Evarcha prosimilis

Evarcha prosimilis is a species of jumping spider that lives in Kenya, South Africa, Tanzania, Uganda and Zimbabwe.

It is ground-dwelling spider, thriving in leaf litter, but has also been observed living on the walls of houses and on grassy tussocks.

Evarcha prosimilis is a species of jumping spider, a member of the family Salticidae, that was first described by the arachnologists Wanda Wesołowska and Meg Cumming in 2008.

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

[8] In 2016, Jerzy Prószyński added the genus to a group of genera named Evarchines along with Hasarinella and Nigorella based on similarities in the spiders' copulatory organs.

[9] According to Maddison, Melissa Bodner and Karen Needham, the genus is closely related to the genera Hyllus and Plexippus.

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

[1][13] Evarcha prosimilis is a small spider with a body divided into two main parts: an almost rectangular oval cephalothorax and a larger and more rounded abdomen.

The underside is generally yellow or dark and marked with a pattern of small light dots making four lines running from front to back.

The pedipalps, sensory organs near the mouth, are brown with a scattering of white hairs on the palpal femur and the patella.

It is generally brown with an orange-brown thorax, which is darker at the edges, has grey hairs on its slopes and is marked by two white lines running towards the back.

It has specifically been found in leaf litter from Cussonia paniculata, Rhus lancea and Podocarpus trees.

[22] Evarcha prosimilis has been observed eating flies that are larger than itself, as well as long-jawed orb weaver spiders of the Metellina genus.

The spider will create a nest made of tightly woven layers of silk that is tubular and located close to the ground amongst creepers and leaves.

[23] Evarcha prosimilis is endemic to Africa, living in the semi-arid central and subtropical eastern and northern parts of the south of the continent.

[24] The first specimens of Evarcha prosimilis to be identified in South Africa were found in the Ndumo Game Reserve in 2002.

[25] Meanwhile, although they were not recognised as being part of the species at the time, examples of the spider had been discovered on Mount Elgon in Kenya as early as 1938.
