Myrmecotypus is a genus of ant mimicking corinnid sac spiders first described by O. Pickard-Cambridge in 1894.[2] Species mainly occur from Panama to Mexico, with one species found in the United States, and one in Argentina.[3][1]

M. rettenmeyeri, named after entomologist Carl Rettenmeyer, has an unusual longitudinal band of black hairs extending along the midline of the cephalothorax, enhancing its resemblance to Camponotus sericeiventris, an ant it shares a habitat with. The black hairs correspond to the solid longitudinal keel-like dorsal extensions of the posterior sections of the ant's thorax.
