Abstract

ABSTRACT A new species of Diplommatina Benson, 1849 from Sikkim, Northeast India is described based on shell morphology. This new species is found to be distinct in its externally visible large parietal tooth, and in the absence of a columellar tooth on the shell aperture. A detailed comparison with the closest congeners of the new species is provided. Diplommatina bidentata Vermeulen, Liew & Schilthuizen, 2015 from Malaysia is the only morphologically similar species with a tooth on the parietal lip, but it differs from the new species in having a tooth on the columellar lip as well as other shell characters. A checklist is also given for all the described Diplommatina species from North East India, as well as those from Darjeeling, West Bengal. http://www.zoobank.org/lsid:zoobank.org:act:0C252457-39A9-4451-AA24-8CA37F0A6271

印度东北部锡金-喜马拉雅半岛Diplommatina Benson属陆蜗牛一新种，1849（腹足目，软体动物目，Diplommatinidae）

摘要根据壳的形态描述了印度东北部锡金的一新种Diplommatina Benson，1849。这一新物种被发现在其外部可见的大顶齿和壳孔上没有小柱齿的情况下是不同的。提供了与新物种最接近的同源物的详细比较。来自马来西亚的Diplommatina bidentata Vermeulen，Liew&Schilthuizen，2015是唯一一个在顶唇上有牙齿的形态相似物种，但它与新物种的不同之处在于在柱唇上有一颗牙齿以及其他外壳特征。此外，还列出了来自印度东北部以及西孟加拉邦大吉岭的所有描述的Diplommatina物种的清单。http://www.zoobank.org/lsid:zoobank.org:act:0C252457-39A9-4451-AA24-8CA37F0A6271

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.
