Gastrostyla steinii was found to have 4-8 macronuclei and thus its congener, G. muscorum which was characterized by eight macronuclei is likely a synonym with G. steinii. Redescriptions on Hemiamphisiella granulifera, Urostyla grandis Ehrenberg, 1830 and Nudiamphisiella interrupta, revealed that Saudi Arabia populations were morphologically identical with previous studies. A Nudiamphisiella species which is quite similar with N. illuvialis was also discussed. The abovementioned species show first show in Saudi Arabia and extend the known distribution areas of these species.} }
