– Males (males of C. neethlingi spec. nov. and C. ukhahlamba spec. nov. unknown).................................. 6
2 Abdomen grey, with cream inverted Y-shaped marking dorsally (Fig. 10); epigyne with large circular depressions incorporating copulatory openings (Fig. 73)........................................................ C. ukhahlamba spec. nov.
– Abdomen uniformly grey dorsally, without marking (e.g. Fig. 3); epigyne with curved epigynal ridges incorporating copulatory openings............................................................................................ 3
3 Copulatory openings in anterolateral corners of faint M-shaped ridges (Fig. 54); bursae clearly much larger than primary spermathecae (Fig. 55)................................................................... C. capensis spec. nov.
– Copulatory openings in small C- or J-shaped ridges (e.g. Fig. 59); bursae same size or smaller than primary spermathecae (e.g. Fig. 60)............................................................................................. 4
4 Anterior margin of ridges incorporating copulatory openings in same transverse plane as anterior margin of primary spermathecae; initial 2/3 of copulatory ducts before posterior bend heavily sclerotized and darker than last 1/3 (Fig. 55)................................................................................................ C. infima comb. nov.
