It is a jumping spider that is endemic in Kenya first described in 1994 by Maciej Próchniewicz, the species name denoting its position as first to be identified.
The male has three tibial apophyses, or spikes, a short pointed embolus and a large ovoid tegulum.
[1] Próchniewicz allocated it as the type species of the genus Langelurillus, raised at the same time.
[2] In 2015, Wayne Maddison listed the genus in the subtribe Aelurillina, which also contains Aelurillus, Langona and Phlegra, in the tribe Aelurillini, within the subclade Saltafresia in the clade Salticoida.
[4] In 2016, Jerzy Prószyński placed the same genera in a group named Aelurillines based on the shape of the spiders' copulatory organs.
The yellowish-green abdomen is typically 1.95 mm (0.077 in) long has a pattern of greyish spots its back and rectangular scutum.
The epigyne is very small and has a single pocket and long tube-like seminal ducts that lead to multi-chambered and highly sclerotised oval spermathecae.
[9] The related Langelurillus krugeri can be identified by its shorter seminal ducts and the way that the spermathecae are placed perpendicular, rather than parallel, to the epigastric furrow.
