【摘要】：本研究利用18种蛾螺总科(Buccinoidea)动物的COⅠ基因序列对中国海蛾螺科进行了科上和科内水平的分子系统学分析。在建立的系统发育树中,蛾螺科种类聚成了4个明显的分枝:第一枝包括侧平肩螺(Japelion latus)、朝鲜蛾螺(Buccinum koreana)、黄海蛾螺(Buccinum yokomaruae)、皮氏蛾螺(Voluthapaperryi)、香螺(Neptunea cumingi)、小鼠脊蛾螺(Lirabuccinum musculus)以及褐线蛾螺(Japeuthria cingulata);第二枝包括莫氏角亮螺(Antillophos monsecourorum)和尖鱼篮螺(Nassaria acuminata);第三枝包括黑口甲虫螺(Cantharus melanostoma)和矛唇齿螺属(Engina lanceolata);第四枝包括褐管蛾螺(Siphonalia spadicea)和长吻真螺(Euthria lubrica)。该结果与先前基于形态分析进行的亚科划分基本一致。蛾螺科的单系性没有得到支持,织纹螺科种类(Nassarius thachi、N.sinarus、N.euglyptus)插到蛾螺科系统树中并与角亮螺属(Antillophos)及鱼篮螺属(Nassaria)聚成一枝;东风螺科种类(Babylonia areolata、B.spirata)和榧螺科种类(Oliva mustelina)与褐线蛾螺(Japeuthria cingulata)聚成一枝。东风螺属起初隶属于蛾螺科,现已被移出并作为单独的一科——东风螺科Babyloniidae,本研究确认了这一结论。鱼篮螺属(Nassaria)和角亮螺属(Antillophos)与织纹螺属(Nassarius)种类聚在一起,这与最近的分子研究得到的结果一致。
[Abstract]:In this study, CO I gene sequences of 18 species of (Buccinoidea) species in the China Sea were used to analyze the molecular phylogeny of the family Mostronidae and the Kone level. In the phylogenetic trees established, the species of the family Mothidae are clustered into four distinct branches: the first branch includes (Japelion latus), (Buccinum koreana), (Buccinum koreana), Huang Hai, (Buccinum yokomaruae), (Voluthapaperryi), (Neptunea cumingi),. Mouse (Lirabuccinum musculus) and (Japeuthria cingulata); The second is (Antillophos monsecourorum) and the third is (Cantharus melanostoma) and the fourth is (Siphonalia spadicea) and (Euthria lubrica). This result is consistent with the previous subfamily division based on morphological analysis. The monophyletic character of the family Mothidae was not supported, and the species of Nassarius thachi,N.sinarus,N.euglyptus were inserted into the systematic tree of the family Mothidae and formed a branch with (Antillophos) of the genus (Antillophos) and (Nassaria) of the genus (Nassaria). The species of Babylonia areolata,B.spirata and (Oliva mustelina) of Torreya are clustered into one branch with (Japeuthria cingulata). The genus Euphorbia, originally belonging to the family Mothidae, has been removed from the family Babyloniidae, which is a separate family. This study confirms this conclusion. The species of (Nassaria), (Antillophos) and (Nassarius) are clustered together, which is consistent with the results of recent molecular studies.
