Summary:Keywords: Key Words: Paramphistomum alykhani n.sp., trematode, goat, Karachi, Pakistan Introduction The family Paramphistomidae Fischoeder, 1901 is closely related to Fasciolidae in the life cycle pattern as the second intermediate host is not needed, but unlike in morphology of adult. Gigantocotyle Näsmark, 1937 with significant characters such as body conical pyriform, nearly round in cross section, without ventral pouch, acetabulum ventro terminal or practically ventral, acetabular index very variable, ovary post testicular, vitellaria extending in lateral fields, testes rounded or lobate, tandem somewhat diagonal, genital calyx, genital sucker and pars musculosa poorly developed or absent and parasites in bile duct, stomach or intestine of mammals. Eggs are released with mammal faeces, they later hatch into miracidia which enter the body of intermediate host, which are snail, then the miracidia loose their cilia to become sporocysts. The present specimens differ from the closest species P. cervi (Zedar, 1790) Fischoeder, 1901 in general shape of body and testes and in having much smaller ovary also vitellaria do not reach posterior end; while P.explanatum Creplin, 1847 besides general shape of body has testis touching each other and are not round and has an oval ovary near to the posterior testis and vitellaria do not reach posterior end of the body .The name of the species is in honour of Dr. Aly Khan Ex- Director CDRI (Pakistan Agriculture Research Council) University of Karachi, Karachi-75270 for his contribution in the field of Parasitology.
