Menemerus paradoxus is characterised by its large epigyne that has a notch in its rear edge, the way that its copulatory openings are hidden in pockets and its heavily sclerotized spermathecae.

Menemerus paradoxus is a species of jumping spider that was first described by Wanda Wesołowska and Anthony van Harten in 1994.

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

[2] She allocated the spider to the genus Menemerus, first circumscribed in 1868 by Eugène Simon, which contains over 60 species.

[4] Genetic analysis has shown that the genus Menemerus is related to the genera Helvetia and Phintella.

[9] The vast majority of the species in Menemerines are members of the genus, with additional examples from Kima and Leptorchestes.

The eye field is very dark, almost black with a small number of brown bristles visible.

[11] For example, compared to the related Menemerus tropicus, the spider has a wider pocket in its epigyne and larger spermathecae.

[13] Menemerus spiders are found throughout Africa and Asia, and have been identified as far as Latin America.
