Laimydorus ritae n. sp. is identified by its short odontostyle (16-18 mu m), a value of 1.4 for the ratio 'odontostyle L/lip region width', a lip region offset by depression, an anteriorly situated longitudinal vulva, females with long tail (328-392 mu m), non-hamate terminus and presence of males. Detailed descriptions of the remaining five species with scanning electron microscopic pictures of L. pseudostagnalis are also provided. I. ugandanus is reported here for the first time out of its type locality, Uganda.1 aAbebe, E.1 aCoomans, A.  uhttps://nematodes.myspecies.info/node/24601694nas a2200157   4500008004100000020001400041245014300055210006900198260000800267300001000275490000800285520116700293100001401460700001601474856004601490       1997                        eng d  a0018-815800aAquatic nematodes from Ethiopia .8.

Brevitobrilus fesehai n. sp. can be recognized by a combination of characteristics: in having a narrow anterior end, short cephalic and outer labial setae, long and bow-shaped spicules, the posteriormost supplement at a distance of less than a spicule length from cloacal opening, numerous micropapillae, and terminal and subterminal setae. B. tsalolikhini n.sp. can also easily be differentiated from all known species in the genus in having a combination of characteristics: long cephalic and outer labial setae, short spicules without median stiffening piece, the posteriormost supplement situated very close to the cloacal opening, supplements with straight duct that merges with the dorsal wall of the ampulla, and elongate spermatozoa. The remaining five species are described in detail. Also scanning electron microscopic pictures of B. fesehai n.sp., B. tsalolikhini n.sp., Epitobrilus setosus and Tripyla glomerans are presented.1 aAbebe, E.1 aCoomans, A.  uhttps://nematodes.myspecies.info/node/247
