描述了喜马拉雅山东部的一种新的食螺蛇，属Pareas Wagler，1830。Pareas kaduri sp. nov.与该属所有已知种的不同之处在于具有以下一系列特征：SVL 455-550 mm，TaL/TL 0.184-0.207，背褐色，全身有黑色横带，全身有15个背鳞列，背中部脊椎鳞列增大，雄性有8列龙骨状，齿膜不接触眼眶，腹侧160-183，尾下65-70雄性，52雌性标本，半阴茎短，单裂和6-7上颌齿。线粒体16 S rRNA和细胞色素B基因的分子数据进一步证明了该新物种的独特性，该物种被发现为帕雷斯汉普顿进化枝的一员。我们的工作使属Pareas内确认的物种总数达到20个。
A new species of snail-eating snakes of the genus Pareas Wagler, 1830 is described from the eastern Himalayas. The species Pareas kaduri sp. nov. differs from all known species of the genus in bearing the following suite of characters: SVL 455-550 mm, TaL/TL 0.184-0.207, brown dorsum with black transverse bands throughout the body, 15 dorsal scale rows throughout the body and mid-dorsal vertebral scale rows enlarged, 8 rows keeled in males, loreal not touching orbit, ventrals 160-183, subcaudals 65-70 in males, 52 in one female specimen, hemipenis short, unilobed and 6-7 maxillary teeth. Molecular data for mitochondrial 16S rRNA and cytochrome b genes further attest the distinctness of the new species, which was recovered as a member of the Pareas hamptoni clade. Our work brings the total number of species recognized within the genus Pareas to 20.
