Boloria andersonii

Similar to B. selene , except probably slightly larger, more underside hind wing median spots yellowish instead of white/silvered (but the one in discal cell white and perhaps silvered); with black spot in middle of discal cell tiny (usually large and prominent in B. selene ); with pale spot at base of discal cell faint, suffused brownish, and not strongly edged on outer edge with black(ish) border. Dorsal side with marginal dark markings smaller and (at least in type specimen male) not connected into a continuous dark marginal border (usually connected in B. selene . This name is something of a mystery, based on a specimen supposed to have been collected in British Columbia, which is not known to have been duplicated since. It is very closely similar to Boloria euphrosyne from Eurasia, and likely does belong to that species [?as a North American subspecies?]. This most likely represents a mislabelling of specimens from Eurasia, but the type specimen is distinct enough from any compared Eurasian material that it's true origin is questionable, and has been debated. This is speculation though, and If truly collected from British Columbia as labelled, this is a lost species. It should be treated as of concern, since the lack of further material implies that it may be quite rare. It is also possible that more collected specimens do exist, but have been misidentified and/or overlooked in collections. Three specimens were supposed to have been originally collected, but only one was seen by Dyer, and that one should still be in the U.S. national collection.
