Diversity
10 species

Myrmecotypus is a spider genus that mimics ants. Species mainly occur Panama to Mexico, with one species found in the United States, and one in Argentina, suggesting distribution may be much wider than currently appreciated. M. rettenmeyeri has a strange longitudinal band of black hairs extending along the midline of the cephalothorax. This seems to enhance the resemblance to the ant Camponotus sericeiventris with which it shares the same habitat. The crests of black hairs correspond to the solid longitudinal keel-like dorsal extensions of the posterior sections of the ant's thorax.

M. rettenmeyeri is named after entomologist Carl W. Rettenmeyer, who researched ants.
