Beetle-mimic jumper
Jumping spiders not only mimic ants, but sometimes beetles.
In case the reason for mimicking a beetle is not clear, it is because beetles have hard wing covers for protection while spiders are soft, so some predators are presumably deterred by the inconvenience of a crunchy coating. Whatever the reason for the disguise, it seems to work as these are not terribly uncommon spiders. ~ Austin Bug Collection
