Langona pilosa is a species of jumping spider in the genus Langona that lives in Namibia. The male was first described by Wanda Wesołowska in 2006 and the female in 2011. The spider is small with a cephalothorax between 2.2 and 3.1 mm long and a abdomen between 2.1 and 3.5 mm. The female is larger than the male. 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 is a genus of spiders in the family Salticidae. Langona species are similar to those of the genus Aelurillus. In 2015, it was listed in the subtribe Aelurillina. The subtribe is allocated to the tribe Aelurillini in the clade Saltafresia. In 2017, it was grouped with nine other genera of jumping spiders under the name Aelurillines.
