBB and L. melissa, as well as the relationship between L.
melissa and a third taxon, Lycaeides idas. We report that gene flow between
the KBB and L. melissa is low, and comparable to gene flow between L.
melissa and L. idas. Considering this population-genetic evidence, we
conclude that the KBB is a unique evolutionary lineage that should be
recognized as Lycaeides samuelis.

Keywords: conservation genetics; gene flow; Lycaeides melissa samuelis;
population genomics; next-generation sequencing

--- Citing from the Introduction:
"Based on variation in wing pattern and genitalic morphology, the KBB was
described as a subspecies of Lycaeides melissa 66 years ago by Vladimir
Nabokov in 1944, who subsequently and informally revised his opinion to
consider it a distinct species [6,7]."

--- Citing from the Discussion:
"[...] we conclude that the current subspecific designation for the KBB is
inappropriate, and that the KBB should be elevated to Lycaeides samuelis
Nabokov."
