A new species of capsalid monogenean, Benedenia armata n. sp., is described from Lethrinus haematopterus Temminck & Schlegel (Perciformes: Lethrinidae) from off Danjo Islands, Nagasaki Prefecture, Japan. The new species differs from other species of Benedenia Diesing, 1858 in that the common genital atrium has spines and the vas deferens has two swellings. Lethrinus haematopterus has been considered as the type-host of Benedenia ishikawae (Goto, 1894) based on the local name 'Kuchibi-dai'. However, this name refers not only to L. haematopterus but also to L. nebulosus (Forsskål), and L. haematopterus examined in this study was not infected by B. ishikawae. Further study is required to determine the type-host of B. ishikawae and to redetermine the species of Benedenia that are parasitic on Lethrinus spp. in the type-locality of B. ishikawae (Hagi, Yamaguchi Prefecture, Japan).
一种新的锚首虫科单殖吸虫，武装贝内登虫（Benedenia armata n. sp.），是从日本长崎县丹岛附近的红鳍裸颊鲷（Lethrinus haematopterus Temminck & Schlegel，鲈形目：裸颊鲷科）中描述的。该新物种与1858年的贝内登虫属（Benedenia Diesing）的其他物种不同之处在于，共同生殖腔有刺且输精管有两个膨大部。基于当地名称“Kuchibi-dai”，红鳍裸颊鲷一直被认为是石川贝内登虫（Benedenia ishikawae，Goto，1894）的模式宿主。然而，这个名称不仅指红鳍裸颊鲷，还指星云裸颊鲷（L. nebulosus，Forsskål），并且本研究中检查的红鳍裸颊鲷未被石川贝内登虫感染。需要进一步研究以确定石川贝内登虫的模式宿主，并重新确定在石川贝内登虫模式产地（日本山口县萩）寄生于裸颊鲷属鱼类上的贝内登虫物种。
