Abstract
Dryadaulaepischista (Meyrick, 1936), initially described from a single male specimen in Japan, is herein redescribed based on newly collected specimens from the type locality. Furthermore, we describe Dryadaulaorientalis Park & Yagi, sp. nov., a new species from Japan that closely resembles D.epischista. The adults and genitalia of the two species are illustrated. The genitalia of D.epischista from a specimen collected at the type locality are shown for the first time. DNA barcodes of the two Dryadaula species and the genetic distances of barcode regions among them and other congeners are provided.
