f) Species-group: dorita .

Five species: C. dorita, C. verresi, C. danieli, C. forsteri, and C. zischkai .

All members share tapered,thumb-shaped or digitiform valvae, along with an anteriorly expanded pseudotegumen. In addition, by: i) fultura inferior about 1.0 to 1.5× longer than wide, slightly cup-shaped; ii) male sternite VIII rectangular and mesally notched posteriorly; iii) tegumen extended beyond articulation with saccus; iv) in the two species examined ( C. dorita and C. verresi), phallus as long as the genital apparatus with a rounded distal bladder, and; v) lateral plates of the lamella antevaginalis with mesal corner projected.

Distribution. Bolivia, northwestern Argentina, and the coastal and mainland between São Paulo in southeastern Brazil and Santa Catarina in southern Brazil at altitudes between about 800 and 2600 m. There are no records between these two main areas, indicating a disjunct distribution (Pl. 27: Fig. 1; Pl. 28: Fig. 1).

Remarks. Future examinations of the phallus will be critical to confirm the inclusion of C. danieli, C. forsteri, and C. zischkai in this species-group, but due to the Euparal preparations of the genitalia, this structure is not visible. Based on the shape of the valvae, the expansion of the pseudotegumen anteriorly, and the shape of the fultura inferior as stated above, they are provisionally assigned to this species-group.
