Remarks. Sasaki (2012) hinted the association of this species with coastal sand-dunes. The present data corroborates his proposal. The genus Maliarpha Ragonot, 1888 is reported for the first time from Korea. It currently comprises eight species occurring in East Asia, India, Papua New Guinea, and Ethiopian regions.
