A new species of gravel-dwelling loach (Ostariophysi: Nemacheilidae) from the Nepalese Himalayan foothills

Turcinoemacheilus himalaya, new species, is described from the Koshi and Gandaki River basins of Nepal. The new species is distinguished from its hypothesised congener, Turcinoemacheilus kosswigi, from the Euphrates, Tigris and Karoun basins of the Middle East, by the presence of small scales on the posterior half of its body (v. absence of all scales), its shorter caudal peduncle (caudal peduncle length 12-15% standard length, L(S) v. 16-23), its shorter snout (snout length 28-36% head length, L(H) v. 40-49) and by features of its colour pattern, including the presence of small irregularly shaped dark grey markings over the lateral body surface. Turcinoemacheilus himalaya is known to date only from Nepal.
