本文报道了印盲蝽科两栖动物一新种--高山隐盲蝽Hypotyphis montanus sp. nov.，根据2013年和2015年从两个地方收集的塞舌尔马埃岛的一系列标本进行描述。新物种最接近塞舌尔（马埃）特有的H。brevis在短（最大已知的总长度在生活ca。110毫米）和长吻，但不同的是有更多的椎骨，一个相对较小的头部，和基本上不同的线粒体和核基因序列。新种Hypotrophis montanus sp. nov.的分布海拔（718-731 m）比H. brevis（约）350-650米），其海拔限制分布在一个小岛屿上，可能使其受到IUCN红色名录标准的威胁。Hypoprophismontanussp. nov.是第三种在塞舌尔发现的小型长吻无尾目动物。沿着H. brevis和H. pti，H. montanus sp. nov.是已知的最小的无尾目种类之一，可能是全球分布最小的种类。
A new species of indotyphlid caecilian amphibian, Hypogeophis montanus sp. nov., is described based on a series of specimens from the Seychelles island of Mahé, collected from two localities in 2013 and 2015. The new species most closely resembles the Seychelles (Mahé) endemic H. brevis in being short (maximum known total length in life ca. 110 mm) and long snouted, but differs by having more vertebrae, a relatively smaller head, and substantially distinct mitochondrial and nuclear gene sequences. Hypogeophis montanus sp. nov. is known from higher elevations (718-731 m) than H. brevis (ca. 350-650 m), and its elevationally restricted distribution on a single small island likely renders it threatened under IUCN Red List criteria. Hypogeophis montanus sp. nov. is the third species of small and long-snouted caecilian reported from the Seychelles. Along with H. brevis and H. pti, H. montanus sp. nov. is among the smallest known species of caecilian and possibly has the smallest global distribution.
