中文摘要:
      快步麻蜥复合体(Eremias velox complex)分布于亚洲中部干旱区,不同地理居群形态和遗传变异较大。学界长期认为,快步麻蜥在我国有两个亚种:指名亚种(E. velox velox)和E. v. roborowskii亚种。前者分布于新疆准噶尔盆地和伊犁河谷;后者分布于新疆吐鲁番盆地,近年分类地位由亚种提升为种——吐鲁番麻蜥(E. roborowskii)。我们在吐鲁番市高昌区一万泉附近捕获到3只麻蜥,经过COI基因序列比对和系统发育关系重建以及外部形态比较,鉴定为快步麻蜥指名亚种。这是首次发现新疆天山以南存在快步麻蜥指名亚种分布,同时也确定为吐鲁番盆地的蜥蜴类分布新记录种,此发现可为研究快步麻蜥的谱系地理格局和演化历史提供基础资料。
英文摘要:
      The Eremias velox complex, a widespread racerunner in arid Central Asia, exhibits high morphological and genetic variability among different geographic populations. According to historical records, there are two subspecies of E. velox distributed in China, including E. v. velox from the Junggar Basin and the Ily River Valley, and E. v. roborowskii — elevated recently to a separate species E. roborowskii—endemic to the Turpan Basin. During herpetological surveys in May 2022 and July 2023, we captured three specimens of Eremias by hand near the Yiwanquan village of Gaochang District in Turpan City. To identify the taxonomic status of the three specimens, we used several methods as follow. We determined and complied the segments of the mitochondrial COIgene, and used Bayesian inference (BI) and maximum likelihood (ML) to reconstruct phylogenetic relationships. We calculated the uncorrected p-distance of different clades/subclades and compared the morphological characteristics.The morphological characteristics of the three specimens are consistent with those of E. v. velox (Fig. 2, 3 and Table 2), the results of phylogenetic relationships and haplotypes network (Fig. 4, 5) and genetic distance also indicated that the identity of the three specimens is E. v. velox.The occurrence of the nominate subspecies E. v. velox is a new reptile record of the Turpan Basin, which is also reported for the first time in the south of Tianshan Mountains. Our finding could provide basic data for further exploring the phylogeographic pattern and evolutionary history of the E. velox complex.
