天蛾属天蛾科天蛾属天蛾属天蛾科天蛾属天然而，一个强大的系统发育框架的家庭是目前缺乏。形态学无法确定大多数群体之间的关系。作为理解这个模型组的关系的一个重要步骤，我们已经进行了第一次大规模的分子系统发育分析的天蛾代表所有亚科，部落和亚部落。数据集包括131个鞘氨醇物种和来自5个蛋白质编码核基因的6793 bp序列。最大似然法和简约法分析为三分之二以上的节点提供了强有力的支持，包括支持或反对几乎所有15个当前亚科、部落和亚部落群的强有力信号。单系是其中一些，包括Macroglossinae，Sphinginae，Acherontiini，Ambulycini，Philampelini，Choerocampina和Hemarina强烈支持。其他的类群被证明是帕拉系或多系的，需要重新定义;这些类群包括Smerinthinae、Smerinthini、Sphingini、Sphingulini、Dilophonotini、Dilophonotina、Macroglossini和Macroglossina。强烈支持的基础分歧是Macroglossinae和Smerinthinae+Sphinginae之间。所有基因对来自组合数据集的信号都有显著贡献，并且基因之间几乎没有冲突。祖先国家的重建揭示了新世界和旧世界辐射的多个独立起源。我们的研究提供了第一个最引人注目和研究最充分的昆虫之一的全面发育。分子系统发育学对目前天蛾科的形态学概念提出了挑战，并为天蛾科的新分类提供了基础。虽然有多个独立的起源新世界和旧世界的辐射，我们得出结论，大规模的地理分布在天蛾是更多的遗传保守比以前假设的。
The 1400 species of hawkmoths (Lepidoptera: Sphingidae) comprise one of most conspicuous and well-studied groups of insects, and provide model systems for diverse biological disciplines. However, a robust phylogenetic framework for the family is currently lacking. Morphology is unable to confidently determine relationships among most groups. As a major step toward understanding relationships of this model group, we have undertaken the first large-scale molecular phylogenetic analysis of hawkmoths representing all subfamilies, tribes and subtribes. The data set consisted of 131 sphingid species and 6793 bp of sequence from five protein-coding nuclear genes. Maximum likelihood and parsimony analyses provided strong support for more than two-thirds of all nodes, including strong signal for or against nearly all of the fifteen current subfamily, tribal and sub-tribal groupings. Monophyly was strongly supported for some of these, including Macroglossinae, Sphinginae, Acherontiini, Ambulycini, Philampelini, Choerocampina, and Hemarina. Other groupings proved para- or polyphyletic, and will need significant redefinition; these include Smerinthinae, Smerinthini, Sphingini, Sphingulini, Dilophonotini, Dilophonotina, Macroglossini, and Macroglossina. The basal divergence, strongly supported, is between Macroglossinae and Smerinthinae+Sphinginae. All genes contribute significantly to the signal from the combined data set, and there is little conflict between genes. Ancestral state reconstruction reveals multiple separate origins of New World and Old World radiations. Our study provides the first comprehensive phylogeny of one of the most conspicuous and well-studied insects. The molecular phylogeny challenges current concepts of Sphingidae based on morphology, and provides a foundation for a new classification. While there are multiple independent origins of New World and Old World radiations, we conclude that broad-scale geographic distribution in hawkmoths is more phylogenetically conserved than previously postulated.
