Based on light and scanning electron microscopical studies of nematode specimens from the digestive tract of some rarely collected anguilliform and perciform fishes off New Caledonia, three new species of Cucullanus Müller, 1777 (Cucullanidae) are described: C. austropacificus n. sp. from the longfin African conger Conger cinereus (Congridae), C. gymnothoracis n. sp. from the lipspot moray Gymnothorax chilospilus (Muraenidae), and C. incognitus n. sp. from the seabream Dentex fourmanoiri (Sparidae). Cucullanus austropacificus n. sp. is characterized by the presence of cervical alae, ventral sucker, alate spicules 1.30-1.65 mm long, conspicuous outgrowths of the anterior and posterior cloacal lips and by elongate-oval eggs measuring 89-108 × 48-57 μm; C. gymnothoracis n. sp. is similar to the foregoing species, but differs from it in the absence of cervical alae and the posterior cloacal outgrowth, in the shape and size of the anterior cloacal outgrowth and somewhat shorter spicules 1.12 mm long; C. incognitus n. sp. (based on female morphology) differs from other congeneric species parasitic in the Sparidae mainly in possessing cervical alae, the postequatorial vulva, phasmids situated at the mid-length of the tail and in the size of the eggs (75-84 × 45-66 μm). A key to species of Cucullanus parasitizing anguilliform fishes is provided.
基于对新喀里多尼亚附近一些罕见的鳗形目和鲈形目鱼类消化道中线虫标本的光学显微镜和扫描电子显微镜研究，描述了3种新的1777年穆勒氏库氏线虫属（库氏线虫科）物种：来自长鳍非洲康吉鳗康吉鳗（康吉鳗科）的南太平洋库氏线虫新种、来自唇斑裸胸鳝裸胸鳝（海鳝科）的裸胸鳝库氏线虫新种和来自四线笛鲷笛鲷（笛鲷科）的隐匿库氏线虫新种。南太平洋库氏线虫新种的特征为具有颈翼、腹吸盘、长1.30 - 1.65毫米的翼状交合刺、明显的泄殖孔前后唇突出以及长椭圆形的卵，大小为89 - 108×48 - 57微米；裸胸鳝库氏线虫新种与上述物种相似，但没有颈翼和泄殖孔后突出，泄殖孔前突出的形状和大小不同，交合刺稍短，长1.12毫米；隐匿库氏线虫新种（基于雌性形态）与寄生在笛鲷科鱼类上的其他同属物种的主要区别在于具有颈翼、赤道后阴门、位于尾中部的尾感器以及卵的大小（75 - 84×45 - 66微米）。提供了寄生在鳗形目鱼类上的库氏线虫属物种检索表。
