This study was carried out to know some regional gene difference in carabid beetle, Coptolabrus jankowskii. There are eight subspecies in this species from Korea and it was too difficult to identify by morphological similarity.
The mitochondrial ND5 (NADH dehydrogenase subunit 5) gene of Coptolabrus jankowskii from four regions of (Sangju, Daegu, Mt. Jumbong and Jeju island) was compared. The results showed the differences of the base sequence of total 57 sites and the amino acid variation of the 25 sites. The Neighbor-joining tree and Maximum parsimony tree were established based on sequence data of the ND5. In NJ tree, the Jeju area except Songdangri, and Mt. Jeombong region showed close relationship group. In the case of Maximum parsimony tree, the result divided to three separated group, the first connected group was Jeju Songdangri area and the other the Korean peninsula region except Mt. Jeombong. Others were Jeju area except Songdangri, and Mt. Jeombong region.
