Diagnosis. Males are similar to those of C. lavras by having a very short embolus, but can be distinguished by more rectangular RTA and the median apophysis with a small acute projection on the concave margin (Fig. 17B–D) (bifid RTA and smooth concave margin of median apophysis in C. lavras, Fig. 16D–E). Females are similar to those of C. armasi by having an elongate median plate in the epigyne, but can be distinguished by having a wider median plate, and larger, deeper lateral depressions (Figs 17I, 18C, 26E–F) (narrower plate, smaller lateral depressions in C. armasi, Figs 19G–H, 26A–B).
