A new eyeless troglobite scorpion, Akrav israchanani n. sp., is described from inside karstic voids in Israel that form a completely isolated, old underground ecosystem with living populations of blind crustaceans and pseudoscorpions. The scorpions, of which no live specimen has yet been collected, prove to differ from all other scorpions and are placed in a new family, Akravidae. The possibility is addressed that the subterranean Akravidae are a relict of an old circum-tropical pattern of distribution that differs from the present temperate location of Israel.
