Abstract Four new species of feather mites are described from birds in Canada: Megniniella ratcliffi sp.nov . (Analgidae) and Metanalges holderi sp.nov . (Analgidae) from the Sora, Porzana carolina (Linnaeus) (Gruiformes: Rallidae): Metingrassia pelecani sp.nov . (Xolalgidae) from the American White Pelican, Pelecanus erythrorhynchos Gmelin (Pelecaniformes: Pelecanidae); and Vingrassia cygni sp.nov . (Xolalgidae) from the Tundra Swan, Cygnus columbianus (Ord) (Ànseriformes: Anatidae). The genus Vingrassia is reinstated from its previous synonymy with the genus Ingrassia based on the presence of an enlarged prodorsal shield in both sexes, by the shape of the idiosoma and the interlobar membrane on the lobar apices in the male, and by the shape of the hysteronotal shield and the absence of setae ps2 in the female.
