A trematode parasite belonging to genus Anchitrema (LOOSS, 1899); was collected for the first time from the small intestine of the climbing rats (Rattus rattus) that were trapped from Edfina, Behera Province, Egypt. The general prevalence of infection with that parasite was about 7.5%. Full description of that fluke was given together with illustrated camera lucida drawings and microphotos. Although, the present material slightly differed from Anchitrema sanguineum described from other mammals particularly in the body length and egg sizes; yet these differences were considered of little taxonomic importance. Therefore, the present species could be identified as Anchitrema sanguineum (SONSINO, 1894).
