摘要

本文报道了一种新的具有分枝喙部的线系异重蝇，Polydendrorhynchus amaleshii sp. nov.，作为Polydendrorhynchus Yin and Zeng（1986）继Polydendrorhynchus zhanjiangensis （Yin and Zeng, 1984）之后的第二个成员。这一描述是基于从孟加拉湾东北部海岸收集的标本，包括印度孙德尔本斯红树林生态系统中的Subarnarekha河口和Frazerganj。这个新物种与它的同系物的区别在于它的喙上有多达56个末端小枝，而且没有喙室。基于COI基因和16S rRNA基因的最大似然系统发育分析表明，阿玛氏p.a maleshii和湛江p.a形成了一个支持良好的支系。Polydendrorhynchus amaleshii是在印度记录的第9种nemertean物种。

Polydendrorhynchus amaleshii sp. nov., a New Species With Branched Proboscis (Nemertea: Heteronemertea) From the North-East Coastal Bay of Bengal.

A new lineid heteronemertean with a branched proboscis, Polydendrorhynchus amaleshii sp. nov., is described as the second member of the genus Polydendrorhynchus Yin and Zeng, 1986, following Polydendrorhynchus zhanjiangensis (Yin and Zeng, 1984). The description is based on specimens collected from the northeastern coastal Bay of Bengal, including the Subarnarekha Estuary and Frazerganj in the Indian Sundarbans mangrove ecosystem. The new species is distinguished from its congener by having up to 56 terminal branchlets of the proboscis and the absence of rhynchocoel compartments. In a maximum-likelihood phylogenetic analysis based on COI and 16S rRNA genes, P. amaleshii and P. zhanjiangensis formed a well-supported clade. Polydendrorhynchus amaleshii represents the ninth nemertean species recorded from India.

期刊介绍： Zoological Science is published by the Zoological Society of Japan and devoted to publication of original articles, reviews and editorials that cover the broad field of zoology. The journal was founded in 1984 as a result of the consolidation of Zoological Magazine (1888–1983) and Annotationes Zoologicae Japonenses (1897–1983), the former official journals of the Zoological Society of Japan. Each annual volume consists of six regular issues, one every two months.
