在 Dikerogammarus villosus 和 Gammarus p. 中。 pulex，发现了丛神经的锁定机制。第一和第五雌性腹膜虫以及第一对雄性颌足类动物上的大孔都参与其中。在腹膜石 1 的前缘和腹膜石 5 的后缘上，发现了允许雄性指节刺入雌性节段间空间的特殊区域。此外，还发现了利用第一对颚足类动物的掌棘来引导雄性附着于雌性的引导系统。对该机制进行了描述和讨论。这种锁定系统的形态测量分析解释了伙伴之间强烈的尺寸关系。
In Dikerogammarus villosus and Gammarus p. pulex, a lock-on mechanism for amplexus was found. Large pores on the first and fifth female pereionites are involved, as well as the first pair of male gnathopods. On the anterior edge of pereionite 1 and the posterior edge of pereionite 5, specialized areas were found that allow penetration of the male's dactyli in the inter-segmental spaces of the female. Also, a guidance system for male attachment to the female was found using palmar spines of the first pair of gnathopods. The mechanism is described and discussed. Morphometric analysis of this lock-on system explains the strong size-relationship between partners.
