Abstract

This paper describes four new species earthworms from Hunan and Anhui provinces, China, Amynthasxiangtanensis Qiu & Jin, sp. nov., Amynthastaoyuanensis Qiu & Jin, sp. nov., Amynthasxuanchengensis Jin & Li, sp. nov. and Metaphiredonganensis Jin & Jiang, sp. nov. Amynthasxiangtanensis sp. nov., and A.taoyuanensis sp. nov. belong to the Amynthascorticis group. Both have four pairs of intersegmental spermathecal pores in 5/6-8/9; male pores in segment XVIII, separated by 1/3 of body circumference, each on top of a slightly raised porophore, surrounded by several tiny genital papillae. Amynthastaoyuanensis sp. nov. prostate glands are degenerated. Amynthasxuanchengensis sp. nov. belongs to the Amynthasmorrisi group, it has two pairs of spermathecal pores in 5/6 and 6/7; male pores in XVIII, separated by 1/3 of body circumference, each on top of a slightly raised, circular porophore. Metaphiredonganensis sp. nov. belongs to the Metaphirehoulleti group. It has three pairs of spermathecal pores in 6/7-8/9; male pores in XVIII, separated by 1/3 of body circumference, each on the bottom center of the longitudinal copulatory chamber.

中国湖南省和安徽省的四种蚯蚓新种：Amynthas 属和 Metaphire 属（寡毛目，Megascolecidae）。

本文描述了产于中国湖南和安徽省的4个新种蚯蚓，即湘潭蚯蚓（Amynthasxiangtanensis Qiu & Jin，sp. nov.）、桃源蚯蚓（Amynthastaoyuanensis Qiu & Jin，sp. nov.）、宣城蚯蚓（Amynthasxuanchengensis Jin & Li，sp. nov.）和澧县蚯蚓（Metaphiredonganensis Jin & Jiang，sp. nov.）。Amynthasxiangtanensis sp.nov.和 A.taoyuanensis sp.nov.属于 Amynthascorticis 组。两者都在 5/6-8/9 节有四对节间精巢孔；在第十八节有雄性精巢孔，相隔体周的 1/3，每个精巢孔都在一个略微凸起的孔柄顶部，周围有几个微小的生殖器乳突。Amynthastaoyuanensis新种的前列腺退化。Amynthasxuanchengensis sp. nov.属于 Amynthasmorrisi 类，在 5/6 和 6/7 有两对精巢孔；在 XVIII 有雄性精巢孔，相隔体周的 1/3，每个精巢孔都位于一个略微凸起的圆形孔隙之上。Metaphiredonganensis sp.它在 6/7-8/9 有 3 对精巢孔；在 XVIII 有雄性精巢孔，相隔体周的 1/3，每个精巢孔位于纵向交配室的底部中心。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
