Superfamily Aselloidea (Waterslaters)
2 families, both in our area. Stenasellidae only contains 2 species in our area and both are small-ranged stygobionts in FL and TX
Family identification in Asellota is fairly simple: Asellidae has the pleonites small and ring-like, usually forming a narrow poorly visbible "pedicel" to the telson, while Stenasellidae has much larger pleonites that are always visible and often reach the margins. Stenasellids are also all stygobionts, so any heavily pigmented eyed waterslaters you find on the surface will always be Asellidae
