AbstractDiplolepis triforma n. sp. is described and distinguished from other members of the genus. Diagnoses are given for closely related species: D. ashmeadi (Beut.), D. inconspicuis Dailey and Campbell, D. nodulosa (Beut.), and D. verna (O.S.). Lectotypes are designated for D. ashmeadi, D. nodulosa, and D. verna. The genus Diplolepis Fourcroy is briefly reviewed. The biology and ecology of D. triforma and its gall are described. Diplolepis triforma induces a multichambered, polymorphic stem gall on Rosa acicularis and is distributed throughout central and western Canada. The form of the gall depends on the developmental condition of the host plant at the time of oviposition.
