隐尾蟑螂（CryptocercusScudder）是一种无翅的亚社会蟑螂属，具有较低的游动性，但在北美东部和西部以及中国，韩国和俄罗斯远东地区表现出间断性分布。这种分布提供了一个理想的模型，用于测试通过板块构造或其他自然屏障相对于跨洋扩散或跨越其他自然屏障的邻近假设。我们测定了45个隐尾虫线粒体基因组，以解决世界范围内该属成员之间的系统发育关系。我们确定了四种类型的tRNA重排样品从秦巴山区。基于线粒体基因组和核基因（18 S，28 S）的最大似然和贝叶斯系统发育树支持隐尾虫属的6个主要谱系，显示出明显的地理分布格局。我们使用贝叶斯分子测年来估计该属的进化时间尺度，并使用RASP中的统计分散-邻近分析（S-DIVA）重建隐尾丝虫的祖先范围。隐尾虫的两次扩散事件和六次迁移事件得到了很高的支持。80.5Ma时，美洲和亚洲谱系之间发生了初始的分隔事件（95%可信区间：60.0-104.7 Ma），其次是43.8 Ma的美洲谱系内的一次替代事件（95% CI：32.0-57.5 Ma）和两次扩散事件（31.9 Ma（95% CI：25.8-39.5 Ma）、21.7 Ma（95% CI：17.3-27.1 Ma）和四次邻近事件c。29.3在亚洲谱系中，分别为27.2Ma、24.8Ma和16.7Ma。我们的分析提供的证据表明，在塑造这些woodroaches的分布和多样性的替代和扩散发挥了重要作用。
CryptocercusScudder, a genus of wingless, subsocial cockroaches, has low vagility but exhibits a disjunct distribution in eastern and western North America, and in China, South Korea and the Russian Far East. This distribution provides an ideal model for testing hypotheses of vicariance through plate tectonics or other natural barriers versus transoceanic dispersal or across other natural barriers. We sequenced 45Cryptocercusmitochondrial genomes to resolve phylogenetic relationships among members of the genus worldwide. We identified four types of tRNAs rearrangements among samples from the Qin-Daba Mountains. Our maximum-likelihood and Bayesian phylogenetic trees, based on mitochondrial genomes and nuclear genes (18S,28S), strongly supported six major lineages ofCryptocercus, which displayed a clear geographical distribution pattern. We used Bayesian molecular dating to estimate the evolutionary timescale of the genus, and reconstructedCryptocercusancestral ranges using statistical dispersal-vicariance analysis (S-DIVA) in RASP. Two dispersal events and six vicariance events forCryptocercuswere inferred with high support. The initial vicariance event occurred between American and Asian lineages at 80.5 Ma (95% credibility interval: 60.0–104.7 Ma), followed by one vicariance event within the American lineage 43.8 Ma (95% CI: 32.0–57.5 Ma), and two dispersal 31.9 Ma (95% CI: 25.8–39.5 Ma), 21.7 Ma (95% CI: 17.3–27.1 Ma) plus four vicariance eventsc. 29.3 Ma, 27.2 Ma, 24.8 Ma and 16.7 Ma within the Asian lineage. Our analyses provide evidence that both vicariance and dispersal have played important roles in shaping the distribution and diversity of these woodroaches.
