Identification
Cave-dwelling distinguished from by postantennal organ (PAO) with more than 5 lobes, contrasting with fewer than 5 lobes in other eyeless species. Eyeless condition combined with multi-lobed PAO indicates strong association with deep subterranean environments. Specific setal patterns on and furca provide species-level diagnostic characters.
Habitat
Deep subterranean caves; troglomorphic restricted to cave systems with stable microclimates.
Distribution
Documented from cave systems in Iran (Alborz Mountains) and Montenegro (Dinaric Karst); broader distribution likely includes additional cave systems in Palearctic region.
Behavior
of troglomorphic traits observed in geographically isolated , suggesting strong selection pressure in subterranean environments.
Human Relevance
Subject of biogeographic and evolutionary research; troglomorphic serve as indicators of subterranean isolation and evolutionary .

- Other Hypogastruridae generaSchaefferia cave distinguished by unique combination of eyelessness with PAO exceeding 5 lobes; other eyeless typically exhibit simpler PAO or different setal arrangements.
More Details
Taxonomic note
The name Schaefferia is also used for a of flowering plants (Celastraceae). The genus was established by Absolon in 1900 and is not related to the genus.
Recent discoveries
Two new described in 2025: S. greensladeae from Danial Cave, Iran and S. montenegrina from Babatuša Cave, Montenegro, representing first records of highly troglomorphic Schaefferia from these regions.
