Phygadeuon genus group

(subtribe Phygadeuontina sensu Townes (1970) and Horstmann (1992))

Seven genera, Gnotus Förster, 1869, Phygadeuon Gravenhorst, 1829, Sulcarius Townes, 1970, Theroscopus Förster, 1850, Tricholinum Förster, 1869, and Uchidella Townes, 1957, have been recorded from Japan. In addition, I found Megacara, Stibeutes, and Tropistes from Japan. In this study, I newly record Megacara and Tropistes from Japan and review Gnotus, Orthizema, and Uchidella . The taxonomic treatment of Stibeutes requires the additional specimens and comparison with European species. The identification of genera see Townes (1970).
