Zhang et al. 2022 used genomic sequencing to determine that North American Boloria myrina is a full species distinct from Eurasian B. selene. North American subspecies of B. selene are now treated as subspecies of B. myrina. The Pelham catalog (2023) and Moth Photographers Group adopted these changes.
