Rarnagiri, West Coast of Maharashtra, India. New species Tetragonocephlum suryajii Sp.Nov. comes closer to all known species of the genus Tetragonocephalum in general topography of organ but differs due to having size of worm 42-45 in length and 0.63 in width. The scolex is globular anteriorly and cushion like posteriorly, neck broader than long, mature proglottids three to four times broader than long, testes 55-65 in numbers, genital pores oval, sub-marginal, irregularly alternate, vagina posterior to cirrus pouch, ovary ‘U’ or ‘W’ shaped with many acini, vitellaria granular, gravid proglottids two to three times longer than broad and uterus sacular.
