隐种不断发现轮虫使用不同的方法来划定这些单位的多样性。DNA分类学是分类学家解开潜在的隐藏分类单元的最有效的方法。在这里，我们估计隐藏的多样性蛭形轮虫，Adineta属。我们分析了隐藏的多样性，使用合并的方法来推断从细胞色素氧化酶I序列获得的系统发育树的进化显着的单位。隐藏的多样性进行了测量，为8个传统的物种，并从几个额外的未确定的人口。在A. DNA taxonomy分类正如在其他微生物中观察到的那样，每个传统物种中的隐藏类群在地理上并不孤立，但其生态位比预期的要窄得多。
Cryptic species are continuously discovered in rotifers using different methods to delineate these units of diversity. DNA taxonomy is the most effective method taxonomists have to untie potential cryptic taxa. Here, we estimate hidden diversity in a genus of bdelloid rotifers, Adineta. We analyse cryptic diversity using a coalescent approach to infer evolutionarily significant units from a phylogenetic tree obtained from cytochrome oxidase I sequences. Cryptic diversity was measured for eight traditional species and from several additional undetermined populations. Taxonomic inflation of up to 36 taxa was found in A. vaga from DNA taxonomy. As observed in other microscopic organisms, cryptic taxa within each traditional species were not geographically isolated, but had significantly narrower ecological niches than expected by chance alone.
