Abstract

Historical, nomenclatural, technical, and biological problems associated with the 42 species of Mesothrips are discussed. Type specimens have been re-examined of 14 of the 25 species that were described prior to 1930 and remain known only from imperfectly slide-mounted specimens. As a result, seven new synonyms are recognised. From China, six species of Mesothrips have been listed, but the records of M.alluaudi and M.manii are rejected, and three new species are described: M.jianfengisp. nov., M.longistylussp. nov., and M.verniciasp. nov. These three species are divergent from other members of Mesothrips in lacking a prominent fore tarsal tooth and may indicate a possible generic relationship to the flower-living species in the Asian genus Dolichothrips. An illustrated key is provided to the seven Mesothrips species now known from China.

Keywords: Key; M.jianfengi; M.longistylus; M.vernicia; new species.
