Pseudicius wesolowskae is a species of jumping spider in the genus Pseudicius that lives in Hebei, China. The spider was first described in 2001 by Mingsheng Zhu and Daxiang Song. The spider is small, with a body length that is between 3.43 and 3.78 mm. The male is larger than the female. The spider has a light brown carapace with a black eye field. The abdomen is a dark brown on the top, marked by a pattern of white spots, and grey-yellow underneath, with a pattern of yellow-white spots. The copulatory organs enable the species to be distinguished from others in the genus. The male has a long embolus and unusual tibial apophyses. The female has a cross-shaped marking towards the rear of its epigyne. The species is named after the Polish arachnologist Wanda Wesołowska.

Pseudicius is a genus of the jumping spiders first described by Eugène Simon in 1885. The name is combined of Greek pseudo "false" and the salticid genus name Icius. The small genus Wesolowskana should possibly be included in this genus. There is some dispute whether Afraflacilla is a distinct genus or should be included in Pseudicius. Festucula and Marchena are other close relatives, these genera form a monophyletic group.
