On the status of 'Prociphilus californicus' (Hemiptera: Aphididae)

摘要

The name "Prociphilus californicus" has been used for aphids that distort leaves of ash (Fraxinus spp.) in the western states. This name is not valid. It is not completely clear which species of Prociphilus the name refers to, but we think it is mostlikely to be Prociphilus americanus (Walker). The relevant literature is reviewed.
