Ambuycini是飞蛾科的一个世界性部落，由10个属组成，其中3个属在热带亚洲，4个在新热带地区，1个在非洲，1个在中东，1个仅限于新喀里多尼亚群岛。最近对该部落的系统发育分析得出了相互矛盾的结果，一些人提出，尽管发现于太平洋的对岸，但单基的新喀里多尼亚属Compsulyx Holloway，1979与新热带属关系密切。在这里，我们使用完整的线粒体基因组来研究部落内部的关系，这些基因组主要来自于干针固定的博物馆收藏品。获得了19个种的有丝分裂数据，分别代表10个Ambuycini属中的9个。该部落的系统发育树与热带亚洲人的起源一致。此外，结果还表明，新热带属Adhemarius Oiticica Filho，1939是近源的，并支持Orecta Rothschild&Jordan 1903和TroGolegnum Rothschild&Jordan，1903可能是同名的观点。最后，在我们的分析中，由于一个由新喀里多尼亚属Compsulyx和非洲属Batocnema Rothschild&Jordan，1903年被归类为新热带属ProTambuyx Rothschild&Jordan，1903的分支，新热带属并不共同形成一个单系群。这一发现暗示了一段复杂的生物地理史，并表明该部落的进化至少涉及两次远程扩散事件。
Ambulycini are a cosmopolitan tribe of the moth family Sphingidae, comprised of 10 genera, 3 of which are found in tropical Asia, 4 in the Neotropics, 1 in Africa, 1 in the Middle East, and 1 restricted to the islands of New Caledonia. Recent phylogenetic analyses of the tribe have yielded conflicting results, and some have suggested a close relationship of the monobasic New Caledonian genus Compsulyx Holloway, 1979 to the Neotropical ones, despite being found on opposite sides of the Pacific Ocean. Here, we investigate relationships within the tribe using full mitochondrial genomes, mainly derived from dry-pinned museum collections material. Mitogenomic data were obtained for 19 species representing nine of the 10 Ambulycini genera. Phylogenetic trees are in agreement with a tropical Asian origin for the tribe. Furthermore, results indicate that the Neotropical genus Adhemarius Oiticica Filho, 1939 is paraphyletic and support the notion that Orecta Rothschild & Jordan 1903 and Trogolegnum Rothschild & Jordan, 1903 may need to be synonymized. Finally, in our analysis the Neotropical genera do not collectively form a monophyletic group, due to a clade comprising the New Caledonian genus Compsulyx and the African genus Batocnema Rothschild & Jordan, 1903 being placed as sister to the Neotropical genus Protambulyx Rothschild & Jordan, 1903. This finding implies a complex biogeographic history and suggests the evolution of the tribe involved at least two long-distance dispersal events.
