Sinella cavernarum
(Packard, 1888)
Cavernicolous springtail
Sinella cavernarum is a of in the , first described by Packard in 1888. The species epithet 'cavernarum' (of caves) suggests a troglophilic or troglobitic lifestyle. As an springtail, it possesses the characteristic elongated body form and well-developed typical of this group. Very few observations of this species exist in public databases.

Identification
Distinguished from poduromorph by its elongated body and relatively long . Within , Sinella generally lack the distinctive color patterns and heavy pigmentation seen in some related like Entomobrya. The specific identification of S. cavernarum would require examination of (bristle arrangement) and other microscopic characters, as visual identification from photographs is generally unreliable for this genus.
Habitat
The epithet and suggest association with cave environments, though specific details remain poorly documented.
Distribution
Southern North America based on GBIF records; precise range boundaries unknown.
