Abstract :Pliovitellaria osteobramensis a Caryophyllaeid cestode was for the first time reported by Gupta & Sinha in 1984 from the intestine of Osteobrama- cotio (Ham) at Lucknow. Unfortunately Hafeezullah (1993)4 transferred this species under the genus Paracaryophyllaeus Kulakovaskaya (1961)5 on the ground that in P.osteobramensis :(i) Male and female genital pores are separate (not monogonoporate), (ii) External seminal vesicle is absent, (iii) Uterus extends almost to anterior level of cirrus sac, (iv) the testes commence from a level much behind anterior level of vitellaria and (v) absence of single bothrium on scolex ( all these he concluded by seeing the camera lucida drawing of P.osteobramensis given by Gupta & Sinha (1984)3 published in Ind.Jour.Helminth. Vol.XXXvi(i) : 73-80. Another species reported from India under the genus Paracaryophyllaeus is P.lepidocephali by Kundu (1985)6 which was recovered from the intestine of Lepidocephalichthys guntea (Hamilton) belonging to Cypriniformes : Cobitidae, reported from Garapota and Canning town, West Bengal- according to Hafeezullah (1993)4 although P.lepidoecephali was originally described under the genus Lytocestoides by Kundu (1985)6. The authors have valid reasons to restore the original status of Pliovitellaria osteobramensis Gupta & Sinha (1984)3 on scientific grounds .
