摘要

A total of 52 specimens of the Pacific seabream Acanthopagrus pacificus Iwatsuki, Kume et Yoshino from the Gulf of Tonkin off Vietnam were examined for monogeneans. Twenty fish were parasitised by 101 individuals of five monogenean species, including two known species Allodiscocotyla diacanthi Unnithan, 1962 and Heterapta chorinemi (Tripathi, 1956), as well as three new species, Polylabroides tienyenensis sp. n., Polylabroides tonkinensis sp. n. and Metacamopia lebedevi sp. n. Polylabroides tienyenensis and P. tonkinensis are morphologically more similar to Polylabroides guangdongensis Zhang et Yang, 2001 in comparison with other species within the genus, based on the absence of small spines on the cirrus. However, P. tonkinensis is distinguished from P. guangdongensis by fewer clamps on the haptor and by the different shapes of the large spines on the cirrus. Similarly, P. tienyenensis differs from P. guangdongensis by vaginal ducts with fewer branches, fewer clamps and smaller egg size. Metacamopia lebedevi is distinguished from Metacamopia chorinemi (Yamaguti, 1953) by the arrangement of testes (one row vs two rows), diverticula absent in the oesophagus, and the number of anchor pairs (one vs two); it differs from Metacamopia oligoplites Takemoto, Amato et Luque, 1996 by the smaller haptor, shape and absence of small sclerotised hooks, the number of ribs in their clamps, and the position of the testes; it can be separated from Metacamopia indica (Unnithan, 1962) by having fewer testes and lacking sclerotised structures in the vagina. The present study also provides the measurements for A. diacanthi, H. chorinemi, and proposes a new key to all species of Polylabroides.

Tonkinensis与Polydongersis Zhangongsis Zhangensis Zhangensis Zhang Et Yang的形态学相比，与属属中的其他物种相比，基于卷曲的小脊椎。然而，P. Tonkinensis通过唤醒的夹具较少的夹具和Cirrus上的大刺的不同形状不同于广东省的P.Conangensis。同样，P. Tienyenensis通过阴道导管与较少分支，夹具较少和较小的鸡蛋尺寸的阴道导管不同。 Metacamopia Lebedevi通过睾丸（一排与两排），缺席食道缺席的雌克莫昔帕米胺（Yamaguti，1953）的区别于，并且锚对（一个VS两）;它与Metacamopia Oligoplites Takemoto，Amato et Luque，1996年由较小的静脉，形状和没有小型硬化钩，其夹子中的肋骨数量，以及睾丸的位置;它可以通过较少的睾丸和阴道中缺乏渗透结构来分离成metacamopia indica（Unitnithan，1962）。本研究还为A. diacanthi，H. chorinemi提供了测量，并提出了所有物种的新键聚物的新关键。
