DNA 条形码用于验证特征，以在形态上区分北美东部小木蜂 Ceratina 的遗传不同物种。在这里，我们揭示了北美东部常见的物种 Ceratina dupla s。 l.，实际上是基于 DNA 条形码序列和形态特征的固定差异的三个独立物种。这项研究在北美洲东部的 Ceratina dupla 物种组中添加了一个新物种 C. mikmaqi Rehan & Sheffield，并将另一种形式 C. floridana（以前称为 C. dupla floridana）提升为完整物种。 C. dupla 和 C. mikmaqi 之间的时间生态位划分以及 C. floridana 的地理隔离进一步支持了 C. dupla 的划分。湖分为三个种类。提供了新物种的诊断和描述，这是北美东部赛拉蒂纳物种的关键。
DNA barcoding is used to verify characters to morphologically differentiate genetically distinct species of eastern North American small carpenter bees, Ceratina. Here we reveal that the common eastern North American species, Ceratina dupla s. l., is actually three separate species based on fixed differences in DNA barcode sequences and morphological characters. This study adds a new species, C. mikmaqi Rehan & Sheffield, to the Ceratina dupla species-group of eastern North America, and raises another form, C. floridana formerly C. dupla floridana, to full species. Temporal niche partitioning between C. dupla and C. mikmaqi and geographic isolation of C. floridana further support the division of the C. dupla s. l. group into three species. A diagnosis and description of the new species are provided, as is a key for eastern North American species of Ceratina.
