Kingdom: Animalia
Phylum: Arthropoda
Subphylum: Hexapoda
Class Entognatha
Subclass: Collembola
Order: Poduromorpha
Common name: Springtails.

The order Poduromorpha is one of the three main groups of springtails (Collembola), tiny hexapods related to insects. This group was formerly treated as a superfamily Poduroidea.
They can be best distinguished from the other springtail groups by their body shape.
The Symphypleona are round animals, almost spherical. 
The Entomobryomorpha contain the slimmest springtails, some with long and some with short legs and antennae, but always with a very slender body. 
The Poduromorpha, by contrast, always have short legs and a plump body, but more oval in shape than the Symphypleona
