Sminthuridae

Sminthuridae is a family of springtails of the order Symphypleona. Sminthurids are commonly referred to as globular springtails.

Description
Like other Symphypleona, Sminthuridae are globular in shape and have a furcula that allows them to jump. Members of this family have four-segmented antennae in which the basal segment is short and the rest successively increase in length. The terminal antennal segment has about 20 whorls of hairs and is divided into numerous subsegments. Sminthuridae also have well-developed tracheae. The dens has many setae, unlike in Mackenziellidae where it has 3 setae. Females have subanal appendages.

Ecology
Sminthuridae occur in surface litter layers, on vegetation and in tropical forest canopies. They may be collected using Tullgren funnels or pitfall traps, or by sweeping through grass with a pan. Additionally, Sminthuridae is one of the springtail families that includes species living in freshwater.
