A new Thalassomonhystera species, i.e. T traesti n.sp., and a new subspecies, Monhystrella lepidura chinensis n. subsp., together with Emnonhystera andrassyi (Biro, 1969) Andrassy, 1981, Monhystrella macrura (de Man, 1880) Andrassy, 1981 and Monhystrella iranica Schiemer, 1965 are described from Li River at Guiling, China. Thalassomonhystera traesti n.sp. is characterised by a combination of the following characters: expanded lip region, large and anteriorly situated amphids, prominent inner labial sensilla, and slender spicules and tube-like gubernaculum in males. Monhystrella lepidura chinensis n. subsp. belongs to Monhystrella lepidura (Andrassy, 1963) Andrassy, 1968 but differs from the three hitherto described subspecies in its possession of a pharynx that posteriorly expands into a double bulb. Monhystrella macrura, M. iranica and Eumonhystera andrassyi are reported here for the first time from China.
