It is very similar to other spiders in the genus, but differs in the shape of the male's tibial apophysis and the way that the female has both lobes at the back of the epigyne and short seminal ducts.

[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.

It has a dark brown carapace, rather high and covered with short white hairs, with a black eye field.

The pedipalps are brown and also very hairy, with a very convex tegulum with small toothlike appendages or spikes.

The spider has a broad epigyne with a strongly sclerotised plate on the back half and two distinctive lobes.

The particular, the female of the two species have a very similar epigyne but Langelurillus orbicularis is less sclerotised and lacks the two lobes.

Lobes can also be found on Langelurillus manifestus, but this species has much longer looping seminal ducts.
