The family Anamorphidae Strohecker is a beetle family that comprises about 170 species worldwide. This family was traditionally considered as a subfamily of the family Endomychidae Leach because of their similar appearance, but a phylogenetic study revealed it is a separate family. The adults of this family can be distinguished from endomychid species by possessing a tentorium with corpotentorium and separated anterior arms, mesocoxal cavities being broadly closed by meso- and metaventrites, and others. Although more than 20 species have been reported in East Asia, this family has never been reported in Korea. In this study, the family Anamorphidae Strohecker and its 5 species of 3 genera, Bystodes kidoi Sasaji, Bystodes sp.1, Bystodes sp.2, Dexialia hiranoi Narukawa, Idiophyes sp., are reported for the first time in Korea. Illustrations of habitus and diagnostic characters of each species are provided.
