本文报道了星豹蛛精子发生和精子的超微结构。该物种的精子发生与其他蜘蛛有一些共同的特征。但在所研究的物种中也有一些新的发现，主要是：1）在精巢、精原细胞和精囊周围出现了外上皮细胞; 2）（3）成熟精子细胞核周围有微管，细胞膜下有微管，成熟精子无微管;（4）无鞭毛通道和线粒体，但有一些致密的空泡和一个大的池;（5）顶体空泡呈锥形，部分嵌入核内;（6）精子包装方式为闭精。
Spermatogenesis and ultrastructure of spermatozoon of Pardosa astrigera, a wolf spider, are described. The spermatogenesis of the species shares some characteristics with other spiders. But there are some new data in the species studied, mainly; 1) the occurrence of outer epithelial cell around the testis, spermatogoniunl and spermalocyyle; 2) (luring the spermiogenesis two centrioles lying parallel to each other early but perpendicularly later; 3 ) a microlubular manchette around the nucleus but under the cell membrane later, and no microtubule in mature sperm; 4) no flagellar tunnel and mitochondria but with some dense vacuoles and a large cisterna; 5) acrosomal vacuole cone-shaped and embedded partly in the nucleus; and 6) a sperm packaging pattern of cleistospermia.
