双栉虫科和蛰龙介科(环节动物门,多毛纲)分类学研究

Study on the Taxonomy of Families Ampharetidae and Terebellidae(Annelida,Polychaeta)

双栉虫科和蛰龙介科是环节动物多毛纲蛰龙介目中两个大科,种类多,形态和生活习性变化大,多样性高,全为海生,从海滨至深海均有分布,尤其在潮间带和近岸环境种类异常繁多,地区性特点显著,是重要的底栖环节动物,也是海洋底栖生态系的重要生物组成成分,具有重要生态学和生物多样性价值。由于其系统演化的复杂性和分类系统的混乱,造成大量属存在并系、多系现象,分类困难,系统发育关系不清,因此,对其生物多样性和动物地理学研究将十分有意义。

The families Ampharetidae and Terebellidae are two largest families in the order Terebellida of the Annelida class Polychaeta.Species of thses two families are very specious due to variable morphology and high species diversity.All the species of the two families are marinelived and their distribution ranges from seashore to deep sea,mainly in the habits of intertidal zone and shallow waters,with many endemic species.The two families are important benthic Annelida groups,playing an important roles in marine ecosystems and biodiversity.Because of their variable morphology and complicated habits,it is hard to study their phylogeny and zoogeography.The knowledge of their faunal characteristis from China seas is poor.We reviewed the biodiversity and zoogeography of two families in this paper to provide basic information for further study.
