中国凹胸姬小蜂属研究(膜翅目:姬小蜂科)

研究了中国的1新记录属，凹胸姬小蜂Alophomorphella Girault。该属原来只分布在澳大利亚，其分类学位置及其和姬小蜂亚科和其它属的关系并不明确。有些研究人员认为它属于狭面姬小蜂属Elachertus Spinola。通过扫描电镜观察和比较外部形态学研究，作者发现该属具有下列稳定的性状：1）中胸小盾片上有一条纵沟；2）前胸侧板腹面上有一对对称的斜沟。因此确认该属为姬小蜂科中一个特殊属，它和Elachertus之间没有非常近的亲缘关系。本文重新描述了A.illustris Girault的雌性，并首次描述了该种的雄性。

A STUDY ON ALOPHOMORPHELLA GIRAULT IN CHINA (HYMENOPTERA: EULOPHIDAE)

This paper treats Alophomorphella Girault newly recorded from China. The genus was reported to occur only in Australia and its status and relationships with other genera in Eulophidae are not clear. Some workers wonder if it is one form in Elachertus Spinola. With Scanning Electronic Microscope and comparative morphology, we found this genus could be re-defined by following stable characters: 1) a longitudinal pit is present on middle of scutellum; 2) one pair of inverted fork-like grooves is present on ventral part of propleuron. This study found this genus a very unique one and revealed no close relationships between this genus and Elachertus Spinola. Female of A. illustris Girault is re-described and male is described for the first time.
