Philampelina Burmeister, 1878

Since Rothschild & Jordan (1903), Philampelini has been treated as a tribe of Macroglossinae comprising only the genera Eumorpha and Tinostoma. However, the results of the analysis of the higher classification of Sphingidae using five nuclear genes by Kawahara et al. (2009: Figure 3) demonstrated that genus Eumorpha was part of a larger essentially New World clade that also included genera Aleuron, Amphion, Cautethia, Enyo, Euproserpinus, Pachygonidia, Proserpinus, Sphecodina and Unzela. The subclade comprising these genera except Cautethia had only moderate bootstrap support (72%), and there was no support for the inclusion of Cautethia. However, the clade as a whole is tentatively treated here as an expanded subtribe Philampelina within tribe Dilophonotini. This has the effect of bringing together the majority of the New World Macroglossinae (excluding only Darapsa, Deidamia, Phanoxyla, Xylophanes and some members of Hemaris, Hyles and Neogurelca) into a single clade. However, this must be considered a highly provisional arrangement that is likely to change in the light of new data. To this subtribe can be added genus Himantoides (as the possible sister-group of Cautethia), and genus Tinostoma (q.v.) is moved to a position incertae sedis in Macroglossina. Under the First reviser principle, Philampelina is here treated as the senior synonym of Pterogonidae.
