Abstract

The South African endemic humicolous genus Nucleotops Perkins and Balfour-Browne is revised. Nucleotops comprises three species from the Cape Province. Two new species are described: N. endroedyi (Cape Province, 5 km NE Pearly Beach) and N. interceps (Cape Province, Stellenbosch, Krom River). The vast majority of the 1,462 specimens studied were collected by sifting humus, marsh shore debris or moist litter. High resolution digital images of the holotypes are presented (online version in color), the male genitalia are illustrated, and the geographical distributions are mapped.
