A new species, Acidon sugii sp. nov. is described from Ani-jima, Chichi-jima and Haha-jima Islands of the Ogasawara Islands, Japan with illustrations of the male and female genitalia. The genus Acidon is newly recorded from Japan. The new species can be distinguished from the closely related species, A. calcicola by the bipectinate male antennae and short and centrally obtusely flexed aedeagus. Perciana marmorea and Hepatica nakatanii are successfully distinguished using standard DNA barcoding.
