Diagnosis. Males are similar to those of C. armasi by having a retrobasal cymbial horn, but can be distinguished by having a more elongate median apophysis, the slightly longer embolus, with sulcated embolus tip, and presence of the thick bent macroseta on the dorsum of the male palpal tibia (Figs 21C–E, 22B–D) (shorter embolus and thicker median apophysis with mesal tooth in C. armasi, Fig. 20F).
