摘要

Ancyrocephalus sensu lato属是一个庞大的双足类单根植物物种群，没有明确的分类界限。尽管该分类群急需修订，但迄今为止只有三个代表种得到了分子鉴定。我们在俄罗斯阿穆尔河流域 Syumnyur 河捕获的 Perccottus glenii 的鳃中发现了 Ancyrocephalus curtus 的标本，这是一个以前未进行基因分型的物种。本研究的目的是利用 28S rRNA 基因的部分序列评估这种寄生虫的系统发育位置。在系统发生树中，A. curtus 是双齿鳗属 Gobioecetes 的姊妹类群。新的分子证据支持了关于鲤科（Ancyrocephalus sensu lato）非单系地位的假设。

Phylogenetic position of Ancyrocephalus (sensu lato) curtus Achmerov, 1952 (Monopisthocotylea, Dactylogyridae), a parasite of fish Perccottus glenii Dybowski, 1877(Gobiiformes: Odontobutidae).

The genus Ancyrocephalus sensu lato is a large assemblage of species of dactylogyrid monopisthocotyleans without clear taxonomic boundaries. Despite an urgent need for revision, only three representatives of this taxon have been molecularly characterised so far. We found specimens of Ancyrocephalus curtus, a previously non-genotyped species, in gills of Perccottus glenii caught in the River Syumnyur, Amur Basin, Russia. The aim of this study was to assess the phylogenetic position of this parasite using partial sequences of 28S rRNA gene. In the phylogenetic tree, A. curtus appeared as a sister taxon to the dactylogyrine genus Gobioecetes. The new molecular evidence supports the hypothesis about the non-monophyletic status of Ancyrocephalus sensu lato.

期刊介绍： Journal of Helminthology publishes original papers and review articles on all aspects of pure and applied helminthology, particularly those helminth parasites of environmental health, medical or veterinary importance. Research papers on helminths in wildlife hosts, including plant and insect parasites, are also published along with taxonomic papers contributing to the systematics of a group. The journal will be of interest to academics and researchers involved in the fields of human and veterinary parasitology, public health, microbiology, ecology and biochemistry.
