Pseudicius sengwaensis is a jumping spider that was first described by Wanda Wesołowska and Meg Cumming in 2011.

[2] The genus name is related to two Greek words that can be translated false and honest.

[3] The genus was provisionally placed alongside Icius that, despite looking superficially similar, has a different etymology.

[10] Pseudicius sengwaensis is a small spider with an elongated body typical of the genus.

It has a flat oval, dark brown carapace covered in delicate hairs.

It is blackish with a pattern of eight white spots in pairs, similar to Afraflacilla venustula.

[10] The species differs from others in the genus in the shape of palpal bulb and the position of its embolus base.
