4. Carapace with many small spines. Pseudorostrum long and prominent.......................... C. aculeata Jones, 1974
- Carapace with 16 stout spines (arranged in two longitudinal rows) and many small spines. Pseudorostrum short and strongly upturned......................................................................... C. spinosa Calman, 1906
5. Sides of the carapace without ridges, with shallow groove (sulcus)...............................................6
- Sides of carapace with two oblique ridges, with or without groove (sulcus)........................................ 8
6. Carapace without tubercles (only a blunt prominence on either side of the frontal lobe), long setae scattered over carapace dorsal surface........................................................................ C. pilosa Jones, 1974
- Carapace with numerous tubercles or prominences (verrucose aspect)........................................... 7
