摘要: 本文记述中国平背叶蜂亚科二新属新种:扁角隙臀叶蜂Blennallantus compressicornis gen.et sp. nov.,红胸宽背叶蜂Allanempria rufithoracica gen.et sp. nov.。隙臀叶蜂属Blennallantus gen. Nov.形态十分特殊:唇基三齿型;颚眼距长于单眼直径2倍,上颚对称双齿型;后颊脊全缘式;触角侧扁,10节,基部2节宽显著大于长;爪简单,无内齿和基片;前胸侧板腹面尖,互相远离;后胸 后背板长且平;前翅基臀室端部中断,2A+3A脉长;后翅Rs室开放,M室封闭等可与叶蜂科已知各属相区别。宽背叶蜂属Allanempria gen. Nov.与史氏叶蜂属Dasmithius Xiao近似,但后翅臀室无柄式,中胸后背板长,中部不收缩,后眶沟显著,复眼间距等于眼高,颚眼距狭窄,锯腹片无叶状刺毛等,可与之区别。模式标本保存于中南林学院环境与资源系昆虫标本室。Abstract: In this paper two new genera and two new species of Empriini,Allantinae from China are described:Blennallantus compressicornis gen.Et sp.nov.,Allanempria rufithoracica gen.Et sp.nov.The type specimens are deposited in the Insect Collection of the Central South Forestry University.
