虽然最近的分子系统发育分析ofLepidothrixmanakins（家庭Pipridae）有助于澄清他们的进化关系，几个谱系的位置仍然存在问题，因为低或冲突的分支支持。特别是L. coronatato属的其他成员和L内的关系。nattereri+L. vilasboasi+L.虹膜一直难以解决。我们使用RADcap收集限制性位点相关的DNA序列数据，并估计属Lepidothrix（18个目前公认的亚种中的17个）的第一个亚种水平的同源性，我们包括广泛的地理代表性和表型可变L。coronata我们发现强有力的支持系统发育的位置和单系的L。coronata，我们解决了两个分支分开的安第斯山脉，沿着以前的分歧时间估计和我们的评估形态和声音的证据，建议存在两个生物物种：天鹅绒侏儒鸟（L. velutina）和蓝顶侏儒鸟（L. coronata）位于安第斯山脉东部。L.内的种级关系。nattereri+L. vilasboasi+L. irisclade仍然很难解决的连接和合并为基础的分析，SNAPP分析表明，缺乏相互的单系性是由于这些类群之间广泛的等位基因共享。最后，我们证实了先前记录的L.科罗纳塔湖suavissimaas的F1个体，这与认为这两个物种之间的杂交是一个罕见的事件，交配后的生殖障碍，防止成功的回交一致。
Although recent molecular phylogenetic analyses ofLepidothrixmanakins (family Pipridae) have helped clarify their evolutionary relationships, the placement of several lineages remains in question because of low or conflicting branch support. In particular, the relationship ofL. coronatato other members of the genus and relationships within theL. nattereri+L. vilasboasi+L. irisclade have been difficult to resolve. We used RADcap to collect restriction site-associated DNA sequence data and estimate the first subspecies-level phylogeny of the genusLepidothrix(17 of 18 currently recognized subspecies), and we included extensive geographic representation of the widespread and phenotypically variableL. coronata. We found strong support for the phylogenetic position and monophyly ofL. coronata, and we resolved two clades separated by the Andes that, along with previous divergence time estimates and our assessment of morphological and vocal evidence, suggest the presence of two biological species: Velvety Manakin (L. velutina) west of the Andes and Blue-capped Manakin (L. coronata) east of the Andes. Species-level relationships within theL. nattereri+L. vilasboasi+L. irisclade remained poorly resolved in concatenated and coalescent-based analyses, with SNAPP analyses suggesting that the lack of reciprocal monophyly is due to extensive allele sharing among these taxa. Finally, we confirmed a previously documented hybrid betweenL. coronataandL. suavissimaas an F1 individual, consistent with the view that hybridization between these two species is a rare event and that postmating reproductive barriers prevent successful backcrossing.
