Mackenziellidae

Definition

A family of springtails (Collembola) in the order Symphypleona, characterized by a globular body form and reduced furcula. Members of this family are distinguished from other symphypleonan families by subtle differences in antennal segmentation, mouthpart structure, and chaetotaxy. The family was established by Yosii in 1961 and remains one of the smaller, less frequently encountered families within the globular springtails.

Etymology

Example

Specimens of Mackenziellidae are rarely collected in standard soil extractions due to their preference for specific microhabitats such as moss cushions and decaying wood in temperate forests; identification requires slide-mounting to examine the diagnostic features of the mouth cone and antennae.

Usage Notes

A small family of limited species diversity; field workers typically encounter Mackenziellidae only in specialized microhabitat sampling. The family is distinguished from the more common Sminthuridae and Katiannidae by detailed morphological characters visible only under high magnification. The type genus is Mackenziella.
