Aphantochilus is a small genus of ant-mimicking crab spiders from Central and 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. Individuals of A. rogersi have been observed carrying ant carcasses.
