Abstract
Triplophysa waisihani, a new species of nemacheiline loach, is described from the Kax River, a tributary of the Ili River drainage in Xinjiang-Uighur Autonomous Region of Northwest China. It can be assigned to the T. labiata species group characterized by having widely separated anterior and posterior nostrils and no breeding tubercles on the sides of the head. Triplophysa waisihani resembles T. labiata and T. herzensteini, but differs from both in cephalic sensory-canal pattern and the structure of the gas bladder; from T. labiata in the structure of the pelvic girdle and absence or presence of the fourth basibranchial; and from T. herzensteini in the shape of the anal fin.References
