(Erythroxylaceae); A. barrinhensis sp. nov. on Diospyros burchellii (Ebenaceae); A. campograndensis sp. nov. on Hirtella glandulosa (Chrysobalanaceae); A. parinaricola sp. nov. on Parinari obtusifolia (Chrysobalanaceae); and Cirsosia splendida var. laevigata var. nov., showing both sexual and asexual morphs, on H. glandulosa and H. gracilipes (Chrysobalanaceae). Finally, A. licaniae is reported on a new host, H. gracilipes. Keys to all the known species of Asterolibertia and Cirsosia are included.
