Evarcha certa is a species of jumping spider in the genus Evarcha that lives in Guinea and Ethiopia. It thrives in grasslands, particularly near bodies of water like the Baro River and in areas of high altitude such as the Guinea Highlands. The species was first described in 2002 by Christine Rollard and Wanda Wesołowska. The spider is small, with a cephalothorax measuring between 2.6 and 2.9 mm (0.10 and 0.11 in) long and an abdomen that is between 2.7 and 3.4 mm (0.11 and 0.13 in) long. The cephalothorax has a reddish-brown topside, or carapace, with a darker eye field, and an orange underside, or sternum. The abdomen has a pattern consisting of irregular brown patches, although this differs between individual spiders. The spider has orange or yellow legs. It has distinctive copulatory organs. The female has relatively simple spermathecae that are heavily sclerotized and short insemination ducts. The male has not been described.
