Strumigenys is a genus of ants in the subfamily Myrmicinae.

Strumigenys form small nests in soil, under or between rocks, or in and under logs or under cattle dung.

Some species nest in association with other ants such as Bothriomyrmex mayri or Rhytidoponera metallica.

[citation needed] S. xenos is a permanent social parasite, which forms no workers and lives in the nests of its host S.

[citation needed] Most species specialize in the hunt of springtails, and the others eat other soft-bodied arthropods.
