Abstract

ABSTRACT A new species of head-shield sea slug, Melanochlamys bengalensis, is described from the northern part of the eastern coast of India using both external and internal morphological characters. Its novel status is supported by a molecular analysis. The maximum likelihood (ML) genetic tree (COI gene sequence) indicates that the new species represents a distinct clade compared to the other species of the genus Melanochlamys. The K2P distance of the new species is 16.2–23.7%, which is considerably more than the other congeners. This species was collected from the intertidal zone of the sandy beaches of Bakkhali, Tajpur, New Digha, Udaipur, Talsari, Chandipur and Kanika Island. Additionally, the list of valid species and distribution of all members of the genus Melanochlamys is presented herein.

印度孟加拉湾的一种Melanochlamys Cheeseman属的头棘海蛞蝓新种，1881（异鳃亚目：Aglajidae）

摘要利用外部和内部形态特征，描述了印度东海岸北部的一种新的头盾海蛞蝓Melanochlamys bengalensis。分子分析支持了它的新地位。最大似然（ML）遗传树（COI基因序列）表明，与黑霉属的其他物种相比，新物种代表了一个独特的分支。新物种的K2P距离为16.2~23.7%，远大于其他同类物种。该物种采集于Bakkhali、Tajpur、New Digha、Udaipur、Talsari、Chandipur和Kanika岛沙滩的潮间带。此外，本文还列出了黑色素蝶属所有成员的有效物种和分布列表。

期刊介绍： Molluscan Research is an international journal for the publication of authoritative papers and review articles on all aspects of molluscan research, including biology, systematics, morphology, physiology, ecology, conservation, biogeography, genetics, molecular biology and palaeontology. While the scope of the journal is worldwide, there is emphasis on studies relating to Australasia and the Indo-west Pacific, including East and South East Asia. The journal’s scope includes revisionary papers, monographs, reviews, theoretical papers and briefer communications. Monographic studies of up to 73 printed pages may also be considered. The journal has been published since 1957 (as the Journal of the Malacological Society of Australia until 1993). It is free to members of the Malacological Society of Australasia and the Society for the Study of Molluscan Diversity.
