10. Trigomphus melampus (Selys, 1869) View in CoL

= Gomphus unifasciatus Oguma, 1926

Gomphus unifasciatus Oguma, 1926 View in CoL , p. 92, 3, “Hokkaido (Nayoro, Komura)” (syn. nov.).

This species was originally described from three specimens (1 ♂ Nayoro, Hokkaido; 1 ♂ Komaba, Tokyo; 1 ♀ Kagoshima, Kyusyu), but at present there is the single specimen (lectotype) in the collection. This and the Komaba-specimen which I examined in 1935 are actually the same with G. melampus Selys (1869), hence unifasciatus Oguma should be suppressed as a synonym of it. I also ascertained in 1935 that the female of unifasciatus Oguma is an entirely different species, which is now treated as Trigomphus citimus tabei Asahina (1949).
