Abstract: Japanese species of the genus Epiphragma Osten Sacken, 1860 are revised. Epiphragma amamiense sp. nov. is described, and E. gracilistylus Alexander, 1933 and E. kempi Brunetti, 1913 are recorded from Japan for the first time. It is revealed that records of E. evanescens Alexander, 1940 from Japan were based on misidentifications of E. gracilistylus and E. trichomerum Alexander, 1955. Therefore, a total of six species are recognized from Japan, and the previous records which based on misidentifications are corrected. Male and female terminalia of these six species are illustrated and a key to these species is provided.
