蔺叶蜂亚科一新属新种（膜翅目：叶蜂科）

A NEW GENUS OF BLENNOCAMPINAE FROM TIBET,CHINA(HYM:Tenthredinidae)

本文记述蔺叶蜂亚科１新属新种：朱氏背齿叶蜂Ｎｏｔｏｄｏｎｔｉｄｅａｃｈｕｉｇｅｎ．ｓｐ．ｎｏｖ新属隶属于等角叶蜂族Ｐｈｙｍａｔｏｃｅｒｉｎｉ，与窝眶叶蜂属ＲｈａｄｉｎｏｃｅｒａｅａＫｏｎｏｗ及扁室叶蜂属ＣｏｒｐｉｌｕｓＭａｌａｉｓｅ较近似；窝眶叶蜂属触角粗短且简单，第２节长等于宽，唇基截型，颚眼距狭于１／２单眼直径，后眶沟深并具陷窝，爪具微小内齿，前足胫节内距分叉等易于新属区别；扁室叶蜂属唇基截型，颚眼距线状，后眶沟较明显，触角窝间距狭于复眼一触角窝距，复眼大且长型，间距约等于眼高，触角简单并具触角器，具痕状胸腹侧片，小盾片附片极狭，后胸淡膜区间距等于淡膜区宽，前足胫节内距分叉，前翅第１盘室横宽型，第１肘室十分扁宽，第１回脉交于第２肘室中部外侧，第２回脉与第２肘横脉几乎相接，第３肘室等长于１＋２肘室之和，后翅臀室柄仅为后臀室１／２长等与新属区别较大。新属具背齿型触角，与蔺叶蜂亚科各属均不同。在简要讨论了新属与近源属的关系后，齿角叶蜂族ＣｅｒａｔｕｌｉｎｉＳｍｉｔｈ１９６９被降为等角叶蜂族Ｐｈｙｍａｔｏｃｅｒｉｎｉ的次异名。

Notodontidea,a new genus and N.chui,a new species,from Tibet are described and figured.Its phylogeny and the relationship with some genera of Blennocampinae are also briefly discussed.The tribe Ceratulini Smith 1969 is synonymized with Phymatocerini Rohwer 1911(=Ceratulini Smith 1969 syn.nov.).
