What are Whip Scorpions?

Whip scorpions are medium to large arachnids with large robust pedipalps, a pair of two-segmented chelicerae, four pairs of legs, of which the first pair are somewhat elongated, and a sub-rectangular abdomen terminating in a long multi-segmented flagellum. The common name whip scorpion is derived from the latter feature.

They are considered to be the sister-group to the schizomids (Schizomida) with which they share numerous features, such as the presence of repugnatorial abdominal glands.

Whip scorpions are mostly restricted to tropical and sub-tropical environments.



Unfortunately, there have been no phylogenetic studies on whip scorpions.


Fossil Fauna

Fossilised whip scorpions are derived from Palaeozoic and Mesozoic deposits. The four Palaeozoic genera (Geralinura, Parageralinura, Proschizomus and Prothelyphonus) have been found in Europe, Asia and North America, while the sole Mesozoic genus—Mesoproctus—derives from the Crato Formation in Brazil.
