Systematics and biogeography of the genus Gadaca Moore (Lepidoptera: Pieridae) Systematics and Biogeography of the Genus Gandaca Moore (Lepidoptera : Pieridae)

All known species of the genus Gandaca; G. harina (Horsfield) and G. butyrosa (Butler) are redescribed and illustrated, with female genitalia illustrated for the first time. They are distinguished by wing markings, and male and female genitalia, and a key to species is provided. The subspecies G. harina auriflua (Fruhstorfer) stat. rev. from Sula and Banggai is Indonesia is transferred from G. butyrosa. A distribution map of both species is presented. From the viewpoint of biogeography, the remarkable distribution pattern of both species is discussed.
