Neelidae

Neelidae is a family of springtails in the order Neelipleona. There are at least 4 genera and more than 30 described species in Neelidae.

Genera
These four genera belong to the family Neelidae:
 * Megalothorax Willem, 1900
 * Neelides Caroli, 1912
 * Neelus Folsom, 1896
 * Zelandothorax Delamare Debouteville & Massoud, 1963

Description
Members of the family Neelidae are generally minute, averaging around 500 μm. They possess globular bodies superficially like that of the Symphypleona, with relatively long legs and a well-developed furca compared to other soil-dwelling springtails.

Phylogeny
Neelidae was initially considered to have a close affinity with Symphypleona, based on morphological characteristics shared between the two groups such as a globular shape, neosminthuroid setae and others. However, molecular data places them as a basal group to all other Collembola.
