The taxonomic concepts of endemic South African genera Parastizopus Gebien, 1938 and Ennychiatus Koch, 1963 are verified. The results of the study are based on the comparative morphological analysis and gave the following decisions: (1) new concept of the Parastizopus is based on the discontinuous and unambiguous diagnostic characters, (2) all species of the Ennychiatus belong to the genus Parastizopus; (3) the name Ennychiatus should be treated as a junior synonym of Parastizopus; (4) the following new combination are proposed: Parastizopus nocturnus (Koch, 1963), P. caraboides (Fairmaire, 1897), P. namaquanus (Koch, 1963), P. fitzsimonsi (Koch, 1963). The division of the Parastizopus into the following species groups is proposed: armaticeps (3 species), caraboides (4) and major (3). New species P. johannae sp. nov. from Southern Africa is diagnosed, described and illustrated. A checklist and the identification key is provided to all known species of Parastizopus.
