Communication during tandem running inPachycondyla obscuricornis is chemically mediated by a pheromone produced in the pygidial gland, which is composed of a cluster of gland cells and an associated reservoir located beween the 6th and 7th tergites of the gaster. The secretion of the gland appears to be transferred to the hindlegs of a tandem pair leader by a series of self-grooming behaviors that occur prior to the formation of a tandem pair. During tandem running, the antennae of the following ant are kept in close contact with the leader's hindlegs and therefore with the chemical signal that provides a communicative bond between individuals.
在窄胸穿山甲中，同步运行时的通讯是通过位于腹部第 6 到第 7 节之间的 pygidial 腺所分泌的一种信息素来介导的，这种信息素由一群腺细胞和一个相关的储液器组成。腺体的分泌似乎是通过一系列在形成同步对之前发生的自我梳理行为转移到同步对的前导蚁的后肢上的。在同步运行时，后续蚂蚁的触角与前导蚁的后肢保持紧密接触，因此也与提供个体间通讯联系的化学信号保持紧密接触。
