Additional records of Aedes riversi Bohart and Ingram from temperate Japan are presented. All new records are from islands north or west of Kyushu except one from the southeast coast of the Kyushu main island. Aedes riversi is widely distributed on the satellite islands north of Kyushu, though its known habitats are confined to lowland-type natural forests of evergreen broad-leaf trees (lowland-type lucidophyllous forests). The origin and present status of Ae. riversi populations on the satellite islands of north Kyushu are discussed in the context of habitat characteristics, human activities and interaction with Ae. albopictus (Skuse) and Ae. flavopictus Yamada.
