Euophrys cochlea is a species of jumping spider in the genus Euophrys that is endemic to South Africa. The species was first described in 2014 by Wanda Wesołowska, Galina Azarkina and Anthony Russell-Smith. It is a medium-sized brown spider, with a body that consists of a cephalothorax that is between 1.7 and 2.4 mm (0.07 and 0.09 in) long and an abdomen between 1.7 and 2.9 mm (0.11 in) long. The cephalothorax has a dark brown carapace, or topside. The spider's eye field is darker, with black rings around the eyes but marked with a white patch. The female has a yellowish-brown abdomen while the male is a darker brown. While the female has light brown to yellow legs, the male's legs whitish-yellow or yellowish-orange. The spider is most easily differentiated from others species in the genus by its screw-like embolus, part of the male's copulatory organs. This is recalled in the species name, the Latin word for screw.
