Acanthoplus discoidalis is a species in the Hetrodinae, a subfamily of the katydid family (Tettigoniidae). Like its closest relatives, Acanthoplus discoidalis variously bears common names such as armoured katydid, armoured ground cricket, armoured bush cricket, corn cricket, setotojane and koringkriek. The species is native to parts of Angola, Namibia, Botswana, Zimbabwe and South Africa.

Note that the common names are characteristically misleading; the species is not closely related to true crickets and "katydids" which originally belonged to the unrelated subfamily Pseudophyllinae.
