中国短沟蜷科(腹足纲:蟹守螺超科)的系统分类

Systematic relationships of Chinese freshwater semisulcospirids (Gastropoda, Cerithioidea) revealed by mitochondrial sequences

  • 摘要: 短沟蜷科(Semisulcospiridae)种类隶属于软体动物门(MOLLUSCA)、腹足纲(GASTROPODA)、中腹足目(MESOGASTROPODA)。分布于北美西部和亚洲的中国、日本、韩国、越南、泰国、印度和俄罗斯东部等国家,多栖息于水质清洁的溪流、湖泊和龙潭中。本研究收集了中国短沟蜷科大部分已记录的种类,基于线粒体基因(COI和16S rRNA)所构建的系统发育树结果显示,中国短沟蜷科种类分别隶属于短沟蜷属(Semisulcospira B?ttger, 1886)、华蜷属(Hua Chen,1943)和韩蜷属(Koreoleptoxis Burch and Jung, 1988)。3个属之间可以通过繁殖方式(短沟蜷属种类为卵胎生,华蜷属和韩蜷属种类为卵生)、齿舌上的差异(华蜷属种类中央齿下缘具一对小齿,韩蜷属种类中央齿下缘具一个小齿,短沟蜷属种类中央齿下缘无小齿),以及分布范围相区别。

     

    Abstract: The systematics of Semisulcospiridae in China is revised here based on morphological characters and mitochondrial phylogenetics. Phylogenetic relationships within the Chinese semisulcospirids were assessed via DNA sequences from mitochondrial analysis (cytochrome c oxidase I and 16S rRNA). This research contains most morphospecies of semisulcospirids previously recorded in China. Based on these results, the family of Chinese Semisulcospiridae is represented by three genera: i.e., viviparous Semisulcospira B?ttger, 1886, oviparous Hua Chen, 1943 and Koreoleptoxis Burch and Jung, 1988. These genera can be distinguished from each other by reproductive anatomy, reproductive mode, and radula features. Species of Hua are mainly distributed in southwest China and Guangxi, whereas Koreoleptoxis and Semisulcospira are mainly distributed in south and northeast China.
