Menemerus formosus is a species of jumping spider that was first described by Wanda Wesołowska in 1999.

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

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

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

[11] The species name derives from the Latin word formosus that means neat or shapely.

The spider has a very low brown clypeus that has a scattering of white hairs.

The spider has a large epigyne that is highly sclerotized and has a shallow depression and a furrow with a wide pocket.

[12] It has distinctive insemination ducts that have an unusual morphology, which are short and paired to accessory glands and to small spermathecae.

[15] The female is similar to Menemerus magnificus but differs in its one rather than two depressions in its epigyne.

[21] Menemerus spiders in the country live in groups in loose association with each other.

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