Isotomidae

Definition

A family of elongate-bodied springtails (Collembola) in the order Entomobryomorpha, characterized by slender, cylindrical bodies and generally well-developed furcula. Members are among the most abundant and widespread soil-dwelling Collembola, playing key roles in decomposition and nutrient cycling.

Etymology

Example

Isotoma viridis, a common Isotomidae species in temperate grasslands, feeds on fungal hyphae and contributes significantly to soil microbial community regulation.

Usage Notes

Distinguished from the similarly elongate Entomobryidae by details of chaetotaxy and body scaling; both families are often grouped informally as 'elongate' springtails in contrast to the globular Symphypleona. The family contains numerous genera and is cosmopolitan in distribution.
