We tested the identification ability of DNA barcodes comparing with morphological data using the Korean butterflies. The 921 samples (4.6 samples per species) for 202 resident Korean species except migratory species were used. The obtained samples were morphologically identified based on wing patterns. In a result, genetic divergence to the nearest-neighbouring taxon varied from 0 to 28.2%, with an average of 13.4 per cent. The neighbour joining (NJ) tree profile showed that sequence data for 185 of the 202 species formed distinct barcode clusters. Thus, our results indicated that 91.6 percent of the species were possible to allow the reliable identification using DNA barcoding. The rest 17 species (8.4%) consist of following four cases: clustering separated from each species by less than 1% branch length (two species pairs), paraphyletic clustering (two species pairs and one triple species pair), polyphyletic clustering with sharing barcodes (three species pairs), and clustering separated from existing species by the deep branch divergence (four clusters). However, it was not easy to interpret these ambiguous cases only using our current taxonomic evidences. Therefore, we are performing integrative taxonomy on these cases using other additional evidences such as examination on male genitalia and analysis of other gene regions.
