The spider has a brown carapace that has two white stripes on its back, a large dark patch on its yellowish abdomen, a black eye field and the toothless chelicerae typical of the genus.

The male can be distinguished from others in the genus by the existence of tufts around the palpal bulb, after which it is named, and the very long and thin tibial apophysis.

The female has copulatory organs that resemble Langelurillus ignorabilis but differ in the design of the seminal ducts.

Langona pilosa is a jumping spider species first described by Wanda Wesołowska in 2006.

[5] It is particularly closely related to the genus Aelurillus, after which the subtribe, tribe and group are named.

The different Langona species generally cannot be distinguished from each other or from other members of the group by either their colours or the patterns that appear on their bodies, but by the structure of the copulatory organs.

The abdomen is yellowish with a large brown shell-like covering that takes up nearly two-thirds of the surface.

[9] The copulatory openings lead to relatively short and wide seminal ducts.

and there is a single apophysis, or appendage, on the pedipalp tibia, which enables it to be distinguished from other Aelurillinae.

[12] The male can be clearly identified by the design of its copulatory organs, are particularly the tuft after which it is named and length of the tibial apophysis.
