Laimydorus ritae n. sp., Laimydoruspseudostagnalis, Dorylaimus stagnalis, Ischiodorylaimus ugandanus, Mononchus truncatusand Diploscapter coronatus are described fromsediment samples of Lake Tana, Ethiopia. Laimydorus ritae n. sp. is identified by its shortodontostyle (16-18 µm), a value of 4 for the ratio'odontostyle L/lip region width', a lip region offsetby depression, an anteriorly situated longitudinalvulva, females with long tail (328-392 µm),non-hamate terminus and presence of males. Detaileddescriptions of the remaining five species withscanning electron microscopic pictures of L.pseudostagnalis are also provided. I. ugandanusis reported here for the first time out of its typelocality, Uganda.[PUBLICATION ABSTRACT]
