New records of Porrocaecum sp. and Hysterothylacium sp. (Nematoda: Anisakidae) from fishes of Bay of Bengal

The present paper deals with new records of nematoda of the family Anisakidae Railliet et Henry, 1912. During a study of the parasites of marine fishes (shark, ray and marine teleosts) of Bay of Bengal, females of interesting nematode parasites were found in stomach and body cavity of Chiloscyllium indicum (Gmelin), Torpedo panthera (Olfers), Pomadasys masculatus Bloch and Sphyraena obtusata Cuvier from Visakhapatnam, Bheemunipatnam and Yarada (Andhra Pradesh). Most of the characters tally with Porrocaecum galeocerdonis and Hysterothylacium engraulisi, except for minor variations. Because of the non-availability of the male, it is not possible to assign the present specimens to any of the known species of the genera Porrocaecum and Hysterothylacium. Hence these are referred as Porrocaecum sp. and Hysterothylacium sp. Chiloscyllium indicum and Torpedo panthera are new host records. Visakhapatnam, Bheemunipatnam and Yarada are the new locality records.
