The male has a distinctive pedipalp with a complex tibial apophysis and a furrow alongside the femoral apophysis, which distinguishes it from the otherwise similar Asemonea maculata and Asemonea pinangensis.

Asemonea tanikawai is a jumping spider that was first described by Hiroyoshi Ikeda in 1996.

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

[3] Molecular analysis demonstrates that the genus is similar to Goleba and Pandisus.

[7] The spider is small, with a body length that can vary between 2.8 and 4.8 mm (0.11 and 0.19 in).

The carapace is covered in white hairs and marked with two brown stripes that stretch from the front to back.

The shape of apophyses on the dorsal tibia and femur on the male enable the species to be differentiated.

They spin sheet webs on the underside of leaves, where they also lay their eggs.
