Pseudicius mirus is a jumping spider that was first described by Wanda Wesołowska and Antonius van Harten in 2002.

[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.

[4][5] Indeed, Ekaterina Andreeva, Stefania Hęciak and Jerzy Prószyński looked to combine the genera in 1984.

[6] The two genera have similar spermathecal structure but work by Wayne Maddison in 1987 demonstrated that they have very different DNA.

It is oval, widest towards the middle with a flattened forward part, and covered in dense short white hairs.

Dense white hairs cover much of the copulatory organs, which are unusual and so help distinguish the species from others in the genus.

The embolus is short and blunt.There are two tibial apophyses, one with a small hook jutting out from it, the other more blunt.
