The female has spines on its palpal tibia and a distinctive epigyne that with a complex internal structure with helical receptacles.

Asemonea flava is a jumping spider that was first described by the Polish arachnologist Wanda Wesołowska in 2001, one of over 500 species she identified during her career.

[1][2] The species was allocated to the genus Asemonea, first raised by Octavius Pickard-Cambridge in 1869.

[8] The epigyne is an oval with a large depression towards the front and a raised part towards middle.

The seminal ducts are initially very wide, narrowing as the wend their way to the receptacles, which are a complex of coiled helixes.

[1] The holotype was found on Mount Elgon in 1937 at an altitude of 2,350 m (7,710 ft) above sea level.
