笔者认为湖南节甲茧蜂ＳｉｇａｌｐｈｕｓｈｕｎａｎｕｓＹｏｕｅｔＴｏｎｇ仍为有效的独立种，不同意ｖａｎＡｃｈｔｅｒｂｅｒｇ和Ａｕｓｔｉｎ（１９９２）认为湖南节甲茧蜂和棉小造桥虫节甲茧蜂Ｓ．ａｎｏｍｉｄｓＹｏｕｅｔＺｈｏｕ均为列齿节甲茧蜂Ｓ．ｉｒｒｏｒａｔｏｒ（Ｆａｂｒｉｃｉｕｓ）的新异名的看法．棉小造桥虫节甲茧蜂和湖南节甲茧蜂是否同种，存疑．
The genus Sigalphus Latreille,1802 is a small genus with four species in China.There are Sigalphus hunanus You et Tong,S.anomis You et Zhou,S.flavistigmus He et Chen and S.nigripes He et Chen. The genera of subfamily sigalphinae and Australian species are cur-rently under revision by C.van Achterberg and A.D.Austin. They suggested that Sigalphus hunanus You et Tong and S.anomis you et Zhou be a synonyms of S.irrorator(Fabricius).After further detailled study of S.irrorator (Fabricius) kept in the Brit.Mus.(Nat.Hist.)London(The examined material were:♀,B.M.1935-271,K.von Stein Coll.Det.J.A.J.Clark, 1966;♀,B.M. 59-101,R.von Stein Coll.,S.irrorator Feb.;♀,B.M.1935-271,R.von Stein Coll.S. irrorator Fabricius, Det.Limon;♀,Germany,59-101,S.irrorator Fabri-cius;♀,Germany, 59-101, Ruthe Coll.;other two specimens have not collect record),we recognized that the Sigalphus hunanus You et Tong is still a valid species. Our specimen is similar to S.irrorator(Fabricius),but there is a large discrepancy in the structure of the face, propodeum,lst metasomal tergite and colour of hind tibia. For correct identification of this species,careness should be taken with regard as follows.Whether Sigalphus hunanus You et Tong and S.anomis You et Zhou is the same species or not,it needs further study.We would like to thank Dr.Donald L.J.Quicke for providing specimens of Sigalphus irrorator(Fabricius)kept in Brit.Mus.(Nat. Hist)in this study.
