Adelphomyia crane flies (Diptera, Limoniidae) of Korea with identification key for all Palaearctic species

Abstract

Limnophilinae crane flies belonging to the genus Adelphomyia Bergroth, 1891 of the Korean Peninsula were studied starting from 1937, but only one species A. macrotrichiata (Alexander, 1923) has been recorded from North Korea so far. The genus was unknown from South Korea. Four species were found during our studies on the Peninsula, one of them from Jeju Island described as new, Adelphomyia jejuana Podenas, sp. nov. Three species are recorded from both northern and southern parts of the Peninsula. Specimens on which was based the record of A. macrotrichiata from North Korea was misidentified and no more specimens were collected; therefore, A. macrotrichiata is deleted from the Korean species list. Habitat, elevation range, and seasonality data is presented for each species. Images of taxonomically important morphological characters, and an identification key for all Palaearctic species of the genus Adelphomyia are presented. Distribution maps are presented for all Korean species.
