简介
During examination of Little Cormorant Phalacrocorax niger for the presence of helminth parasites, a total of 105 trematodes belonging to genus Paryphostomum Dietz, 1909 were recovered from intestine of 5 hosts. These trematodes have large, elongated body, reniform head collar equipped with 22 spines, large acetabulum, oval cirrus sac, anterior testis tri-lobed, spherical ovary, broad uterus and prominent lateral vitellaria. These were compared with closely related species and found differing from their congeners in number and size of collar spines, acetabulum, uterus and eggs, shape of cirrus sac, position of ovary and position and shape of testes. On the basis of these diagnostic differences, a new species Paryphostomum sanghari is proposed to accommodate the present worm. Species name refers to the locality of host bird.
