Macroglossum faro subsp. leytensis Eitschberger, 2006

Synonymized with Macroglossum faro as a subspecies by Kitching and Rougerie et al., 2018, Biodivers. Data J. 6: e22236. Given the very close similarity in both habitus and genital morphology between this taxon and both Macroglossum faro faro and Macroglossum faro cottoni, it is difficult to understand why it was described as a species and not as a subspecies of Macroglossum faro. DNA barcode sequences in BoLD (HT & PT of Macroglossum leytensis) show that Macroglossum leytensis is phenetically closer to Macroglossum faro faro than is Macroglossum faro cottoni. Consequently, for consistency with the approach adopted here with regard to other similar cases of large Macroglossum, Macroglossum leytensis is treated as a subspecies of Macroglossum faro.
