It mimics ants, living alongside and preying upon them, particularly Camponotus detritus.

It is similar to others in the genus, but can be distinguished by the dark pattern on its abdomen, consisting of a stripe to the front, two patches in the middle and black chevrons at the back.

Mexcala namibica is a jumping spider that was first described by the Polish arachnologist Wanda Wesołowska in 2009, one of over 500 species she identified during her career.

[2][3] The genus was a member of the tribe Heliophaninae alongside Pseudicius and Cosmophasis, which was absorbed into Chrysillini by Wayne Maddison in 2015.

[9] The female has a blackish carapace that has a covering of brown hairs and is typically 3.3 mm (0.13 in) long.

[10] Like other jumping spiders, it is mainly a diurnal hunter that uses its good eyesight to spot its prey.

[14] It uses visual displays during courtship and transmits vibratory signals through silk to communicate to other spiders.
