The status of the races of the graceful crag lizard, Pseudocordylus capensis, from South Africa Y.M. Herselman, P. le F.N. Mouton, J.H. Van Wyk J. Ellerman Museum, Department of Zoology, University of Stellenbosch, Stellenbosch, 7600 Republic of South Africa Abstract. To evaluate the taxonomic status of the races of the graceful crag lizard, Pseudocordylus capensis, geographical variation in 44 external morphological characters was determined, using 97 specimens from 31 localities. Two different epiphenotypes predominate in the northern and southwestern parts of the distribution range. These epiphenotypes are, however, connected by a continuum of variation. It is there- fore suggested that the recognition of races be abandoned in the formal taxonomy. Several new distribution records for the species are provided. Introduction The specific and subspecific status of the races of the graceful crag lizard, Pseudocordylus capensis, has remained unresolved until now. The nominate species was described by Smith (1838) as Cordylus (Hemicordylus) capensis from a specimen collected in the Hot- tentots Holland Mountains in the Cape Province, South Africa. Shortly after the des- cription of this new species, Dumeril and Bibron (1839) reinstituted the generic name Zonurus Merrem 1820 to replace Cordylus. Almost a century later Van Dam (1921)
