A new nematode species, Pseudocapillaria indica sp. п., is described from the intestine of the freshwater fish Channa gachua (Hamilton) from Kerala, India. It resembles P. tomentosa (Dujardin, 1843), differing from it mainly in the structure of the proximal end of spicule, the shape and structure of the stichocytes and in having smaller eggs (size 0.036-0.048 x 0.023-0.027 mm) which have a different type of superficial structure. Pseudocapillaria indica is the first capillariid species described from freshwater fishes of India and from the whole Oriental Region.
