摘要描述了两科四种钝尾鱼的生殖生物学和精荚形态。基本上，对Sarax buxtoni、S. brachydactylus，Stygophrynus brevispina nov. spec.和Charon cf.灰蜘蛛和许多其他鞭蛛相似然而，每个物种都有自己的特点。与其他物种一样，雌性在求偶过程中并不被动;她用自己的求偶信号扮演着积极的角色，甚至可能发起求偶行为。本文对苏云金杆菌精囊进行了比较研究。buxtoni和S. sarawakensis与S.短趾龙有两种不同类型的精囊。目前，这三个物种应该被包括在同一个分类单元中，只要没有已知的共形，Phrynichosarax应该被认为是Sarax的初级同义词。交配行为和精荚形态。参见来自两个不同地区的灰衣表明它们代表不同的物种。它们的行为和精囊以及Stygophrynus brevispina的行为和精囊支持Stygophrynus和Charon在Charontidae分类单元中的位置。Charon精荚头上的侧角的存在提出了一个问题，即这些结构是否是Neoamblypygi甚至Euamblypygi的突触。这个问题目前还不能得到结论性的回答。
Abstract Reproductive biology and spermatophore morphology of four species of Amblypygi, belonging to two different families, are described. Basically, courtship and mating in Sarax buxtoni, S. brachydactylus, Stygophrynus brevispina nov. spec. and Charon cf. grayi are similar to those of many other whip spiders. However, each species has its own peculiarity. Like in other species, the female is not passive during courtship; she plays an active role with her own courtship signals and may even initiate courtship behaviour. The comparison of the spermatophores of S. buxtoni and S. sarawakensis with S. brachydactylus show two different types of spermatophores. At present, all three species should be included in the same taxon and Phrynichosarax should be considered a junior synonym of Sarax as long as there are no synapomorphies known. Mating behaviour and spermatophore morphology of C. cf. grayi from two different localities suggest both represent different species. Their behaviour and spermatophores and that of Stygophrynus brevispina supports the placement of the genera Stygophrynus and Charon in the taxon Charontidae. The presence of lateral horns on the spermatophore head of Charon raises the question of whether these structures are synapomorphic for the Neoamblypygi or even Euamblypygi. This question cannot be answered conclusively at present.
