Spelaeogriphacea is an order of crustaceans that grow to no more than 10 millimetres (0.39 in). Little is known about the ecology of the order. [1]
Only four species, all subterranean, have been described. Of the three genera, Potiicoara is known only from a cave in Brazil's Mato Grosso, Spelaeogriphus only from a cave on Table Mountain in South Africa, and the two Mangkurtu species only from individual Australian aquifers. [1] Fossils of the group are known from the Early Carboniferous of Canada ( Acadiocaris) and the Early Cretaceous of Spain ( Spinogriphus, Las Hoyas) and China ( Liaoningogriphus, Yixian Formation), which are assigned to the family Acadiocarididae.
