Recent collecting on Sakhalin and the Kuril Islands, during joint U.S., Russian, and Japanese surveys known as the International Kuril and Sakhalin Island Projects, has resulted in range extensions for 10 species in the braconid subfamily Agathidinae and 17 new taxon records for islands in the Kuril chain, Sakhalin, and Moneron. In addition to a check list of the 19 species of Agathidinae presently known to occur on Sakhalin and the Kuril Islands, a generic key and updated keys to the species of Agathis Latreille, 1804, Bassus Fabricius, 1804, and Coccygidium Saussure, 1892 are provided for the region at large (i.e., Japan and the Russian Far East). Of the Agathidinae occurring on Sakhalin and Kuril Islands, most are widespread throughout the Russian Far East and Japan. In the Kurils, species are largely restricted to the southern portion of the archipelago.
