21. “ Aeschna juncea angustistyla Oguma”, 1915

Aeschna juncea anguslistyla Oguma, 1915 b , p. 124 (Karafuto); Oguma, 1926, p. 80, “Sachalin ”.

Two male specimens labelled, “Otasan, 1. VIII. ” and “Niitoi, 11. VIII. ’14” may be the types, the latter is chosen as lectotype. As the “ juncea ” in the Far East needs a careful review, I now tentatively use Oguma’s “ angustistyla . ”
