DIAGNOSIS: Males resemble those of C. penshurst (cf. figs. 366–372) but have a more sharply pointed distal embolar prong and a distally narrowed proximal prong (figs. 384–389); females have fully fused ventral scuta and resemble those of C. rafael (cf. figs. 144–154), but have a larger genital atrium and differently shaped posterior genitalic elements (figs. 391–394).
