| 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. |
