AbstractGulella bruggeni spec. nov., G. bomvana spec. nov., G. tietzae spec. nov. and G. ndibo spec. nov. are described from the Transkei region of Eastern Cape Province, South Africa. All are minute, smooth-shelled species with complex apertural dentition. Due to their limited ranges and continuing decline in extent and quality of habitat, G. bruggeni spec. nov., G. bomvana spec. nov. and G. ndibo spec. nov. are likely to meet the distribution-based criteria for red-listing as Critically Endangered and G. tietzae spec. nov. as Endangered. G. aprosdoketa and G. chi are discussed and illustrated for comparison and the known distribution of each is extended.
