Abstract
Two new and one known species of the genus Brevitobrilus, Epitobrilus setosus, Tripyla glomerans, and Ironus ignavus and I. sphincterus are described from sediments of LakesShala, Tana and Ziway, and River Abbay, Ethiopia. Brevitobrilus fesehai n. sp. can be recognized by acombination of characteristics: in having a narrowanterior end, short cephalic and outer labial setae,long and bow-shaped spicules, the posteriormostsupplement at a distance of less than a spicule lengthfrom cloacal opening, numerous micropapillae, andterminal and subterminal setae. B. tsalolikhinin.sp. can also easily be differentiated from allknown species in the genus in having a combination ofcharacteristics: long cephalic and outer labial setae,short spicules without median stiffening piece, theposteriormost supplement situated very close to thecloacal opening, supplements with straight duct thatmerges with the dorsal wall of the ampulla, andelongate spermatozoa. The remaining five species aredescribed in detail. Also scanning electronmicroscopic pictures of B. fesehai n.sp., B. tsalolikhini n.sp., Epitobrilus setosus andTripyla glomerans are presented.
