Species from the Southern Hemisphere differ by the absence of ms-chaetae on Abd.II and anterior position of s4-chaetae (if present) on Abd.IV ( Potapov et al . 2011 ). Taxonomy of the genus Parisotoma was developed by Fjellberg (1977) , Deharveng (1981) , Rusek (1984) , and Potapov (1991) . It is the most diverse genus of Isotomidae for South Africa with several species under description. Here we provide the descriptions of two new species with a reduced set of s-chaetae on the body.
