摘要
关于牛首科 (即腹口类 )吸虫的分类地位 ,一直存在着意见分歧 ,一种观点认为牛首科所代表的腹口类与前口类应作为两个分别独立而并列的分类单元 ;另一种观点认为腹口类在分类上应归于前口类中的某一分类单元。本文通过对牛首科吸虫的特征分析以及与前口类吸虫的比较 ,发现牛首科吸虫在成虫、毛蚴、胞蚴、尾蚴、宿主类型、染色体等方面都与前口类有显著差别。因而支持前一种分类观点 ,不应将牛首科放入前口类中。
Regarding the systematic position of Bucephalids there are two major different viewpoints. Some of the helminthologists suggested Gasterostomes, with the only family Bucphalidae Poche, 1907, and Prostomes should be two independent and paratactic taxa in Digenea. Others suggested the Gasterostomes should belong to one of the taxa in Prostomes. In the present study several features of Bucephalids (Gasterostomes) are analyzed and compared with those of Prostomes. The evident differences between Bucephalids and Prostomes in the features of adults, miracidia, sporocysts, cercariae, hosts and chromosomes are found. The results support the former taxonomic viewpoints, i.e. the Bucephalids should be independent from rather than belong to the Prostomes.
