Figs 21–22 , 27 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 ).
