摘　　要：通过分析比较了裂足轮虫 (Brachionusdiversicornis)、方型臂尾轮虫 (B .quadridentatus)、壶状臂尾轮虫 (B .urceus)、矩形臂尾轮虫 (B .leydigi)、萼花臂尾轮虫 (B .calyciflorus)等 5种轮虫的线粒体细胞色素氧化酶亚基I (COI)的部分序列 ,并结合 4种海水臂尾轮虫的序列数据 ,用西氏晶囊轮虫 (Asplanchna .sieboldi)作外群构建UPGMA树和NJ树 ,探讨了裂足轮虫的分类学问题 .The mtDNA COI sequences (299 bp) from 5 different Brachionus species are analyzed. The sequences are compared, the frequency of nucleotide is calculated and the molecular phylogenetic trees are constructed by UPGMA and Neighbor Joining method using A.sieboldi as outgroup. The phylogenitic trees suggeste that B.diversicornis is closer to Brachionus group, thus it is more appropriate to include B.diversicornis in the Brachionus group.
