Two new species of the uropeltid snake genus Rhinophis Hemprich, 1820 are described from Sri Lanka. Rhinophis martin sp. nov. is described from 11 type specimens from the Rakwana Massif, and another 22 specimens from the same region are referred to this new species. Rhinophis dinarzardae sp. nov. is described from eight type specimens from the Knuckles Massif, and another 64 specimens from the Knuckles and adjacent hills are referred to this new species. Rhinophis martin sp. nov. has apparently not been reported previously under any scientific name, but is distinct in scalation, colour pattern and DNA. Rhinophis dinarzardae sp. nov. has long-been confused with the superficially similar R. philippinus, from which it differs by having more ventral scales, by occurring in the northern part of the Knuckles Massif and adjacent hills to the West rather than in the Central Highlands upland region (and possibly areas to the South and West) of Sri Lanka, and in DNA sequence data. The new descriptions take the inventory of currently recognised, named uropeltid species in Sri Lanka to 20, all members of the genus Rhinophis.
本文描述了来自斯里兰卡的两种新的食蚣属（Rhinophis Hemprich，1820）蛇类。马丁食蚣（Rhinophis martin sp. nov.）依据来自拉夸纳地块的11个模式标本进行描述，另有来自同一地区的22个标本也归为该新物种。迪纳尔扎德食蚣（Rhinophis dinarzardae sp. nov.）依据来自努克尔斯地块的8个模式标本进行描述，另有来自努克尔斯及邻近山区的64个标本也归为该新物种。马丁食蚣（Rhinophis martin sp. nov.）此前显然未以任何科学名称被报道过，但在鳞片、色斑和DNA方面具有独特性。迪纳尔扎德食蚣（Rhinophis dinarzardae sp. nov.）长期以来一直与外观相似的菲律宾食蚣（R. philippinus）混淆，它与之不同之处在于腹鳞更多，分布于努克尔斯地块北部及西部邻近山区，而非斯里兰卡的中央高地地区（以及可能的南部和西部地区），并且在DNA序列数据上也有差异。这些新描述使斯里兰卡目前已确认命名的食蚣属蛇类物种名录增加到20种。
