Phylogenetic relationships and biogeography of Northeast Asian Cryptocercus were inferred based on the DNA sequences of mitochondrial COII and 16S rRNA genes and nuclear 18S rRNA gene. The results suggest that two clades exist in Korean populations. The southwestern population (Cryptocercus from Jiri-san) was more closely related to the populations from Northeast China and eastern Russia than to all the other Korean Cryptocercus. According to molecular-based estimated divergence times, the divergence event occurred between Cryptocercus in Jiri-san, Northeast China and eastern Russia and those in the remaining South Korea during the Miocene (7.5-17.4Myr ago), and then the divergence event between Cryptocercus in Jiri-san and those in Northeast China and eastern Russia occurred 0.8-1.9Myr ago. In the Korean Peninsula, Jiri-san is located in the most southwestern region among the high mountains surveyed. The location is the farthest from Northeast China and eastern Russia among sampling localities in South Korea. Thus, it was unexpected that the southwestern populations are more closely related to those from Northeast China and eastern Russia rather than to the other Korean Cryptocercus. Based on Korean topography and estimated divergence times, possible scenarios are proposed for the current geographical distribution of Korean Cryptocercus.
基于线粒体COII和16S rRNA基因以及核18S rRNA基因的DNA序列，推断了东北亚隐尾蠊的系统发育关系和生物地理学。结果表明，韩国种群存在两个进化枝。韩国西南部种群（来自智异山的隐尾蠊）与中国东北和俄罗斯东部的种群关系比与其他韩国隐尾蠊更为密切。根据基于分子的估计分歧时间，分歧事件发生在中新世（750万至1740万年前），当时智异山、中国东北和俄罗斯东部的隐尾蠊与韩国其他地区的隐尾蠊之间出现分歧，然后智异山的隐尾蠊与中国东北和俄罗斯东部的隐尾蠊之间的分歧事件发生在80万至190万年前。在朝鲜半岛，智异山位于所调查高山中最西南部的地区。在韩国的采样地点中，该位置距离中国东北和俄罗斯东部最远。因此，西南部种群与中国东北和俄罗斯东部的种群关系比与其他韩国隐尾蠊更为密切，这一点出乎意料。基于朝鲜半岛的地形和估计的分歧时间，提出了韩国隐尾蠊当前地理分布的可能情况。
