TWO NEW SPECIES OF THE GENUS OOMYZUS RONDANI(HYMENOPTERA:EULOPHIDAE:TETRASTICHINAE)

his paper describes two new species of Oomyzus Rondani.They are parasitic wasps of lacewing flies Chrysops septempunctata Wesmael and Ch.sinica Tjeder respectively from Hubei Province,China.The type specimens are preserved in Jiangxi Agricultural University.Oomyzus hubeiensis sp.nov. (Figs.14)♀.Body lendth 1011 mm,metallic bluish green.Antennal pedicel equal to the first funicle in length.Club as long as the preceeding 2 funicles and 1/2 of the first funicle combined.OOL about as long as 15 OD.POL as long as or slightly shorter than OOL.Median carinae of propodeum and paraspiracular carinae wanting..Body length 086 mm.Antennal funicle 4 segments,F 1 round,others are subequal in length and slightly longer than wide,flagellum with longer hairs.This new species resembles Tetrastichus chrysopae (Crawford),but its female propodeal spiracles uncontiguous with anterior margin of the sclerite;the antennal club unequal to funicle in length.Holotype ♀,paratypes 29♀♀,11,Danjiangkou (326°N,1113°E),Hubei Province,Apr.May,1974.ZHAO JingZhao.Host Chrysopa septempunctata Wesmael (pupa).Oomyzus sinensis sp.nov. (Figs.57)♀.Body length 12 mm.This new species is similar to O.hubeiensis sp.nov.,but the female propodeum with a median carina and the first funicular segment of the male antennae not rounded.Holotype ♀,paratypes 7♀♀,6,Tianmen (306°N,1131°E),Hubei Province,May,1977.ZHAO JingZhao.Host Chrysopa sinica Tjeder (pupa).
