Pseudopomyzidae (Diptera: Nerioidea) is rare and a small family of dark-colored acalyptrate flies, comprising 24 extant species in eight genera and two fossil species in a single genus. To date, only one species Pseudopomyza atrimana (Meigen, 1830) has been recorded in the Korean Peninsula. This study reports the first Korean records of the family Pseudopomyzidae, with two genera and two species, Polypathomyia stackelbergi Krivosheina, 1979 and Tenuia smirnovi Shatalkin, 1995. A key to Korean Pseudopomyzidae is provided with morphological diagnosis and illustrations of habitus and genital structures of males.
