It lives in loose conglomerations in nests of white papery silk and is particularly visible in September and October.

The legs are generally yellow, apart from the front pair on the male, which are brown, longer and stouter and used for stridulation.

Both have a distinctive iridescent patch at the back of the abdomen that is recalled in the name of the species, which is a Latin word that can be translated "brilliant".

It is this iridescent patch that helps to distinguish the species, although a study of the copulatory organs is needed to confirm its identity.

Originally allocated to the genus Pseudicius, it was moved to its current name by Jerzy Prószyński in 2016.

[3] First circumscribed by Eugène Simon in 1885, the genus Pseudicius is named after two Greek words that can be translated false and honest.

[7] In 2016, Jerzy Prószyński moved the species to the genus Afraflacilla on the basis of the shape of the spider's copulatory organs.

[9] Members of the group of genera can be distinguished from other jumping spiders by their stridulatory spines and their copulatory organs.

It is very dark brown, nearly black, on its front of the topside and yellowish to the rear with a pattern of four small round white patches in pairs.

It is a brown elongated oval marked with a few small white patches in pairs and a similarly iridescent area towards the rear as the female.

The pedipalps are brown.The palpal femur is slightly swollen and the tibia is short with a wide protrusion, or apophyses.

[8] The iridescent patch on the rear of the abdomen is its most distinctive feature but a study of the design of the copulatory organs enables the identity of the species to be confirmed.

For example, the male being distinguished from Afraflacilla elegans by its wider and shorter tibial apophyses and the shape of its embolus, particularly the broad base.

They will create summer and winter retreats, the latter thicker with a sticky silk that fully covers the spider.

[3] It lives particularly on tree trunks, using the small gaps formed when pieces of bark detach as hiding places and as locations for its nests.
