Georissa is a genus of minute snails, terrestrial gastropod mollusks in the family Hydrocenidae. Although the species are best known for living on the surface of limestone rocks, they are often also found in and on the vegetation and on non-calcareous rocks. One species, G. filiasaulae, is cavernicolous. It is only known from two caves in the Sepulut area of Sabah, Malaysian Borneo, where its above-ground sister species, G. saulae, inhabits the rocks outside of the cave.[2]
