Synonyms and other taxonomic changes
In 1996, Lafontaine and Mikkola described the Nearctic Pyrrhia adela as a new species, distinguishing it from the Old World Pyrrhia umbra described in 1766 by Hufnagel. Prior to 1996, all North American records of "P. umbra" were misidentifcations of P. adela. In other words, P. umbra is not a synonym of P. adela; both are distinct species.
3 species in North America
8 additional species in the Old World
P. adela - eastern North America: Newfoundland to Florida, west to Texas, north to Saskatchewan
P. exprimens - across southern Canada and northern United States, south in the east to North Carolina, south in the west to California
