Abstract. The Spanish slug Arion vulgaris, an actively spreading invasive species worldwide, has been recorded for the fi rst time on Sakhalin Island. This is the second documented occurrence of this aggressive alien species in the Russian Far East. The detection of A. vulgaris in Vladivostok, Nakhodka, and Yuzhno- Sakhalinsk, along with the confi guration of the main transport routes, suggests its spread from the Central Federal District via rail and air transport. The progression of the A. vulgaris invasion in Russia and potential control measures are discussed.
