The genus Arbelodes Karsch (1896) is presented, currently comprising 22 species, from eastern Zambia, northern Malawi, eastern Zimbabwe, eastern Botswana, central and southern Namibia, Lesotho and South Africa. The species of this genus are found to be centred in southern Africa, with the highest diversities and endemism in montane zones of the Great Escarpment-Drakensberg (including Lesotho),

The species are closely linked to a warm temperate vegetation element, related to Afromontane forest and to a subtropical thicket with succulent components. The latter is associated with an ancient, dry subtropical forest and/or woodland; the former with mixed gymnosperm-angiosperm forests of the mid Cretaceous. According to these results the species of Arbelodes are treated herein as a potential relict of Gondwana or the Cretaceous. Thirteen new species are described based on photographs, illustrations of their wing venation and genitalia as well as information on the floristic composition of their habitats.
