Zodarion wesolowskae

Only the male has been described, although Benhalima and Bosmans suggest that the female could be one of the spiders described as Zodarion trianguliferum.

The spider is a member of the mostafai group within the genus, which lack a tooth at the end of the embolus.

[4] RAD sequencing has demonstrated that it is one of the oldest of the extant spider genera, dating to the Cretaceous–Paleogene boundary.

The embolus lacks a tooth, similar to other members of the mostafai group, but the very long tibial apophysis is unusual and can help identify the species.

[12] Zodarion spiders are known to mimic ants for both defensive purposes and to surprise prey.

In three-quarters of observed encounters with ants, the spiders were successful in their deception, and even when not, would frequently attempt to distract their prey and attack from behind.

[15] Their success in devouring specific types of ants has led to the proposal to use these spiders as biological pest controls.

[1] It has only been found near the source of the Oum Er-Rbia River in the north of the Khénifra Province.
