''Saltonia incerta'' is a rare spider species, only known from California, USA, where it occurs on the shores of the Salton Sea, among salt-crusts in several dry or intermittent lake-beds, and from a small island in the Gulf of California. All of the few collected specimens were collected during March and April near salt springs, salt water or salt marshes. Its colulus is similar to that of two genera of intertidal zone spiders of the family Desidae, ''Paratheuma'' and ''Desis''. Genetic evidence suggests it is closely related to ''Paratheuma'' and the fully aquatic species ''Argyroneta aquatica''. Before it was placed into the family Dictynidae by Lehtinen in 1967, it was grouped under the family Agelenidae. Before that, it was at times considered to belong to the Clubionidae, thus living up to its species name ''incerta'' which is Latin for "uncertain". ==References== * Banks, N. (1898).
