It is distinguished from similar spiders, like Langelurillus difficilis, by its complicated epigyne with its long spiralling seminal ducts.

[6] 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.

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

[8] The species is named after a Latin word that means terrible and relates to the complicated structure of the epigyne.

[11] The female holotype was collected on the road to Bakoré in the Guinea Highlands in 1956, at an altitude of 500 m (1,600 ft) above sea level.
