Mesonoemacheilus menoni is a species of ray-finned fish in the genus Mesonoemacheilus. It is endemic to the southern Western Ghats in Kerala, India, where it occurs in the upper reaches of the Periyar River over substrates of cobbles, pebbles and sand in flowing water. It is common within the Periyar Tiger Reserve but may be threatened by predation and competition from the invasive African cichlid Mozambique tilapia, the common carp and Clarias gariepinus.
Nemacheilus monilis, the spotted loach, is a species of ray-finned fish in the genus Nemacheilus which is endemic to the southern Western Ghats in the Indian states of Kerala and Tamil Nadu.

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.
Nemacheilus stigmofasciatus, the Thuttinjet stone loach, is a species of ray-finned fish in the genus Nemacheilus which has been recorded from just one locality in the west flowing river Seethanathi at Thuttinjet in Karnataka.
