Evarcha mirabilis is a species of jumping spider that was first described by Wanda Wesołowska and Charles Haddad in 2009.

[1] It was one of over 500 species identified by the Polish arachnologist Wesołowska during her career, making her one of the most prolific in the field.

[4] In 1976, Jerzy Prószyński placed the genus was placed in the subfamily Pelleninae, along with the genera Bianor and Pellenes.

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

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

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

The palpal tibia has a projection with a very broad-base and sharp tip called a tibial apophysis.

The palpal bulb is rounded with a tegulum that a large lump near the bottom and a particularly short thin embolus.

For example, it has similarities with Evarcha patagiata, with which it shares the fact that its embolus is narrower than some spiders in the genus.

[13] Evarcha spiders live across the world, although those found in North America may be accidental migrants.
