Sminthurides aquaticus, copyright Andy Murray.

Belongs within: Collembola.
Contains: Katiannini, Sminthurini, Bourletiellini.

The Sminthuridae are a family of globular springtails in which the antennae are elongate, with the distalmost segment equal to or longer than the penultimate segment. Most species are epigaeic, living in or on leaf litter or on low vegetation (Greenslade 1991).

In members of the subfamilies Sminthuridinae and Katianninae, the corpus of the retinaculum bears lateral appendages at the base of the rami; such appendages are absent in Sminthurinae. Sminthuridinae have the anal and genital segments fused whereas these segments are separated in Katianninae (Womersley 1939). Members of the tribe Spinothecini, found in South America and Australasia, have a pair of sacs encircling the neck (Greenslade 1991).
