From C. patagonica and C. sanjuanina, females differ also in the patterned cephalothorax and legs. DescriptionThe female has a total length of {{convert|8.4|mm|in}}; a cephalothorax length of {{convert|3.02|mm|in}} and width of {{convert|2.55|mm|in}}; a cephalic region length of {{convert|1.87|mm|in}} and width of {{convert|1.85|mm|in}}; a fovea width of {{convert|0.37|mm|in}}; an OQ length of {{convert|0.34|mm|in}} and width of {{convert|0.61|mm|in}}; a labium length of {{convert|0.29|mm|in}} and width of {{convert|0.67|mm|in}}; and a sternum length of {{convert|1.71|mm|in}} and width of {{convert|1.42|mm|in}}. Its cephalic region is convex; the fovea is slightly procurved. The labium possesses no cuspules. A serrula is absent; the sternal sigilla is small and shallow; the sternum is rebordered. Its cephalothorax is yellowish brown; the legs are of the same colour, but lighter; it carries darker spots on its cephalic region, on the retrolateral apex of the femora, the middle of the patellae, and the base of the tibiae.[1] See also
