Aphantochilus is a small genus of ant-mimicking crab spiders from Central to South America.
The three known species mimic ants of the genus Cephalotes (probably C. atratus), which are their preferred prey.
A. rogersi is a polymorphic mimic: some individuals use C. atratus as a model species, while others resemble C. pusillus. It also carries dead ants. source
