New records of Porrocaecum sp. and Hysterothylacium sp. Nematoda: Anisakidae; from fishes of bay of bengal

El presente artículo trata de nuevos registros de nematodes de la familia Heterocheilidae Railliet y Henry, 1912. Durante un estudio de los parásitos de peces marinos (tiburón, raya y teleósteos) de la Bahía de Bengala, fueron observadas hembras de interesantes nematodes parásitos en el estómago y cavidad visceral de Chiloscyllium (Gmelin), Torpedo panthera (Olfers), Pomadasys maculatus (Bloch) y Sphyraena obtusata Cuvier de Visakhapatnam, Beheemunipatnam y Yarada (Andra Pradesh). La mayoría de sus características concuerdan con Porrocaecum galeocerdonie e Hysterothylacium engraulisi, pero difieren en variaciones mínimas. Debido a que no se dispuso del macho, no es posible clasificar los presentes ejemplares en ningula de las especies conocidas del género Porrocaecum y Hysterothylacium. Por lo tanto, deben ser referidas como Porrocaecum sp. y Hysterothylacium sp. Chiloscyllium indicum y Torpedo panthera son nuevos huéspedes registrados. Visakhapatnam, Bheemunipatnam y Yarada son las nuevas localidades registradas

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.
