Distribution: To date, the species has been known only from South Africa (Wanless 1984 b; Wesołowska & Haddad 2009; present work).

Comments:The species has an easily recognizable epigyne, particularly the acute lobes of its rear edge and a pair of well-marked epigynal pockets (see Wanless 1984 b, figs 13 F, G). The samples examined by us contain both sexes collected together and therefore we are able to confirm the synonymy of C. armata Wesołowska, 2006  with C. lineata  proposed by Wesołowska & Haddad (2009; cf. Figs 6–9 and figs 3–5 in Wesołowska 2006).
