Ombrana is a monotypic genus of frogs in the family Dicroglossidae. It is represented by a single species, Ombrana sikimensis. The validity of this genus is currently considered uncertain.[2]
Ombrana sikimensis is found in central and eastern Nepal and in parts of northeastern India (Sikkim, West Bengal, and Meghalaya). It may also occur in Bhutan.[3] It has been recorded at elevations between 1,000 and 2,000 m (3,300 and 6,600 ft) above sea level.[1]
