oa Annals of the Natal Museum - On the species of the genus Desis Walckenaer, 1837 (Araneae: Amaurobiidae) found on the rocky shores of South Africa and South West Africa

The morphological criteria used by authors to differentiate four species of Desis under revision are shown to be unreliable. An investigation of samples from a well studied single population revealed these criteria to be so widely variable as to bridge the particular character sets proposed for the various species. As a result of this, D. tubicola (Pocock), 1898, D. pentheri Simon, 1910 and D. beckeri Hewitt, 1913, are placed in synonymy of D. formidabilis (Cambridge), 1890.
