Further genomic sequencing of butterflies by our research group expanding
the coverage of species and specimens from different localities, coupled
with genome-scale phylogenetic analysis and complemented by phenotypic
considerations, suggests a number of changes to the names of butterflies,
mostly those recorded from the United States and Canada. Here, we present
evidence to support these changes. The changes are intended to make
butterfly classification more internally consistent at the genus, subgenus
and species levels. I.e., considering all available evidence, we attempt
to assign similar taxonomic ranks to the clades of comparable genetic
divergence, which on average is correlated with the age of phylogenetic
groups estimated from trees. For species, we use criteria devised by
genomic analysis of the genetic divergence across suture zones and
comparison of sympatric populations of closely related species. As a
result, we resurrect 4 genera and 1 subgenus from subgeneric status or
synonymy, change the rank of 8 currently used genera to subgenus,
synonymize 7 genus-group names, summarize evidence to support 19 taxa as
species instead of subspecies and 1 taxon as subspecies instead of
species, along with a number of additional changes. Less...
