Japygidae

The japygids (family Japygidae) are a taxon of hexapods, of the order Diplura, commonly known as forcepstails.

In this family, the paired cerci at the end of their abdomens are pincer-like (superficially similar to the unrelated earwigs) and are used to catch their tiny prey. Seventy genera are recognised, divided among seven subfamilies.
