j) Species-group: olinda .

Six species: C. babi sp. nov., C. clara sp. nov., C. kika sp. nov., C. parana sp. nov., C. piacaba sp. nov., and C. olinda sp. nov.

The principal defining feature of this group is the separation of inner and outer walls of the saccus, producing an external bag, a unique condition within the genus. The inner wall articulates with the fultura inferior. The group can also be recognized by: i) male sternite VIII trapezoidal, uniformly sclerotised, and the posterior margin concave; ii) tergal lobes arcuate, with or without projection; iii) tegumen extended beyond the articulation with saccus; iv) pseudotegumen not ribbed, expanded anteriorly and conspicuously projected ventrally and curved outwards distally; v) valvae spoon-shaped, setose, and not ribbed; vi) fultura superior always present, sometimes softly sclerotised, and; vii) lamella antevaginalis with mesal portion fused, laterally with processes.

Distribution. Coastal between Minas Gerais in southeastern Brazil and northeastern Santa Catarina in southern Brazil, at altitudes between about 500 and 1900 m (Pl. 29: Fig. 1).

Remarks. Within this group, there are two subgroups. The first, composed by C. babi sp. nov., C. clara sp. nov., and C. parana sp. nov., where the outer margin of the saccus is not notched posteriorly, valvae are basally concave, not reinforced, blade-shaped distally, and two ventro-anterior and two ventro-posterior diverticula in the phallus. The second, composed by C. kika sp. nov., C. piacaba sp. nov., and C. olinda sp. nov., has the outer margin of the saccus notched, deeply invaginated posteriorly, and valvae basally concave, reinforced, stout distally, and with a single ventro-anterior and two ventro-posterior diverticula in the phallus.
