The genus Coenosia Meigen, 1826 (Diptera: Muscidae) is reported from Korea for the first time, based on a morphological study of specimens collected from various regions of the country. Five species belonging to the C. flavimana and C. tigrina species groups are recognized. Two species, C. dolichotarsa sp. nov. and C. tenuiphallus sp. nov., are described as new to science, while three species, C. flaviambulans Xue, C. attenuata attenuata Stein, and C. strigipes strigipes Stein, are recorded from Korea for the first time. Diagnoses, morphological descriptions, and illustrations are provided for all five species, together with diagnoses of the two species groups and an identification key to males.
