传统上，通过形态特征来识别物种，使得类群中未描述的神秘物种处于形态保护选择（或缺乏形态变化选择）之下。爬行树（属：Certhia）具有保守的形态外观，因此很难仅根据形态来确定该属的关系。最近对欧亚爬树鸟的遗传和歌曲结构研究发现了旧世界 Certhia 中的神秘物种，这些物种以前从未使用形态特征进行过描述。在这里，我们使用 mtDNA 来研究棕色爬行者（Certhia americana）的神秘多样性和多样化模式，这是美洲唯一描述的 Certhia 物种。系统发育分析确定了六个得到充分支持的地理结构进化枝；基本分歧将棕色爬行者的北部和南部谱系分开，这可能是以前被描述为许多亚种的神秘物种。北美西部的分支之间普遍存在同情心，其中可能的接触区值得进一步调查。异域分布似乎是棕爬行者深层系统发育地理结构的主要驱动力。然而，进化枝内部的多样性与构成地理结构系统群的种群的生活史特征高度相关。
The identification of species via morphological characteristics has traditionally left cryptic species undescribed in taxa under selection for morphological conservation (or a lack of selection for morphological change). Treecreepers (Genus: Certhia) have a conserved morphological appearance, making it difficult to ascertain relationships in the genus based on morphology alone. Recent genetic and song structure studies of Eurasian Treecreepers identified cryptic species within Old World Certhia that were previously undescribed using morphological characteristics. Here, we use mtDNA to investigate cryptic diversity and patterns of diversification in the Brown Creeper (Certhia americana), the single described Certhia species in the Americas. Phylogenetic analyses identified six well-supported geographically-structured clades; the basal divergence separates a northern and a southern lineage in the Brown Creeper, likely cryptic species previously characterized as many subspecies. Sympatry is prevalent between clades in western North America, where possible contact zones warrant further investigation. Allopatry appears to be the primary driver of deep phylogeographic structure within the Brown Creeper; however, within clade diversity is highly correlated with the life history traits of the populations that comprise the geographically structured phylogroups.
