Summary Details about the record of a juvenile mermithid roundworm parasitizing the bark spider Caerostris sumatrana Strand, 1915 from Thailand are presented. The morphology and ecology of both organisms is discussed. Morphological features suggest this juvenile nematode belongs to the genus cf. Aranimermis. Due to the subadult stage of parasite, identification to species-level was not possible. This first report of a nematode infection in C. sumatrana with several recent findings from other studies significantly adds to the current inventory of mermithids parasitizing spiders. Moreover, our finding is among the first record of this host-parasite interaction from Southeast Asia.

关于东南亚蜘蛛（Araneae：Araneidae）中的mermithid寄生（Enoplea：Mermithidae）的第一份报告

总结 介绍了 1915 年来自泰国的幼虫蛔虫寄生于树皮蜘蛛 Caerostris sumatrana Strand 的记录。讨论了这两种生物的形态学和生态学。形态特征表明这种幼年线虫属于 cf 属。阿拉尼莫米斯。由于寄生虫处于亚成体阶段，因此无法进行物种级别的鉴定。C. sumatrana 中线虫感染的第一份报告以及其他研究的几项最近发现显着增加了目前寄生蜘蛛的 mermithids 的清单。此外，我们的发现是东南亚宿主-寄生虫相互作用的首批记录之一。
