Abstract EN
A new endoparasitic Turbellarian “Syndesmis obhoriensis" nov.
sp.
was collected for the first time from the coelomic cavity of the sea-urchin Echinothrix diadema.
The host was living in the shallow water of Obhor Creek, north Jeddah (Red Sea) on the sandy bottom from a depth varying from 3 to 5 meters.
It is related to the family Umagilleidae and the genus Syndesmis.
The worm is considered to be a new species for the following main reasons : 1.The worm is cylindrical in shape, pale white in color and its length reaches about 4 mm.
2.The intestine is saccate having a syncytial structure.
3.The epidermal layer is syncytial in structure.
4.The uterus extends anteriorly from the female antrum and ends a little distance after the vitallaria and its anterior end is attached to the oval egg capsule, continued posteriorly as a long much coiled multi-filamenton whip in the form of 8.
5.The vitellaria have six finger-like branches on each side.
6.Cement gland cells are fully occupying the last third part of the body.
7.Seminal vesicle is rounded.
