A diversification of external morphology and genital characteristics among conspecific animal populations that are geographically divided is particularly important to study the context of evolution and it is regarded as the early stage of allopatric speciation. The aim of the present study is to understand the morphological variations of Callipogon relictus Semenov from the three different populations (South Korea, China, Russia) in the Eastern Palaearctic region. A morphometric analysis was performed based on 87 selected external and internal characteristics from 95 specimens. As results of the present study, South Korean specimens shows remarkable morphological differences in genital characteristics compare to Russian ones. In Principal Component Analysis (PCA), South Korean and Russian populations are divided into two groups and the Analysis of Variance (ANOVA) analysis indicate that these two populations have significant differences in 14 morphometric characteristics.
