Etymology: The specific name is a patronym in honor of Fernando PérezMiles, an important Uruguayan mygalomorph researcher who has contributed to the knowledge of theraphosid taxonomy.
Diagnosis: The female can be distinguished from all species in the genus, except C. fasciatus and C. elegans , by having four clear stripes on each side of the dorsal abdomen ( Fig. 46 View FIGURES 45 – 50 ). Differs from C. fasciatus by having the clear central patch covering less than 80% of the dorsal abdomen and from C. elegans by the central patch shape. The male can be distinguished from C. fasciatus , C. ritae , C. blenginii and C. sellatus by not having a retrolateral field of spiniform hairs on the palpal tibia. It differs from C. chicoi and C. nogueiranetoi new species by having a crested prolateral superior keel ( Figs 13, 14 View FIGURES 11 – 20 ) and by the presence of white stripes on legs. It differs from other species by having a long paraembolic apophysis.
