18. Onychogomphus viridicostus ( Oguma, 1926)

Lindenia viridicosta Oguma, 1926 , p. 96, “Honshu (Tokyo, Horoshima)”, ♂ ♀.

In 1935 I found two males labelled as “Tokyo, Uchida” and “Kamiishi-gun (Hiroshima), Urakami”, and a female specimen labelled only “ 27. VII. ’91”. But now remains the Tokyo-specimen which should be designated as the lectotype.
