A taxonomic study on the South Korean Diplonevra (Diptera: Phoridae)

The South Korean species of the genus Diplonevra are revised and eight species are recognized. Three of these species, D. biflagella, sp. nov., D. incisura, sp. nov., and D. nigritarsis, sp. nov., are new to science and four species, D. abbreviata (von Roser, 1840), D. florescens (Turton, 1801), D. hirsuta Michailovskaya, 2000, and D. peregrina (Wiedemann, 1830), are described for the first time in Korea. Distribution of D. bifasciata (Walker, 1860), the only previously recorded species in Korean checklists, is confirmed based on figures of a female specimen in previous publications. Diplonevra lamella Liu Yang, 2016 is considered a junior synonym of D. hirsuta Michailovskaya, 2000. The Chinese and Russian Far East records of D. pachycera (nec Schmitz) are treated as misidentifications of D. incisura, sp. nov. and D. nigritarsis, sp. nov., respectively. Also, the Chinese record of D. taigaensis (nec Michailovskaya) should be identified as D. biflagella, sp. nov. Detailed descriptions and photographs of three new species and four redescribed species and keys to eight males and seven females of Diplonevra species in South Korea are provided.
