Thelaxes suberi (Del Guercio, 1911), an oak-feeding aphid species, is native to Europe, the Mediterranean region, and Southwest Asia, but adventive in South Africa and Florida, USA. The present paper reports the first occurrence of T. suberi in Japan based on the specimens collected in Tokyo in 2017–2019. This adventive species is assumed to have become established in Japan. The colonies of T. suberi were observed on new shoots and leaves of the Japanese native plant, Quercus phillyraeoides and often attended by the Japanese native ants, Lasius japonicus and Pristomyrmex punctatus. These represent newly recorded biological associations for T. suberi, respectively. A Japanese common name is newly proposed for T. suberi: “Korukugashi-mitsu-aburamushi”, meaning cork oak thelaxid.
