Speleonychia
Speleonychia is a genus of armoured harvestmen (Opiliones: Laniatores) in the family Cladonychiidae, established by Briggs in 1974. The genus contains at least one described species, S. sengeri, which is endemic to Washington state in the northwestern United States. As a member of the Travunioidea superfamily, it belongs to a group of small, often cryptic harvestmen associated with moist microhabitats. The genus name suggests a cave-associated or subterranean lifestyle, though specific ecological details remain poorly documented.
