DNA barcoding and morphological analyses of Korean Lymantria (Erebidae, Lepidoptera) were conducted for quarantine inspection. In DNA barcoding, Lymantria dispar identified through quarantine inspection was distinguished as three species, L. dispar asiatica, L. albescens, and L. xylina. Lymantria monacha, which is known as a single species in Korea, is revealed as containing three species, L. monacha, L. minomonis, and L. sugii. At the subspecies level, L. dispar dispar formed a single cluster, whereas L. d. asiatica and L. d. japonica formed a cluster containing both subspecies. In morphological re-examination on DNA barcoding results, L. dispar was distinguished from L. albescens by wing pattern, and from L. xylina by papillae anale. L. monacha and the related species were hard to be distinct from each other by using wing pattern, but it was easily distinct through comparison of genitalia. Therefore, DNA barcoding led to accurate identification in species level, but in subspecies level, only a taxon showing geographically far distance was discriminated from the others. These results may provide a taxonomic outline of the Korean Lymantria fauna and may be used as an identification reference for Lymantria species during quarantine inspection.
