The number of sibling species of anisakid nematodes detected over the last two decades has been increased, fuelled by the use of genetic/molecular methodologies. In the present review, we summarize the biological species discovered within most of the nominal species belonging to the genera Anisakis, Contracaecum and Pseudoterranova by the use of allozyme (20-24 loci studied) and recently confirmed by us using mitochondrial cox-2 gene sequence analysis (mtDNA cox-2). Ecological evidence relating to the distributional range of the genetically detected sibling species and their host preferences, which represent data sets that can be utilized for species delimitation and definition, are summarized.
在过去二十年中，由于遗传/分子方法的应用，异尖线虫属线虫的姐妹物种数量有所增加。在本综述中，我们总结了通过等位酶分析（研究了20 - 24个位点）在异尖线虫属、对盲囊线虫属和拟新地蛔线虫属的大多数名义物种中发现的生物学物种，并且我们最近通过线粒体细胞色素氧化酶亚基2基因序列分析（mtDNA cox-2）对此进行了确认。总结了与通过遗传学检测到的姐妹物种的分布范围及其宿主偏好相关的生态学证据，这些证据可作为用于物种界定和定义的数据集。
