The following new recent species of mermithid (Nematoda) parasites of Neotropical ants are described: Meximermis ectatommi n.gen., n. sp. from workers of Ectatomma ruidum Roger in Southern Mexico, Agamomermis cephaloti n. sp. from a worker of Cephalotes minutus (Fab.) collected in Brazil, Agamomermis ecitoni n. sp. from a worker of Eciton burchellii Westwood collected in Venezuela and Agamomermis costaricensis n. sp. from a worker of Odontomachus hastatus (Fab.) collected in Costa Rica. In addition, a fossil mermithid parasite of a worker of Linepithema sp. from Dominican amber is described as Heydenius myrmecophila n. sp. These parasites represent the first descriptions of Neotropical ant mermithids and together with previous records listed here, show that ant infection by mermithids in the Neotropics is widespread and has occurred for at least 20-30 million years.
以下是对新热带区蚂蚁的新种索线虫（线虫纲）寄生虫的描述：来自墨西哥南部的鲁氏弓背蚁工蚁的新属新种墨西哥弓背蚁索线虫；来自在巴西采集的微小举腹蚁工蚁的新种头举腹蚁索线虫；来自在委内瑞拉采集的布氏游蚁工蚁的新种游蚁索线虫；来自在哥斯达黎加采集的戟齿蚁工蚁的新种哥斯达黎加索线虫。此外，来自多米尼加琥珀中一种皱胸蚁属工蚁的化石索线虫寄生虫被描述为新种蚁嗜海登线虫。这些寄生虫代表了新热带区蚂蚁索线虫的首次描述，并且与这里列出的先前记录一起表明，新热带区蚂蚁被索线虫感染的情况很普遍，且至少已经发生了2000万至3000万年。
