The spermatozoon of the Onychophoran Peripatoides leuckarti is described and compared with that of Peripatopsis previously investigated. The general shape of the cell is the same, with persisting typical characteristic of a manchette and of nine accessory tubules surrounding the axoneme. There is a difference in the mitochondrial derivatives, which are two and partially located in a nuclear posterior concavity. But the most significant finding is the presence of a thin, flat acrosome surrounding the nucleus, which is absent from the other species. The presence of the acrosome is related to the existence in Peripatoides of big eggs, which are absent in Peripatopsis.
本文描述了栉蚕Peripatoides leuckarti的精子，并将其与之前研究过的Peripatopsis的精子进行了比较。细胞的总体形状相同，保留了典型的袖套以及围绕轴丝的九条副小管的特征。线粒体衍生物存在差异，Peripatoides leuckarti有两个线粒体衍生物，且部分位于核后凹处。但最显著的发现是Peripatoides leuckarti的细胞核周围存在一层薄而扁平的顶体，而其他物种没有。顶体的存在与Peripatoides leuckarti中存在大卵子有关，而Peripatopsis中没有大卵子。
