On a new Acanthocephalan Species of Pallisentis Van Cleave, 1928 Recovered from Intestine of Glossogobius giuris (Hamilton 1822) from River Gomti at Lucknow

The Acanthocephala represents a group of worms parasitic in gastrointestinal tract of all vertebrate groups especially in fish and birds. Acathocephalan of genus Pallisentis are intestinal parasites of fresh water fish. Subfamily Pallisentinae of order Gyracanthocephala includes four genera namely Acanthosentis Verma & Datta, 1929; Acanthogyrus Thaper, 1927; Pallisentis Van Cleave, 1928, and Raosentis Datta, 1947. Van Cleave (1928) established the genus Pallisentis with P. umbellatus as its type species. Pallisentis differs from all the above genera in having proboscis armed with 4 circles of 6-10 hooks each and presence of collar of spines arranged in 6-14 closely set rings near anterior extremity; posterior to this collar of spines is an unspined zone which is followed by widely spaced rings of spines.
