Genus Guides
1Brachystomellidae is a of springtails (Collembola) in the order Poduromorpha, established by Stach in 1949. The family comprises approximately nine extant plus one fossil genus, distributed across diverse global from tropical to polar regions. These hexapods are minute soil-dwelling arthropods belonging to the superfamily Neanuroidea. They are part of the lineage, characterized by mouthparts enclosed within the capsule.

Identification
Members of Brachystomellidae can be distinguished from other Poduromorpha by features of the mouthpart structure and body chaetotaxy (arrangement of setae), though specific diagnostic characters require microscopic examination. The family is placed in the superfamily Neanuroidea, separating it from the Poduroidea (which includes families like Poduridae and Hypogastruridae). Definitive identification to family level typically requires examination of the , , and structure.

Distribution
Global distribution spanning multiple biogeographic realms including: African Indian Desert region, Amazon basin, Andean region, Antarctic and Subantarctic islands, and the Antillean region plus southern Florida. This broad distribution suggests to varied climatic conditions from tropical to polar environments.
Similar Taxa
- PoduridaeAlso in Poduromorpha but in superfamily Poduroidea; differs in mouthpart structure and body form
- HypogastruridaeLargest in Poduromorpha, distinguished from Brachystomellidae by superfamily placement (Poduroidea vs. Neanuroidea) and specific chaetotaxy patterns
- NeanuridaeFellow member of Neanuroidea; requires microscopic examination of mouthparts and sensory structures for separation
