Nymphs and adults of Cerophagus nearcticus n. sp. are described from the nest of Bombus terricola occidentalis in California and phoretic associations with B. impatiens in Michigan and New York. On the basis of adult morphology, the genus Cerophagopsis is removed from synonymy with Cerophagus and retained in the family Acaridae, while Cerophagus is transferred to the family Gaudiellidae. The genus Rhypoglyphus is considered a junior subjec­tive synonym of Cerophagopsis. The genera of Gaudiellidae are noted and the genus Trigonacoptes is considered a junior subjective synonym of Gaudiella.
