Ips subelongatus, known generally as larch bark beetle or oblong bark beetle, is a species of typical bark beetle in the family Curculionidae. It is considered near indistinguishable from Ips cembrae except for the species of tree it chooses as a host and through DNA analysis. The species of tree it dwells in are Larix sibirica, Larix gmelinii, Larix leptolepis and Larix gmelinii var. olgensis. The beetle is found in the Asian part of Russia, China (Heilongjiang, Jilin and Liaoning provinces), Japan (Hokkaido and Honshu), the Korean peninsula and Mongolia.[1]
