genistae (Latreille, 1804)

Type locality: Europe.

Additional distribution: introduced in USA, California, Oregon, North Carolina, Massachusetts, Washington; Canada, Nova Scotia.

Host plant: Cytisus scoparius .

Remarks: First recorded in North America in the early 1900s, and first recorded in California in 1993 (Wheeler & Hoebeke 2004). Although an accidental introduction, the combination of this species together with another introduced psyllid, Arytainilla spartiophila, may help to control the host plant, which is considered a noxious weed.
