Three ptiliid species (Coleoptera: Ptiliidae) new to Korea

Abstract

The family Ptiliidae is one of the poorly known groups of beetles. Approximately 70 species are currently recorded in Japan and Russian Far East. In Korea, however, taxonomic studies involving ptiliid beetles were started with the recording of three species in 2020–2021. In this study, three additional ptiliid species, Baeocrara japonica, Cissidium elongatum, and Ptinella mekura are recorded in Korea for the first time. Illustrations of habitus, diagnostic characteristics, a distribution map, and a key to the Korean ptiliid species are provided.
