The genus Gonioctena Chevrolat, 1836 is one of the largest genera of the subfamily Chrysomelinae with approximately110 valid species in nine subgenera distributed in the Holarctic and Oriental Regions (Cho 2016). Their larval morphologyis relatively well known, especially in Europe, the Russian Far East and Japan. Larvae of 41 species have been describedbased primarily on the tubercles and chaetotaxy (Kimoto 1962; Medvedev & Zaitzev 1978; Baselga 2008, 2010, etc.).However, their relationship is still incomplete because descriptions of many species are too brief and more than half ofthe species are completely unknown. Here, we redescribe in detail the last instar larva of Gonioctena coreana (Bechyně),G. gracilicornis (Kraatz), G. jacobsoni (Ogloblin & Medvedev) and G. viminalis (Linnaeus) from South Korea. Noteson biology, host plant and ovoviviparity are also provided.
