The discovery and exploration of cryptic species have been profoundly expedited thanks to developments in molecular biology and phylogenetics. In this study, we apply a reverse taxonomy approach to the Brachionus calyciflorus species complex, a commonly studied freshwater monogonont rotifer. By combining phylogenetic, morphometric and morphological analyses, we confirm the existence of four cryptic species that have been recently suggested by a molecular study. Based on these results and according to an exhaustive review of the taxonomic literature, we name each of these four species and provide their taxonomic description alongside a diagnostic key.
多亏了分子生物学和系统发生学的发展,隐种的发现和探索得到了极大的推动。在这项研究中,我们应用反向分类学方法来研究常见的淡水单巢轮虫 Brachionus calyciflorus 种复合体,通过结合系统发育、形态计量和形态学分析,我们证实了最近分子研究提出的四种隐种的存在。基于这些结果,并根据对分类学文献的详尽回顾,我们为这四个物种命名,并提供了它们的分类描述和鉴别钥匙。
