Abstract:
During our collecting trip to Guangxi in 2016, we collected ten specimens of the genus Takydromus from the suburb of Guilin, northeastern Guangxi, South China, and found that they did not belong to any currently known species. Here, we described this new species, Takydromus guilinensis sp. nov., based on morphological and mitochondrial DNA (CO1 and cyt b) data. This new species is a sister taxon to T. intermedius with a p-distance of 0.070 in CO1 and 0.080 in cyt b. These two p-distances exceed not only the minimum value (0.067) between T. septentrionalis and T. stejnegeri but also the minimum value (0.079) between T. intermedius and T. yunkaiensis. Morphologically, this new species differs from other currently recognized Takydromus species from the same clade, more evidently in the longitudinal rows of dorsal scales, transverse rows of scales at the mid-body and mensural variables. The description of Takydromus guilinensis sp. nov. increases the total number of Takydromus species to 25, of which 16 can be found in China. Takydromus guilinensis sp. nov. is currently known only from Guilin, Guangxi, South China, where it is sympatric with the other four Takydromus species (T. septentrionalis, T. kuehnei, T. sexlineatus and T. intermedius).
摘要:
在2016年广西采集之旅中,我们从桂林市郊区采集了10个Takydromus属标本,广西东北部,华南,并发现它们不属于任何目前已知的物种。这里,我们描述了这个新物种,杜鹃。11月。,基于形态学和线粒体DNA(CO1和cytb)数据。这个新物种是T.intermedius的姐妹分类单元,CO1中的p距离为0.070,cytb中的p距离为0.080。这两个p距离不仅超过了T.septentrionalis和T.stejnegeri之间的最小值(0.067),而且超过了T.intermedius和T.yunkaiensis之间的最小值(0.079)。形态学上,这个新物种不同于目前公认的来自同一进化枝的其他Takydromus物种,更明显的是在背鳞的纵向行中,中体和月经变量的横行尺度。石竹的描述。11月。将Takydromus物种的总数增加到25种,其中16种在中国。杜鹃。11月。目前仅从桂林知道,广西,华南,与其他四个塔夫罗姆属物种(T.隔膜,T.Kuehnei,T.sexlineatus和T.intermedius)。
