Dendrolimus superans (Lepidoptera: Lasiocampidae) has long been acknowledged to present in South Korea under the circumstance of a substantial change in species names of Dendrolimus. In the present study, we found that specimens of D. superans collected from South Korea were D. sibiricus, rather than D. superans. Comparison of Korean specimens to the D. superans from Japan and the D. sibiricus from Russia in terms of wing morphology, female and male genitalia, a partial COI gene sequence, and a partial internal spacer sequence 2 (ITS2) consistently supported the presence of D. sibiricus in South Korea. Phylogenetic analyses using concatenated sequences of COI and ITS2 from available individuals of D. sibiricus and D. superans both by Bayesian inference and maximum likelihood methods the Korea samples to be D. sibiricus.
