A single species, Or. triannulatum (Thomson, 1884), has been recorded from Japan. I found more than 10 species of this genus from Japan. The taxonomic treatment of these species requires the additional specimens and comparison with European species. In this study, I record Or. semanotae Sheng & Sun, 2014 from Japan for the first time.
