Bourletiella is a of springtails in the Bourletiellidae, suborder Symphypleona. These globular springtails are characterized by their rounded body shape and are among the most frequently observed genera, with over 3,000 iNaturalist records.

Identification
Members of Bourletiella can be distinguished from other Symphypleona by their globular body form with the , , and into a rounded mass. The is placed in Bourletiellidae, which can be separated from related families like Sminthuridae by specific chaetotaxy and antennal segment proportions, though -level identification requires microscopic examination of genital structures and setal patterns.

Taxonomic note
The class-level placement varies between sources: GBIF and NCBI list Collembola as a class, while iNaturalist places springtails in class (subclass) within Hexapoda. The suborder Symphypleona represents one of the three major lineages of springtails, characterized by the globular body form distinct from the elongate Entomobryomorpha and Poduromorpha.
Observation frequency
With 3,019 iNaturalist observations, Bourletiella is among the most frequently documented , likely reflecting both genuine abundance and relative ease of photographic identification to genus level due to its distinctive globular .
