First described in 2020 by Rudy Jocqué and Arnaud Henrard, the spider is small, measuring between 2.24 and 3.26 mm (0.088 and 0.128 in) in length.

[1] The species is named after the Polish arachnologist Wanda Wesołowska and its description was first published in a festschrift produced in her honour.

[4] Ranops wandae is a small spider and has the characteristic long legs of the genus.

The epigyne has a narrow plate in the middle, two chambers leading to stout spermathecae situated one above the other, with the top one larger.

[6] Like others in the genus, the spider has distinctive long legs, which are multiple times the body length.

Spiders in the genus also have, like some members of the Capheris and Systenoplacis genera, a wide sternum.

[7] Amongst the Ranops spiders, Ranops wandae can be identified by its copulatory organs, particularly the large median apophysis and the way that the retrolateral tibial apophysis is both shaped and extends from edge of the underside of the palpal bulb.

[10] This is close to the centre of distribution for the genus, located in semiarid areas of southern Africa.
