A new and rare species of Cathetocephalus was collected from the spiral valve of bull shark, Carcharhinus leucas (Valenciennes, 1839) at Visakhapatnam coast. Four parasites were obtained from the host, and were characterized by the presence of characteristic and unique v-shaped scolex with the two arms drawn into thin, narrow and slender ribbon-like structures at the tips. This feature of scolex separates these parasites from the already reported species of the genus, C. thatcheri Dailey and Overstreet, 1973; C. australis Schmidt and Beveridge, 1990 and C. limbatus Pramanik and Manna, 2006. The present specie is named as Cathetocephalus leucas.
