A comprehensive checklist identifying host plants of phytophagous insects are essential in protecting forest ecosystems from major insect pests. We investigated host plants of Callipogon (Eoxenus) relictus Semenov (Coleoptera: Cerambycidae: Prioninae), an insect categorized as a natural monument in South Korea. Field surveys in Gwangneung forest led us to newly recognize the oriental white oak, Quercus aliena Blume (Fagaceae), as a host plant of C. (E.) relictus. Based on this result and a literature search, we provide an updated list of host plants of C. (E.) relictus in the present study. In addition, we also discussed about microorganisms (mushrooms) and habitats in Gwangneung forest (South Korea) and Ussurisky Nature Reserve (Russia) that are relevant to C. (E.) relictus. [Display omitted] •Quercus aliena is a novel host of phytophagous Callipogon relictus in South Korea.•In total, C. relictus now has 17 hosts, all deciduous broad-leaved trees.•C. relictus is associated with white and brown lignicolous fungi.•Habitat surveys should expand to account for wider-than-believed host range.
