Japygidae

The Japygidae are a family of soil-dwelling insects belonging to the order Entotrophi. These primitive, wingless insects are characterized by their forceps-like anal appendages, rather than filamentous ones.1

Diplurans, which include the Japygidae family, are small, pale, and typically blind. They generally measure between 2 to 5 mm in length, though some tropical species can be larger. Diplurans inhabit soil and feed on decaying vegetation or other insects. The family Japygidae is one of the largest within the Diplura, with its members possessing cerci modified into pincers used for catching prey.2
