Revision of the genus Lepidopria Kieffer (Hymenoptera, Diapriidae, Diapriinae) of the world fauna

All known species of the diapriid genus Lepidopria Kieffer, 1911 are revised, keyed and illustrated. A new species, L. bicarinata Chemyreva & Ku, sp. nov. is described from South Korea. The diagnosis of the genus Lepidopria, as well as that of all described species, has been clarified.

New data on the distribution of the species L. masneri Notton, 1994 and L. pedestris Kieffer, 1911 are provided. The association of L. masneri with the nests of Solenopsis japonica Wheeler, 1928 is reported and the biology of Lepidopria species is discussed. Taxonomic status of the mysterious L. aberrans Brues, 1916 is considered and a new combination, Bruesopria aberrans (Brues), comb. nov., suggested.
