从饲养在水族箱中的波纹唇鱼（Arothron mappa（Lesson））和波纹裸胸鳝（Arothron nigropunctatus（Bloch et Schneider））体腔中采集到的透明新棘虫（Philometra pellucida（Jägerskiöld，1893））（线虫：新棘虫科）的新记录，并对 1992 年莫拉维克等人命名的 Philometra robusta 进行了同义化处理。
New records of Philometra pellucida (Jägerskiöld, 1893) (Nematoda: Philometridae) from the body cavity of Arothron mappa (Lesson) and Arothron nigropunctatus (Bloch et Schneider) reared in aquariums, with synonymisation of Philometra robusta Moravec, Möller et Heeger, 1992.

We encountered two cases of infection with large female nematodes of the genus Philometra Costa, 1845 in the body cavity of a map puffer Arothron mappa (Lesson) caught off Okinawa, Japan, and a blackspotted puffer Arothron nigropunctatus (Bloch et Schneider) caught off Queensland, Australia, both reared in aquariums in Japan. No morphological difference was observed between the nematodes from A. mappa and A. nigropunctatus. We identified the nematodes as Philometra pellucida (Jägerskiöld, 1893) based on their morphology. The sequences of the nematodes from both hosts were identical to each other (1,643 bp) and formed a clade with other 17 nematodes belonging to the genera Philometra and Philometroides Yamaguti, 1935 with high bootstrap value (bp = 100). It is the first time that the genetic data on P. pellucida are provided. Philometra robusta Moravec, Möller et Heeger, 1992 is synonymised with the former species.
我们在日本冲绳捕获的一条翻车鱼（Arothron mappa）和在澳大利亚昆士兰捕获的一条黑斑河鲀（Arothron nigropunctatus）的体腔中发现了两种大型雌性 Philometra 属线虫的感染病例，这两种线虫均在日本的水族箱中饲养。从 A. mappa 和 A. nigropunctatus 中分离出的线虫在形态上没有差异。我们根据其形态将线虫鉴定为 Philometra pellucida（Jägerskiöld，1893）。两个宿主的线虫序列完全相同（1643 bp），并与其他 17 种属于 Philometra 和 Philometroides Yamaguti，1935 属的线虫形成一个支系，支持率高（bp = 100）。这是首次提供 P. pellucida 的遗传数据。Philometra robusta Moravec，Möller et Heeger，1992 被归并为前一个种。
