摘要
在印度孟加拉湾的东北海岸发现了一种半陆生单生单栖动物。组织学研究证实其隶属于Prosadenoporus b rger, 1890。在这篇论文中，它被描述为一个新种，Prosadenoporus indicus sp. 11 .这个物种与它的同属物种不同，它的头的前背表面有一个明显的黑色斑块，身体很大，有16-18个喙神经，一个大的额器官，神经索细胞的存在，以及舌部周围只有圆形的肌肉。对658 bp的细胞色素c氧化酶亚基I （COI）基因序列进行最大似然分析，包括该物种的数据和公共数据库中的5个同源基因，支持该新种的属位。该新种的658 bp COI序列与同系种相比，未校正的p距离差异为10.3-11.1%。
A New Species of Prosadenoporus (Nemertea: Eumonostilifera) from the North-East Coast of the Bay of Bengal, India.
A semi-terrestrial eumonostiliferous hoplonemertean species was discovered on the northeastern coast of the Bay of Bengal, India. Histological studies confirmed its affiliation with the genus Prosadenoporus Bürger, 1890. In this paper, it is described as a new species, Prosadenoporus indicus sp. nov. This species is distinguished from its congeners by a distinct black patch on the antero-dorsal surface of the head, a large body size, 16-18 proboscis nerves, a large frontal organ, the presence of neurochord cell, and exclusively circular muscles surrounding the rhynchodeum. A maximum-likelihood analysis of 658-bp cytochrome c oxidase subunit I (COI) gene sequences, including data from this species and five congeners available in public databases, supported the generic placement of the new species. The new species exhibited 10.3-11.1% uncorrected p-distance differences in 658-bp COI sequences compared to its congeners.
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.
