Abstract

Two new species, Parisotoma sexsetosa sp. nov. and P. obscurocellata sp. nov., are described from the Western Cape Province in South Africa. The former is characterized with 2+2 ocelli and 4 sensilla in the p-row on each side of three first abdominal segments, the latter with 5+5 or more ocelli and 3+3 chaetae on the postlabial area. Both species have only 6 posterior chaetae on dens. A comparison of South African and Asiatic Parisotoma species is given. Sensillar chaetotaxy of the third and fourth abdominal segments is critical in the separation of these geographically distinct groups.
