    Aculus brewerianae n.sp., Keiferella brewerianae n.sp. and Nalepella brewerianae n.sp. were found in 2003 on Siskiyou spruce (Picea breweriana S.Wats). Nalepella brewerianae n.sp. prefers upper side of needles less inferior side or branches as a vagrant. Aculus brewerianae n.sp. and Keiferella brewerianae n.sp. settle on inferior side of needles.
