DNA条形码在分类解缠方面表现出很高的效率。然而，条形码集群不一定反映独立的生物物种。本文以中国南部海域的文蛤为例，说明条形码研究中发现的隐蔽物种的物种地位是如何被补充的证据所证实的。在基于距离和基于系统发育的方法下，使用6个基因片段迭代地划定了Proapes内的物种边界。结果表明，非鱼复合体中的候选种是独立的生物学种，而在非鱼复合体中还存在两个隐藏种。辛诺萨。我们的结果是西太平洋轮廓类物种数量的两倍，这表明它在该地区的生物多样性可能被严重低估。
DNA barcoding has shown high efficiency in taxonomy disentanglement. However, barcode clusters do not necessarily reflect independent biological species. Herein, Protapes clams in seas of the south China were used as a case study to illustrate how additional lines of evidences confirm the species status of cryptic species uncovered in barcoding studies. Species boundaries within Protapes were delimited iteratively using six gene fragments under both distance-based and phylogeny-based approaches. Our results showed that species candidates within Paphia (Protapes) gallus complex are independent biological species, and two hidden species also exist within P. (P.) sinuosa. Our results double the number of species of Protapes in the western Pacific, suggesting its biodiversity in this region might be severely underestimated.
