Professor Wilson Lourenco has published an interesting review on parthenogenesis in scorpions. This is a rare phenomenon in arachnids, but so far parthenogenesis has been reported in 12 scorpion species:
Tityus columbianus (Thorell, 1876)
T. metuendus Pocock, 1897
T. serrulatus Lutz & Mello, 1922
Tityus sp. [New sp. not yet described - info in the article]
T. stigmurus (Thorell, 1876)
T. trivittatus Kraepelin, 1898
T. uruguayensis Borelli, 1901
Ananteris coineaui Lourenco, 1982
Centruroides gracilis (Latreille, 1804)
Hottentotta caboverdensis Lourenco & Ythier, 2006
H. hottentotta (Fabricius, 1787)
Liocheles australasiae (Fabricius, 1775)
Professor Lourenco discuss the general theory behind parthenogenesis in animals, compare these to the situation seen in scorpions, and finally presents some selected examples of geographic parthenogenesis in scorpions.
