A striking new sandveld lizard of the Nucras tessellata group is described from the Lambert’s Bay Strandveld of the Western Cape Province, South Africa. It is sister to the clade N. livida + N. tessellata, and is phenetically most similar to N. tessellata, from which it differs in its more elongate body and possibly increased number of presacral vertebrae and patternless orange dorsal coloration. The form elegans, described as a species by Andrew Smith (1838), but treated as an infrasubspecific variant by Broadley (1972), also exhibits weak patterning, but is likely a regional color variant. Nucras aurantiaca sp. nov. is the ninth member of the genus found in southern Africa. Its discovery in the well-collected coastal Western Cape suggests that further herpetofaunal surveys are needed in this region, which is threatened by agricultural activity and tourism-related development.

Data relating to the Sandveld lizards (Nucras) occurring in Namibia, southwest Africa are reviewed. In particular, we investigated records of N. holubi, a chiefly southeastern African species, and attempted to identify recently collected material that could not be assigned to any species currently recognized in Namibia. A phylogenetic analysis of Nucras based on three mitochondrial markers revealed a deep divergence between Namibian Nucras holubi and two presumably conspecific clades from Limpopo Province, South Africa. In addition, the coloration pattern and scalation of the Namibian material differ from those of the eastern forms, supporting its recognition as a separate species. The name Nucras damarana Parker, 1936, long relegated to the synonymy of N. holubi, is here resurrected for this apparently endemic northern Namibian species. Nucras damarana is restricted to the Kunene, Omusati, Oshikati, Kavango, and Otjozondjupa regions of north-central Namibia. A distinctive specimen of Nucras from near Ruacana in the Kunene Region was identified as allied to Nucras broadleyi, a species recently described from southwestern Angola, on the basis of genetic data, although it differs substantially in color pattern. With the addition of N. aff. broadleyi and the resurrected N. damarana to its fauna, as well as the removal of N. holubi from the nation’s species list, four species of Nucras are confirmed to be present in Namibia. Although the conservation status of N. damarana, N. tessellata, and N. intertexta is Least Concern, the uncertain taxonomic status of N. aff. broadleyi precludes a meaningful threat assessment.
