It is similar to other related species, particularly Langelurillus cedarbergensis, but can be distinguished by its closely-spaced copulatory openings and three-chambered receptacles.

Langelurillus namibicus is a jumping spider that was first described by the Polish arachnologist Wanda Wesołowska in 2011.

[5] In 2015, Wayne Maddison placed the genus in the subtribe Aelurillina, which also contained Aelurillus, Langona and Phlegra, in the tribe Aelurillini, within the subclade Saltafresia in the clade Salticoida.

[6] In 2016, Jerzy Prószyński placed the same genera in a group named Aelurillines based on the shape of the spiders' copulatory organs.

[8] The seminal ducts are short and lead to receptables that consist of three highly sclerotized globular chambers.

It most resembles Langelurillus cedarbergensis but differs in that the copulatory openings are closer together, the seminal ducts are longer and there are three receptacle chambers.
