在形态相似的物种中发现遗传和行为多样性导致了隐物种复合体的发现。我们通过检查由mtDNA定义的三个不同分支的配偶吸引信号，验证了美国峡谷树蛙（Hyla arenicolor）种群可能由隐藏物种组成的假设。使用多位点方法，我们重新分析了这三个分支和一个密切相关但形态和行为不同的物种——亚利桑那树蛙（H. wrightorum）之间的系统发育关系。我们发现了H. wrightorum线粒体基因组渗入到H. arenicolor的证据。此外，基于核数据的两枝拓扑结构比来自线粒体数据集的三枝拓扑结构更符合呼叫变化模式。叫声差异的程度可能不足以促进核dna定义的进化支的分离，如果它们成为同域的，但在物种鉴定中具有重要意义的叫声特性的进一步差异可能会促进未来的物种形成。
Detection of genetic and behavioral diversity within morphologically similar species has led to the discovery of cryptic species complexes. We tested the hypothesis that U. S. populations of the canyon treefrog (Hyla arenicolor) may consist of cryptic species by examining mate-attraction signals among three divergent clades defined by mtDNA. Using a multi-locus approach, we re-analyzed phylogenetic relationships among the three clades and a closely related, but morphologically and behaviorally dissimilar species, the Arizona treefrog (H. wrightorum). We found evidence for introgression of H. wrightorum’s mitochondrial genome into H. arenicolor. Additionally, the two-clade topology based on nuclear data is more congruent with patterns of call variation than the three-clade topology from the mitochondrial dataset. The magnitude of the call divergence is probably insufficient to promote isolation of the nuclear-DNA defined clades should they become sympatric, but further divergence in call properties significant in species identification could promote speciation in the future.
