Shen-Horn Yen, Ian J. Kitching and Chao-Shian Tzen (2003)Macroglossum lanyuana Chen” was first recorded from Lanyu (Orchid Island), Taiwan, in 1994, but this manuscript name has not been made available under the International Code of Zoological Nomenclature. We herein describe this taxon as Macroglossum ungues cheni ssp. nov. The relationships and biogeography of M. ungues Rothschild and Jordan, 1903 are discussed. The occurrence of M. ungues cheni on Lanyu corroborates geological evidence for the origin of the island. We also present an annotated checklist of the Taiwanese Sphingidae as an update to the Lepidoptera of Taiwan published in 1992.

Key words: Biogeography, Neo-Wallace’s Line, Peripheral population.
