中国涡虫的分类概况及分科检索表

Taxonomic Review of Planarians from China with a Key to the Families

涡虫隶属扁形动物门Platyhelminthes,作为最早出现的三胚层动物,在动物的进化中具有重要意义,也是重要的环境指示动物和再生生物学的模式生物。涡虫学已成为世界最活跃的研究领域之一。涡虫在全世界分布广泛、种类丰富,但我国的相关分类研究进展较慢。近年来,我国的涡虫研究手段和论文发表档次已达到国际领先水平,并取得了不少进展,但仍存在调查和研究范围局限、大量工作尚待开展等不足。本文总结了国内外涡虫分类的研究历史和现状,介绍了目前高级阶元的分类系统,并更新了我国涡虫种类名录,共计2亚门7目26科44属131种/亚种,首次编制了我国涡虫分目分科检索表。研究结果旨在为涡虫分类和系统发育研究服务,推动涡虫在环境调查和再生医学等相关领域的研究。

Planarians are the earliest tri-embryonic animals belonging to the phylum Platyhelminthes with great evolutionary significance.Planarians are also important environmental indicators and model animals for regenerative biology.Planarianology has become one of the active research fields in the world because of their extraordinary regenerative ability.Although planarians distributed worldwide with rich diversity,the taxonomy research of them in China developed relatively slowly.In recent years,research groups of China have made several progresses on the taxonomy of planarians.However,there are still shortcomings in the investigation and research scope.Obviously,a lot of work still needs to be carried out in further.Herein,we summarized the history of taxonomic research and the current situation,introduced the new classification system on high taxa,and updated the checklist of planarian from China.The results indicated that there were 131 planarian species/subspecies belonging to 2 subphylums,7 orders,26 families and 44 genera.A key to the families of planarians from China are compiled firstly from China.This study contributes to the classification and phylogeny of planarian,and the research on environmental monitoring and regenerative medicine.
