Identification
Identification to level requires examination of male genitalia and other fine morphological characters typical of the Travunioidea. Within Cladonychiidae, Speleonychia is distinguished from related genera by specific and somatic features established in the original description. The single known S. sengeri would be identified within the genus by species-level characters. Field identification to genus is not practical without specimen collection and microscopic examination.

Habitat
The type locality and known distribution in Washington state suggest association with moist forested environments of the Pacific Northwest. The name implies potential cave or subterranean usage, though this has not been explicitly confirmed in published sources.
Distribution
to Washington state, United States. The only confirmed records are from the type locality of S. sengeri.
