Abstract

The present investigation deals with the morpho-taxonomic observation of Pseudophyllidean tapeworm Senga satarensis Sp.Nov. collected from intestine of a Mastacembelus armatus at various places of Satara districts of (M.S.) India. The worm comes closer to all the known species of this genus in general topography of organ but differs due to scolex pear shaped, tapering anteriorly and broad posteriorly, rostellum medium, rounded, bearing 28-30 rostellar hooks, neck absent, mature proglottids six to seven times broader than long, testes 175-200 in numbers, scattered throughout the segment, cirrus pouch oval, ovary distinctly bilobed, vagina thin, runs posteriorly, genital pores oval in shape, vitellaria granular, uterus saccular and egg elongated.
