Pseudicius wesolowskae is a jumping spider that was first described by Mingsheng Zhu and Daxiang Song in 2001.

[1] They allocated the species to the genus Pseudicius, first raised by Eugène Simon in 1885.

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

[4][5] The two genera have similar spermathecal structure but work by Wayne Maddison in 1987 demonstrated that they have very different DNA.

[9] The spiders have flattened and elongated body and characteristic colour patterns.

[12] It has a flat light brown carapace scattered in short white hairs and spines, with black edges.

The chelicerae is lighter with two teeth at the front and one to the rear and the eye field is black.

[13] There long curved insemination ducts that lead to strongly sclerotised oval spermathecae.

There are two spines on the back tibia and the tibial apophyses consist of two fork-like appendages, one with ridges lining one side.

It can be distinguished by the male's small embolus and the female's cross-shaped marking towards the rear of the epigyne.

[12] It was found in Zhuolu County in 2004 and has a species distribution across the province of Hebei.
