根据线粒体COII、16 S rRNA基因和核18 S rRNA基因的序列分析，推测了东北亚隐尾虫的系统发育关系和系统进化关系。结果表明，两个分支存在于韩国人群。西南部的隐尾虫种群与中国东北和俄罗斯东部的隐尾虫种群的亲缘关系较近。根据分子生物学方法估算的分化时间，自日山隐尾虫与韩国其他地区隐尾虫的分化发生在中新世（750 - 1740万年前），自日山隐尾虫与中国东北和俄罗斯东部隐尾虫的分化发生在080 - 1900万年前。在朝鲜半岛，知里山位于所调查的高山中的最西南部地区。该地点是韩国采样地点中距离中国东北和俄罗斯东部最远的。因此，这是出乎意料的，西南人口更接近中国东北和俄罗斯东部，而不是其他朝鲜隐尾虫。根据韩国的地形和估计的分歧时间，可能的情况下，提出了目前的地理分布的韩国隐尾虫。
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.
