Abstract. We describe the new speciesSaemiindssoniaboschirecentlycollectedfrom
Least Auklets (Aethia piisilla (Pallas)) in Alaska and review the 11 names previously
applied toSaemuiulssoniaTimmermann speciesfrom alcids. Saetnundssoniaprocax(Kel-
logg and Chapman) is relegated to a new junior synonym of 5. giylle (O. Fabricius).
along with the previously recognizedjuniorsynonym 5. inegacepludns (Denny).The nine
previously described valid species are redescribed and illustrated and four new host re-
cords are documented from alcids. Finally, a key is provided for the identification ofthe
ten recognized species ofalcid Saemiindssonia.
