Proisotominae is a subfamily of elongate-bodied springtails in the family Isotomidae. There are about 7 genera and more than 190 described species in Proisotominae. [1] [2]
 
 These seven genera belong to the subfamily Proisotominae:

The subfamily Neanurinae contains pudgy short-legged springtails of the order Poduromorpha. It was established by Carl Börner in 1901 – or rather, it is the result of taxa being split out of Börner's family whereas the type genus and its closest relatives were retained here.

Paronellidae is a family of elongate-bodied springtails in the order Entomobryomorpha. There are about 18 genera and at least 90 described species in Paronellidae.

Brachystomellidae is a family of springtails in the order Poduromorpha. There are about 9 genera in Brachystomellidae.

Hypogastruroidea is a superfamily of springtails in the order Poduromorpha. There are at least 2 families and more than 700 described species in Hypogastruroidea.
Pachytullbergiidae is a family of springtails in the order Poduromorpha. There are at least two genera and four described species in Pachytullbergiidae.

Tullbergiidae is a family of springtails in the order Poduromorpha. There are more than 30 genera and 120 described species in Tullbergiidae.
Caputanurininae is a subfamily of springtails in the family Neanuridae. There are at least two genera and at least one described species, Caputanurina sinensis, in Caputanurininae.
Morulininae is a subfamily of springtails in the family Neanuridae. There are at least 2 genera and about 11 described species in Morulininae.

Pseudachorutinae is a subfamily of springtails in the family Neanuridae. There are more than 50 genera and 200 described species in Pseudachorutinae.

Sminthurides is a genus of globular springtails in the family Sminthurididae. There are more than 30 described species in Sminthurides.

Sminthurididae, not to be confounded with: Sminthuridae, is a family of globular springtails in the order Symphypleona. There are about 5 genera and more than 40 described species in Sminthurididae.
