Taxonomy And Comparative Morphology Study Of The Subfamily Pachygastricidae In China

The paper is a traditional taxonomic and comparative morphological study on the Pachygastrinae?Diptera:Brachycera:Stratiomyidae?of China,According to the specimens and literature,27 genera and 89 species of Pachygastrinae were systematically arranged.The main contents of the research results as follows:a new recorded genus of Pachygastrinae from China:Maackiana Krivosheina,1973,and three new recorded species:Abrosiomyia bella Nagatomi,1975,Gabaza nigrotibialis?Pleske,1930?and Parastratiosphecomyia freidbergi Woodley,2012,were described?female of P.freidbergi was firstly described?.16 new species from China:Abiomyia flavipes sp.nov.;A.nigrifemura sp.nov;A.pseudonigrifemura sp.nov.;Camptopteromyia hainanensis sp.nov.;Camptopter-omyia yunnanensis sp.nov.;Evaza pseudojavanensis sp.nov.;Maackiana guizhoue-nsis sp.nov.;M.hainanensis sp.nov.;M.lishanensis sp.nov.;M.sichuanensis sp.nov.;Monacanthomyia guizhouensis sp.nov.;Pseudomeristomerinx flaviscutelluma sp.nov.;P.yunnanensis sp.nov.;Rosapha hainanensis sp.nov.;R.tristripesis sp.nov.;and R.gaoligonga sp.nov.were recorded,described and illustrated.Abiomyia annulipes Kertész,1914;Craspedometopon frontale Kertész,1909;C.spina Yang,Wei et Yang,2010;Evaza flavimarginata Zhang et Yang,2010;E.nigritibia Chen,Zhang et Yang,2010;E.ravitibia Chen,Zhang et Yang,2010;Gabaza sinica?Lindner,1940?;Kolomania albopolosa?Nagatomi,1975?;Nasimyia elongoverpa Yang et Hauser,2013;N.eurytarsa Yang et Hauser,2013;N.megacephala Yang et Yang,2010;N.rozksonyi Yang et Hauser,2013;Parastratiosphecomyia szechuanensis Lindner,1954;P.rozkosnyi Woodley,2012;Pseudomeristomerinx nigromaculatus Yang,Zhang et Li,2014;Rosapha bimaculata Wulp,1904;Tinda javana?Macquart,1938?;T.indica?Walker,1851?were re-describedThrough the comparative morphological study of external features,the generic characters of each genus were compared,and the important generic characters of Cucla in the vein was obtained:The R₂₊₃+3 vein was fused with it in the middle of R₁vein.Identification keys to genus and species was compiled.Through comparative morphological study on the female genitalia found that the differences in female genitalia were stable and distinct between species,and these differences could be used as a complement to the identification of male genitalia.These differences are unstable in the genus,and cannot be promoted to the generic character.Only the genus can be roughly classified.A phylogenetic analysis based on morphological data was performed on the Pachygastrinae,and the relationship among the genus was analyzed.
