In Korea, twelve species in genus Myrmica have been described. Some of them are morphologically similar and this makes their identification difficult. For this reason, we collected several Myrmica species in question and inferred their phylogenetic relationship using the 418bp partial COI (cytochrome C oxidase 1) region from a total of 33 individuals. We found that the CO1 haplotypes are effectively grouped into three clusters that match well to their external morphological characters. Although this three species could be distinguished by the only small part of the COI region, the two individual sample of the M. kotokuii and one sample of the M. carinata are included in the M. kurokii group. The results indicate that the morphological identification could be obscure in the three species and it requires a close examination for this phenomenon.
