Kalicephalus (Kalicephalus) costatus indicus (Ortlepp, 1923) Schad, 1962, recovered from the intestine of Asiatic water snake, Xenochropis piscator (Schneider, 1799), from the Suri town, Birbhum district of West Bengal, India, is redescribed. The nematode is characterised by presence of buccal capsule and well developed copulatory bursa. The buccal capsule consists of two lateral valves. Each valve is composed of four anterior plates, one posterior ventral plate and one posterior dorsal plate. Perioral groove in each valve is delimited by one anterior chitinoid ridge. Externally on each valve three parenchymatous bands lead to the circumoral papillae. Spicules are equal with finely pointed distal end. Posterior third of the spicules are provided with ala. Gubernaculum is lanceolate shaped. Birbhum district is recorded as new geographical locality for this parasite.
