Nemacheilus ruppelli, also known as the mongoose loach is a species of fish in the genus Nemacheilus. This fish is endemic to the Western Ghats of India. Recent evidence shows that there is only a marginal raw mitochondrial genetic distance between Nemachilichthys shimogensis and N. ruppelli. Although morphometric difference occur at the population level, Keskar et al. conclude that there are no significant differences separating the two species. Therefore they treat N. shimogensis as a synonym of N. ruppelli. The Eschmeyer's Catalog of Fishes follows this treatment.
