Gnathostenetroidoidea
Gnathostenetroidoidea is a superfamily of asellotan isopods established by Kussakin in 1967. Members are predominantly small crustaceans adapted to cryptic habitats, including both freshwater groundwater systems and marine interstitial environments. The superfamily includes families such as Protojaniridae and Caecostenetroididae. Documented species exhibit reduced or absent eyes and morphological specializations for subterranean or interstitial life.
