Abstract:
Phoretic deutonymphs (hypopi) of Schwiebea sp. mites were detected during examinations of questing adult and nymphal blacklegged ticks, Ixodes scapularis Say, from vegetation at two woodland sites in northeastern Wisconsin, USA, during May and June, 2014. Collection sites were in Marinette and Oconto Counties, respectively. These hypopi are evidently the first reported from ticks in the Western Hemisphere, and they seem to be most similar morphologically to the putatively Holarctic species Schwiebea nova (Oudemans).
