The male Evarcha denticulata has a distinctive tooth on the spike, or apophysis, that emanates from its palpal tibia, which is recalled in the specific name.

Evarcha denticulata is a species of jumping spider, a member of the family Salticidae, that was first described by the arachnologists Wanda Wesołowska and Charles Haddad in 2013.

[5] In Wayne Maddison's 2015 study of spider phylogenetic classification, the genus Evarcha was moved to the subtribe Plexippina.

[11] This designation is not widely accepted and the species remains in the Evarcha genus in the World Spider Catalog.

The spider's body is divided into two main parts: a rather rounded almost rectangular cephalothorax and more pointed and ovoid abdomen.

The spider's carapace, the hard upper part of the cephalothorax, is high and generally male is with a lighter brown flat patch in the middle.

It is also blackish-brown on top with a pattern of white hairs forming a streak along the front edge and a band across the middle broken up by large spots to the rear.

The spider is similar to the related Evarcha vittula but can be distinguished by the shape of the tibial apophysis and the T-shaped marking on its abdomen.

There are blackish areas and white patches near the eyes, the hairs that form the latter radiating in lines down the slopes of the carapace.

The two copulatory openings lead to relatively short and wide insemination ducts and spermathecae or receptacles that have thick walls and strong sclerotization.

[1] The male holotype was discovered on a grassy tussock 10 km (6.2 mi) from Paterson in Eastern Cape in 2011.

Other examples have been found in urban areas like Cape Town and at high altitudes in the Amathole Mountains, typically at a height of 1,270 m (4,170 ft) above sea level,[19] The first female specimen to be identified was found in Fisherhaven in 2004 and subsequently in areas like Jeffrey’s Bay as well as the Amathole Mountains.
