Seven species, T. akanensis ( Uchida, 1930) , T. daisetsuzanus ( Uchida, 1930) , T. fukuiyamensis ( Uchida, 1936) , T. maruyamanus ( Uchida, 1930) , T. pennulae (Uchida, 1932) , T. shanaensis ( Uchida, 1936) , and T. striatus ( Momoi, 1970) , have been recorded from Japan. I found more than ten undetermined species from Japan. The taxonomic treatment of these species requires the additional specimens and comparison with European species. In this study, I re-describe Th. fukuiyamensis and Th. maruyamanus .
