The genus Silpha Linnaeus, 1758 in Silphinae includes 33 species worldwide. This group is flightless and known to feed on invertebrate carcasses from the ground surface. In South Korea, 3 species have been recorded, and S. koreana Cho& Kwon, 1999 is an endemic species, distributed only Mt. Taebaek and Mt. Mindung. Up to date the immature stages of the species has never been studied although the species has significant value as an endemic species. The present study is the very first one ever conducted describing the larval morphological characters of S. koreana along with images of larval stages. Furthermore, we report observations on developmental lengths for each stages of the species.

The Silphidae Latreille, 1806 was reviewed as 26 species of 9 genera from Korea. In this study, we report a new subspecies, Silpha perforata jejuensis ssp. nov, from Is. Jeju and taxonomic revision of the family Silphidae in Korean Peninsula. We provide descriptions, Photograph of morphological and genital structures and a key of Korean species.
