我们根据2015年Auritibicen Lee属的10个新种：a . aethus sp. n.、a . daxianensis sp. n.、a . pallidus sp.、a . rotundus sp. n.、a . curvatus sp.、a . purus sp.、a . parvus sp.、a . gracilis sp.、a . septatus sp.和a . lijiangensis sp.的描述，对Auritibicen Lee（加藤，1959）进行了回顾。诊断和描述，连同插图的男性生殖器的结构，提供了所有的Auritibicen物种。从形态学和分子学两个方面对Auritibicen的系统学进行了阐述。对24种Auritibicen和1个外群分类单元Chremistica ochracea （Walker, 1850）的35个形态特征进行了评分。形态学系统发育分析揭示了该属近缘种间的亲缘关系，并得到许多形态学特征的支持。对11种Auritibicen和2个外群Lyristes的线粒体细胞色素氧化酶I （Cytochrome Oxidase I， COI）基因片段进行了分析，得到了相同的健壮的系统发育树。基于形态学和分子数据的贝叶斯分析的系统图谱与仅基于分子数据的ML/BI拓扑相似。分子系统发育分析表明，该物种具有系统地理结构，亲缘种聚在3个谱系中。根据分子资料估计的分化时间表明，奥立比色系与Lyristes的分化发生在中新世，而奥立比色系最近的共同祖先（tMRCA）演化于上新世。而奥立比种的主要分化事件发生在更新世。结合系统发育和最新地理分布，我们推测该属的分布中心可能在中国西南部（如四川和云南），从那里沿秦岭和大巴山向东北扩散到陕西、湖北和其他省份，然后再向东北扩散到中国河北省、俄罗斯远东地区、朝鲜半岛和日本。
We review the cicada genus Auritibicen Lee, 2015 based on the description of ten new species: A. aethus sp. n., A. daoxianensis sp. n., A. pallidus sp. n., A. rotundus sp. n., A. curvatus sp. n., A. purus sp. n., A. parvus sp. n., A. gracilis sp. n., A. septatus sp. n. and A. lijiangensis sp. n. Auritibicen shikokuanus (Kato, 1959) is confirmed to be a synonym of Auritibicen kyushyuensis (Kato, 1926). Diagnoses and descriptions, along with illustrations of the structure of male genitalia, are provided for all Auritibicen species. The systematics of Auritibicen is elucidated using both morphological and molecular characterization. Thirty-five morphological characters of the 24 species of Auritibicen and one outgroup taxon, Chremistica ochracea (Walker, 1850), were scored. Morphological phylogenetic analyses reveal the relationships among related species of Auritibicen, which are supported by a number of morphological characters. The mitochondrial gene fragments of Cytochrome Oxidase I (COI) of 11 species of Auritibicen and two outgroup Lyristes species were analyzed and yielded identical robust phylogenetic trees. The phylogram based on a Bayesian analysis of both morphological and molecular data is similar to the ML/BI topologies based only on the molecular data. The molecular phylogenetic analysis indicates that species of Auritibicen are structured phylogeographically, with related species clustered into three lineages. The divergence time estimated based on molecular data indicates that the divergence of Auritibicen from Lyristes occurred during the Miocene, and the most recent common ancestor (tMRCA) of Auritibicen evolved during the Pliocene. However, the time when the main divergence events of species of Auritibicen occurred was the Pleistocene. From the combination of the phylogeny and updated geographical distributions, we infer that the center of distribution of Auritibicen could be Southwest China (e.g., Sichuan and Yunnan Provinces), from where species of this genus spreaded northeastwards to Shaanxi, Hubei and other provinces along the Qinling and Daba Mountains, then further northeastwards to Hebei Province in China and also to Far East Russia, the Korean Penisula, and Japan.
