Distribution. This species was previously recorded from Namibia ( Johnsen 1990 b; Naskrecki 1995) and South Africa ( Dirsh 1956b)

Remarks. This genus was erected by Uvarov (1922), on the basis of its head integument, pronotum and the degree of development of the lateral carinae. Dirsh (1956) reviewed the genus and found that Uvarov’s (1922) generic characters are misleading because those generic characters vary between and within species.

I found a great deal of diversity in the shape and rugosity of its pronotum when I reviewed museum and field collected specimens. This also supports the statement by Dirsh (1956) that those characters (dorsum rugosity and shape) are misleading as they vary within species. The taxonomic status of this genus is not satisfactory and the genus has approximately four undescribed species, therefore revision is necessary.
