Abstract

In this paper, the genus MicrodynerusThomson 1874 is newly recorded from China with one species Microdynerus (Pseudomicrodynerus) parvulus (Herrich-Schäeffer, 1838). Furthermore, a total of ten species of the genus Leptochilus de Saussure is recorded from China, including one new species, i.e., Leptochilus (Lionotulus) angulussp. nov., which is described and illustrated in detail. Of the remaining nine Leptochilus species three are recorded here for the first time from China, i.e., L. (Lionotulus) argentifrons (Kostylev, 1935), L. (Lionotulus) callidus (Kostylev, 1940), and L. (Lionotulus) locuples Giordani Soika, 1970, whereas the remaining six species, i.e., L. (Lionotulus) chinensis Gusenleitner, 2001, L. (Lionotulus) gobicus (Kostylev, 1940), L. (Lionotulus) habyrganus Kurzenko, 1977, L. (Lionotulus) incertus (Kostylev, 1940), L. (Lionotulus) kozlovi Kurzenko, 1977, and L. (Neoleptochilus) tibetanus Giordani Soika, 1966, have been documented from China before. All treated species are diagnosed and illustrated. Finally, a key to the Chinese species of the two related genera is provided.
