Neelipleona

Definition

A group of minute, eyeless springtails (Collembola) comprising the family Neelidae, variously ranked as a suborder or order within the class Collembola. Members are characterized by their globular body form, reduced mouthparts, and absence of ocelli and compound eyes; they occupy interstitial spaces in soil and leaf litter. The rank has been unstable in springtail taxonomy, treated historically as order, suborder, or infraorder depending on classification scheme.

Etymology

From the family name Neelidae (after the French entomologist Neel) + Greek pleion (more, greater), with suffix -ona indicating a ranked group; coined by Massoud, 1971.

Example

The springtail Megalanura is classified within Neelipleona, reflecting its eyeless condition and rounded body shape distinct from the elongate Entomobryomorpha and the globular but eyed Symphypleona.

Synonyms

• Neelida (obsolete rank variant)

Related Terms

• Collembola
• Symphypleona
• Entomobryomorpha
• Poduromorpha

• Edaphic
• interstitial fauna

Usage Notes

Rank is unstable: GBIF treats Neelipleona as order, while most modern systems place Neelidae within Symphypleona or as sister to it; specialists should verify the classification scheme in use. The group is small (fewer than 50 described species) and frequently overlooked in soil fauna surveys due to minute size.
