Pseudicius ridicularis is a jumping spider that was first described by Wanda Wesołowska and Beata Tomasiewicz in 2008.

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

[9] The species name is based on a Latin word that refers the unusual "grotesque" shape of the appendage on the palpal tibia.

The epigyne has two rounded centrally-located copulatory openings and a wide pocket in the epigastric furrow.

There are small accessory glands that lead to insemination ducts and strongly sclerotised elongated spermathecae.

The spider has a very large tibial apophysis that has a distinctive bend to the tip and a short thick embolus.

The male has a particularly large and bent tibial apophysis and the female longer receptacles than others in the genus.
