中文摘要：

昆虫贮精囊和精子的形态多样性是重要的分类和系统发育分析特征之一， 然而在马蜂亚科乃至整个胡蜂科中却鲜有涉及。本文首次解剖了角马蜂Polistes chinensis antennalis Pérez的雄性生殖系统， 着重对其贮精囊的超微结构进行描述， 并简要报道了精子的外部形态。角马蜂的贮精囊由输精管亚前端膨大而成， 有一层发达的柱状上皮细胞贴在基底膜内壁： 细胞核位于柱状细胞基部， 上皮细胞端半部线粒体密集， 顶膜特化成微绒毛。角马蜂精子头长21.4 μm， 体长94 μm， 是已报道胡蜂科精子中长度最短、 相对头长最长的种类。研究结果为胡蜂科昆虫系统发育以及繁殖生理提供理论依据。

英文摘要：

Morphological diversity of seminal vesicles and spermatozoa play an important role in the taxonomic and phylogenetic analysis, but it has been scarcely studied in the subfamily Polistinae, even in the whole Vespidae. The male reproductive system of the paper wasp Polistes chinensis antennalis Pérez was dissected for the first time, with emphasis on the ultrastructure of the seminal vesicle. The morphology of the sperm was also briefly reported. Seminal vesicle and accessory gland are not surrounded by a common sheath. The epithelium of seminal vesicle consists of a monolayer of cubical cells, adhering to a thick basal lamina, and these epithelial cells are polarized： the apical half of the epithelial cells is especially rich in mitochondria with the apical membrane being differentiated into microvilli, while the basal half contains the usual cellular organelles, including some mitochondria, the nucleus and prominent inclusions. The spermatozoa of P. chinensis antennalis are about 94 μm in length with the head about 21.4 μm in length, so it is the species with the shortest sperm and the longest relative head length of sperm described for the family Vespidae. The results may provide a theoretical foundation for phylogenetic analysis and reproductive physiology of Vespidae.
