A revision of the Chinese Stephanidae (Hymenoptera, Stephanoidea).

Stephanidae Leach, 1815 (Hymenoptera: Stephanoidea) from China are revised. Five genera are reported from China: Foenatopus Smith, 1861; Megischus Brullé, 1846; Parastephanellus Enderlein, 1906; Schlettererius Ashmead, 1900; and Stephanus Jurine (in Panzer), 1801, and the genera are keyed. All the Chinese species are described and illustrated and new synonyms are established. Keys to species of the five genera occurring in China and adjacent regions are provided. Six species are new to science: Foenatopus brevimaculatus sp. n., F. maculiferus sp. n., F. yangi sp. n., Parastephanellus angulatus sp. n., P. brevicoxalis sp. n. and P. zhejiangensis sp. n. One species, Parastephanellus matsumotoi van Achterberg, 2006, is newly recorded from China. The following 9 new synonyms are proposed: Foenatopus aratifrons Enderlein, 1913 and F. yunnanensis Chao, 1964, new synonymys for F. annulitarsus Enderlein, 1913; F. cerviculatus (Chao, 1964) and F. chaoi Belokobylskij, 1995 for F. chinensis (Elliott, 1919); F. formosanus Enderlein, 1913 for F. cinctus (Matsumura, 1912); F. simillimus (Elliott, 1920) and F. trilineatus (Elliott, 1920) for F. flavidentatus (Enderlein, 1913); F. trilobatus (Elliott, 1920) for F. ruficollis (Enderlein, 1913); Parastephanellus austrochinensis Belokobylskij, 1995 for P. brevistigma Enderlein, 1913. A lectotype is designated for Diastephanus trilineatus Elliott, 1920 [ABSTRACT FROM AUTHOR]
