a) Species-group: ferruginosa . Three species: C. ochracea, C. ferruginosa, and C. meridionalis .

Defined by symmetrical spiniform teeth on the posterior margin of the saccus (Pl. 14: Figs 1–3; see arrow Fig. 1). Other shared features include: i) male sternite VIII uniformly sclerotised with posterior margin acute V or Ushaped; ii) tegumen extended beyond articulation with saccus; iii) C-shaped tergal lobes projected posteriorly; iv) pseudotegumen expanded mesally and ribbed; v) valvae digitiform and longitudinally ribbed, and; vi) lateral plates of lamella antevaginalis with mesal corner not projecting, right angle or nearly so.

Distribution. Coastal uplands between Espírito Santo in southeastern Brazil and Rio Grande do Sul in southern Brazil at altitudes between about 450 and 1900 m. The three species are allopatric with marginal overlap between C. ochracea and C. meridionalis around Paraná and Santa Catarina borders (Pl. 25: Fig. 1).
