Phylidorea crane flies(Diptera: Limoniidae) of Korea

This study is based on crane fly specimens collected during more than 80 years, from 1937 through 2019, and are in collections maintained at the United States National Museum, Smithsonian Institution, Washington DC, USA; at Korea University collection, Seoul, South Korea, and the National Institute of Biological Resources, Incheon, South Korea. Three species belonging to genus Phylidorea Bigot, 1854 originally were described from North Korea and in total four species were known from the Peninsula. Phylidorea (Phylidorea) multidentata (Alexander, 1938) is a Korean endemic. We are adding P. (P.) melanommata (Alexander, 1921) to the list of Korean species, which was previously recorded from Japan and Far East of Russia. We present general information on genus and subgenera, redescriptions of species based on Korean specimens, illustrations of both sexes, elevation range, period of activity, habitat information, general distribution, and a distribution map for the Korean Peninsula (including North Korea) for each species.
