Notes on the use of genus Hyloicus Hübner, 1819, with the description of a new species of the “H. pinastri complex” from Corsica (Lepidoptera, Sphingidae)

"The authors briefly discuss the merits of separating the genus Hyloicus Hübner, 1819, from the genus Sphinx Linnaeus, 1758, a treatment that has been debated for more than forty years. They provide a brief history of the development of the taxonomy of the members (all Palaearctic) of the “H. pinastri complex”. Then they report the unexpected finding that the representative of this complex on the island of Corsica represents a new species, described herein as Hyloicus corsica n. sp. It can be distinguished from its continental relatives, H. pinastri (Linnaeus, 1758) and H. maurorum Jordan, 1931, by its larger size, characters of the male genitalia and consistent genetic divergence of the standard DNA barcode marker (a fragment of COI gene). Only males have been observed so far, and the species is currently known as a Corsican endemic found in several localities in both southern and northern parts of the island."
