The Entomobryomorpha are one of the three main groups (order) of springtails (Collembola), tiny hexapods related to insects.

They either have short legs and antennae, but their long bodies set them apart, or long legs and antennae, as well as well-developed furculae; these are the most characteristic members of the order.

Actually, the Entomobryomorpha, the Poduromorpha, and the third springtaill lineage – the Symphypleona – are equally distinct from each other.

When the springtails were still believed to be an order of insects, the "Arthropleona" and the Symphypleona were treated as suborders.

[2] The review abolishes the former "Actaletoidea", which is apparently paraphyletic; its namesake family is now placed in the Isotomoidea, while the Coenaletidae form a new monotypic superfamily.
