AB  - The morphology and infraciliature of five soil hypotrichous collected from the farm-land at Zulfi city, Saudi Arabia were investigated using living observation and silver impregnation methods.<I> Gastrostyla steinii</I> was found to have 4-8 macronuclei and thus its congener, <I>G. muscorum</I> which was characterized by eight macronuclei is likely a synonym with <I> G. steinii</I>. Redescriptions on <I> Hemiamphisiella granulifera</I>,<I> Urostyla grandis</I> Ehrenberg, 1830 and <I>Nudiamphisiella interrupta</I>, revealed that Saudi Arabia populations were morphologically identical with previous studies. A <I>Nudiamphisiella</I> species which is quite similar with <I>N. illuvialis</I> was also discussed. The abovementioned species show first show in Saudi Arabia and extend the known distribution areas of these species.
