Abstract:
A new species of the genus Tubulovesicula Yamaguti, 1934 is described here and named T. olivaceus from the stomach of the fish Pomadasys olivaceum (Pomadasyidae) off Karachi coast. The new species is separated from the previously described species as it has relatively small tail or ecsoma, ventral sucker at least 3 times larger than the oral sucker, testes close to ventral sucker, seminal vesicle pre-testicular, long, broader posteriorly reaching to posterior border of ventral sucker, pars prostatica small, hermaphroditic duct enclosed in a small, muscular pouch, genital opening at the base of pharynx immediately behind the intestinal bifurcate. Ovary is in the middle of soma, seven, coiled vitelline tubules situated almost in the middle of soma, uterus long, terminating far anterior to ecsoma. Eggs are numerous, small. Excretory pore is terminal. Excretory vesicle is tubular, arms uniting dorsal to pharynx.
