In this study, 639 of Allolobophora caliginosa were collected from different regions of Nile Delta of Egypt. Metaradiophrya egyptiaca n. sp. was recorded in intestinal worms from Bajour (Monoufia Governorate) only. Ciliate species ranged in size from 100-137μm (125.7±9.9μm) in length & 57-88μm (72.5±10.7) in width. Macronucleus is long, band-shape, varied between 71- 106μm (92.8±10.2μm) in length x 5.6-10.3μm (7.3±1.5μm) in width. Ciliate has 2 rows of contractile vacuoles on both side of macronucleus, each row of 4-6 vacuoles. There were 75-84 kineties on body dorsal side and 56-60 kineties on ventral one. The 58 ectoplasmic fibers restricted in anterior ventral depressed region, from which 12-13 ones end on ectoplasm left clear area and 9 fibers from distal end of the right shaft.
