An inquiline species of Tamalia co-occurring with Tamalia coweni (Homoptera: Aphididae)

摘要

Tamalia inquilinus Miller, NEW SPECIES, is described from California and is compared with its frequent gall-inducing associate, Tamalia coweni (Cockerell). A key is presented for distinguishing the known species of Tamalia. It is suggested that T. inquilinus may be entirely dependent on T. coweni for the induction of galls that the two species co-occupy.
