Actaletidae

Definition

A family of springtails (Collembola) in the order Entomobryomorpha, comprising elongate, slender-bodied species typically found in moist terrestrial habitats. Members of this family are distinguished from other entomobryomorphs by features of the mouthparts and body setation, and they represent one of the more species-rich families within this major springtail lineage.

Etymology

From the type genus Actaletes (Greek aktē, 'coast' or 'shore' + suffix -etes, 'dweller'), with the family suffix -idae.

Example

Species in Actaletidae, such as those in the genus Actaletes, are commonly collected in leaf litter and soil samples from temperate forests, where they contribute to decomposition and nutrient cycling alongside other Collembola families like Entomobryidae.

Related Terms

Usage Notes

Actaletidae is one of several families within Entomobryomorpha, the largest order of springtails; it is distinguished from the closely related Entomobryidae and Paronellidae by subtle morphological characters that require microscopic examination. The family is sometimes overlooked in ecological surveys due to the taxonomic challenges of identifying small, pale entomobryomorphs to family level.
