Euphyes vestris osceola (Lintner, 1878) is a valid subspecies

Currently placed as a junior subjective synonym of Euphyes vestris vestris (Boisduval, 1852) (type locality in the USA: California, Plumas Co.), Pamphila osceola Lintner, 1878 (type locality in the USA: California, Mendocino Co.) shows genetic differentiation from it and forms a distinct clade in genomic trees ( Fig. 52). Due to this genetic differentiation, coastal north-central California populations of E. vestris are best treated as a separate subspecies, even more distant genetically from the nominotypical subspecies than southern Californian Euphyes vestris harbisoni J. Brown & McGuire, 1983 (type locality in USA: California, San Diego Co.) ( Fig. 52). Therefore, in agreement with Emmel et al. (1998), we consider Euphyes vestris osceola (Lintner, 1878) , stat. rev. to be a valid subspecies.
