Myrmarachne formicaria
It is the only ant-like North American jumping spider in which the male chelicerae project forward more than 50% of the carapace length, and in which the female palpal tarsus is dorsoventrally flattened and bent downward distally. (Bradley et al. 2006)
The species appears to be fairly common and is active during the warm months of the year in open areas as well as in buildings. It is sometimes associated with the local ants of the genus Formica. (Bradley et al. 2006)
