Additional Records of a Non-native Species, Thelaxes suberi (Hemiptera: Aphididae: Thelaxinae) on Its Distribution, Host Plant, and Attending Ant in Japan, with Notes on Its Nymphal Morphology and Phenotypic Plasticity

抄録

Thelaxes suberi, a non-native species in Japan, is newly recorded from Kanagawa and Osaka Prefectures. The latter represents the first record in Kinki district. Quercus acutissima and Crematogaster matsumurai are recorded for the first time as its host plant and attending ant in Japan and world. The paper also briefly describes its nymphal morphology and provides an identification guide of T. suberi and Kurisakia querciphila the most confusing species in Japan. Moreover, we report the seasonal effect on the phenotypic plasticity, especially body length, of adult T. suberi.
