ABSTRACT
We examined the evolutionary and ecological processes shaping current geographical distributionsof a Korean wood-eating cockroach species, Cryptocercus kyebangensis. Our research aims were to understandevolutionary pattern of DNA sequences, to construct genetic network of Cryptocercus kyebangensis local populationsand to understand evolutionary and ecological processes shaping their current geographical distributionpatterns via DNA sequence information and genetic networks, using sequence data of two genes (ITS-2 andAT region) from local populations of C. kyebangensis. The results suggest that the ITS-2 and AT region areappropriate molecular markers for elucidating C. kyebangensis geographic patterns at the population level. TheMSN-A based on the ITS-2 showed two possible routes, the Hwaak-san and Myeongji-san route and the Seoraksanand Gyebang-san route, for migration of ancestral C. kyebangensis into South Korea. The MSNs (MSN-Aand -B) elucidate migration routes well within South Korea, especially the route of Group Ⅰ and Group Ⅱ.
