Five previously known species were attributed to the species group, including (Pic 1926), (Gorham 1889), (Švihla 2004), (Fairmaire 1887), and (Wittmer, 1995). Four new species of this group were discovered from China and Vietnam, sp. nov., sp. nov., sp. nov., and sp. nov. An updated key to all species was provided. A geographical distribution map is presented, which shows that all the members were located between 18.69041-33.93441° N, and between 98.61413-121.77102° E. The ancestral geographical range was reconstructed based on a phylogeny of morphological data by the Bayesian Binary MCMC method. The result showed that the spatial origin of species group was probably located in northern Vietnam and southwest China. The divergence of the species in southwest China and Taiwan was caused by vicariance about 24 Ma ago, when the latter was separated in the Qinghai-Tibet Plateau, and the remaining species of mainland China all originated from Taiwan after traveling around Southeast Asia and back to China. Nevertheless, this conclusion should be verified when fossil evidence and molecular data are available.
该物种组包括五个先前已知的物种，即（Pic，1926年）、（Gorham，1889年）、（Švihla，2004年）、（Fairmaire，1887年）和（Wittmer，1995年）。该组的四个新物种在中国和越南被发现，即新物种、新物种、新物种和新物种。提供了所有物种的最新检索表。给出了地理分布图，图中显示所有成员位于北纬18.69041 - 33.93441°，东经98.61413 - 121.77102°之间。基于形态学数据的系统发育，采用贝叶斯二元MCMC方法重建了祖先地理范围。结果表明，该物种组的空间起源可能位于越南北部和中国西南部。中国西南部和台湾物种的分化是由约2400万年前的地理隔离造成的，当时台湾从青藏高原分离出来，中国大陆的其余物种都是在环游东南亚后回到中国并从台湾起源的。然而，当有化石证据和分子数据时，这一结论应予以验证。
