Recent occasional examinations of two species of eels (Anguilliformes: Anguillidae) in Japan, the Japanese eel Anguilla japonica Temminck & Schlegel from central Japan and the giant mottled eel Anguilla marmorata Quoy & Gaimard from southern Japan, respectively, revealed the following four species of gastrointestinal parasitic nematodes: Cucullanus filiformis Yamaguti, 1935 (Cucullanidae) from A. japonica; Paraquimperia japonica n. sp. (Quimperiidae) from A. japonica (type-host) and A. marmorata; Heliconema anguillae Yamaguti, 1935 (Physalopteridae) from A. marmorata (new host record); and Spinitectus anguillae n. sp. (Cystidicolidae) from A. japonica (type-host) and A. marmorata. Specimens of all species are described based on light and scanning electron microscopical examinations. Paraquimperia japonica n. sp. is mainly characterised by the presence of a ventral sucker, spicules 210-231 µm long and by narrow cervical alae, whereas S. anguillae n. sp. by the number (29-36) of cuticular spines in the first ring, the length of the left spicule (351 µm) and the structure (without polar caps, filaments or lateral swellings), and the size of eggs (36-42 × 21-27 µm).
最近对日本两种鳗鲡（鳗鲡目：鳗鲡科）的偶尔检查，分别是来自日本中部的日本鳗鲡 Anguilla japonica Temminck & Schlegel 和来自日本南部的大斑鳗鲡 Anguilla marmorata Quoy & Gaimard，发现了以下四种胃肠道寄生线虫：Cucullanus filiformis Yamaguti, 1935（Cucullanidae）来自 A. japonica；Paraquimperia japonica n. sp.（Quimperiidae）来自 A. japonica（模式宿主）和 A. marmorata；Heliconema anguillae Yamaguti, 1935（Physalopteridae）来自 A. marmorata（新宿主记录）；和 Spinitectus anguillae n. sp.（Cystidicolidae）来自 A. japonica（模式宿主）和 A. marmorata。所有物种的标本均基于光镜和扫描电子显微镜检查进行描述。Paraquimperia japonica n. sp. 的主要特征是具有腹吸盘、210-231 µm 长的棘和狭窄的颈翼，而 S. anguillae n. sp. 的特征是第一环有 29-36 个表皮刺、左棘的长度（351 µm）和结构（无极帽、丝状体或侧膨胀）以及卵的大小（36-42×21-27 µm）。
