Mariepskopia albomaculata gen. et sp. nov. from South Africa is described. The genus is placed into the tenebrionid tribe Cnodalonini and has no closer relative in Africa, but probably in the Oriental Region with the genus Asbolodes. The species has a small distribution area in Mpumalanga and KwaZulu-Natal and has probably an arboreal mode of life in the montane forest in 1300–1600 m altitude.
