[3] It was listed in the subtribe Aelurillina in the tribe Aelurillini by Wayne Maddison in 2015.

[4] In 2017, the genus was grouped with nine other genera of jumping spiders under the name Aelurillines.

[5] The name of the species is based on a Latin word meaning winding, and relates to the meandering shape of the seminal ducts.

The black eye field has dense grey hairs and short bristled.

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

[7] 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.

[8] The species resembles the related Langona pilosa, but may be identified by the shorter apophysis on the tibia in the male and longer seminal ducts in the female.

[9] Langona tortuosa is found in Namibia, South Africa and Zimbabwe.

[1] The holotype was found in 1987 in Caprivi, about 26 kilometres (16 mi) west of Kongola, Namibia.
