The spermiogenesis and the sperm ultrastructure of several species of Coniopterygidae have been examined. The spermatozoa consist of a three-layered acrosome, an elongated elliptical nucleus, a long flagellum provided with a 9+9+3 axoneme and two mitochondrial derivatives. No accessory bodies were observed. The axoneme exhibits accessory microtubules provided with 13, rather than 16, protofilaments in their tubular wall; the intertubular material is reduced and distributed differently from that observed in other Neuropterida. Sperm axoneme organization supports the isolated position of the family previously proposed on the basis of morphological data.
对几种粉蛉科昆虫的精子发生过程和精子超微结构进行了研究。精子由三层顶体、一个细长的椭圆形细胞核、一条具有9+9+3轴丝的长鞭毛以及两个线粒体衍生物组成。未观察到附属体。轴丝的附属微管在其管壁中有13条原丝，而非16条；管间物质减少，且其分布与在其他脉翅目昆虫中观察到的不同。精子轴丝结构支持了此前根据形态学数据提出的该科独立的分类地位。
