An annotated list of 24 species of Orthoptera from 22 genera and 8 families found in the Kurilsky Nature Reserve (Kuhashir Island) and the Malye Kurily Wildlife Refuge (Lesser Kuril Ridge) is presented for the fi rst time. The Kurilsky Nature Reserve consists of Southern and Northern sectors. The orthopteran fauna of the Southern sector is the most diverse, with 22 species inhabiting this area, most of which are found within the caldera of Golovnin Volcano. Only five species Orthoptera species were recorded on the slopes of Tyatya Volcano and the Dokuchaev Ridge within the Northern sector, but the fauna’s uniqueness is enhanced by the presence of the Kuril endemic Alpinanoplophilus kurilensis from the subfamily Anoplophilinae. In the Malye Kurily Wildlife Refuge on Shikotan Island, fi ve species were detected, one of which also occurs on Yuri Island, while no orthopterans were found on Polonsky, Zeleny, Tanfi liev, Anuchin, Demin and Oskolki islands. It is demonstrated that the Kurilsky Nature Reserve and the Malye Kurily Wildlife Refuge represent unique protected areas in Russia.
