Six soil hypotrichous ciliates belonging to five genera and three families were morphologically investigated using non-flooded Petri dish method, live observation and protargol impregnation techniques. These organisms are: Urosomoida dorsiincisura Foissner, 1982, Urosoma emarginata (Stokes, 1885) Berger, 1999, Deviata brasiliensis Siqueira-Castro, Paiva & Silva-Neto, 2009, Gonostomum strenuum (Engelmann, 1862) Sterki, 1878, Gonostomum strenuum (Engelmann, 1862) Sterki, 1878, Gonostomum gonostomoidum (Hemberger, 1985) Berger, 1999, Wallackia bujoreani (Lepsi, 1951) Berger & Foissner, 1989 (Fig. 1, 2). Among them, Urosoma emarginata and Gonostomum gonostomoidum were first recorded in China. Deviata brasiliensis were first recorded from soil in China. The result showed that these populations differ slightly from historic populations, but they fluctuated within a narrow range. According to the results of cilium arrangement acquired by the adoption of protargol impregnation techniques, main taxonomic characteristics were measured and statistically analyzed, and the minimum values, maximum values, mean values, standard deviations and variation coefficients of main characteristics were calculated in all populations (Table 1﹣3). The results showed that the populations of every species investigated in this paper were slightly different from the same populations residing domestically and abroad. However, changes in these populations generally fluctuated within intra-species ranges. Therefore, this paper can enrich both species diversity of ciliates in China and researches concerning the geographical distribution of these ciliates populations.
