Abstract / Notes
"This worm was collected from a stagnant freshwater pond near a village called " El Halaby " 10 Kilometers far away from the west side of Zagazig University at Sharkia Province in Nile Delta". It lives upon the aquatic vegetation including Eichhornia crassipes and Elodea canadensis. The salinity of water was 2.5% and 29 C. The worm is oval in shape with a blunt anterior end and a broad posterior end. It has a length of l-2mm. Its coloration is pale white. It has a pair of kidney-shaped brownish black eyes, situated a little distance in front of the mouth aperture. This worm is characterized from the other known species of the genus Macrostomum by a chitinised penis-stylet which is curved in two planes. Its distal end is enlarged and slightly thickened and has a terminal aperture."
