Family AMPELISCIDAE Costa, 1857

Ampelisca abdita Mills, 1964 (euryhaline, exotic)

Records: Reported from Bolinas Lagoon, Tomales Bay, San Francisco Bay, San Pablo Bay, Suisun Bay, Grizzly Bay, Honker Bay, Sherman Lake, Suisun Bay, Sacramento River (R.) ( Chapman 1988; CDWR database).

Comments: Chapman (1988) predicted a wider Californian range after habitats are better inventoried; an estuarine species ranging naturally from Maine to Gulf of Mexico ( Chapman 1988), A. abdita was probably associated with Atlantic oyster introductions.
