Weygoldtina is an extinct genus of tailless whip scorpion known from Carboniferous period, and the only known member of the family Weygoldtinidae.

While describing the British species, Graeophonus anglicus, Reginald Innes Pocock noted significant differences between the Nova Scotian and more complete Mazon Creek fossils.

[4] Graeophonus anglicus has been found in the English Middle Coal Measures of Coseley, Staffordshire.

[5] However, in 2018, researchers considered that the genus Graeophonus is invalid, because the holotype specimen of G. carbonarius (=Libellula carbonaria) is poorly preserved and hard to identify as an amblypygid.

[2] The center of the dorsal shield has a deep depression which probably acted as an attachment site for the muscles of the sucking stomach.

While Paracharon is notably blind, this is thought to be a secondary result of living almost exclusively within termite mounds.

Paleoamblypygi is a monophyletic suborder that contains Paracharon, Weygoldtina, in addition Paracharonopsis cambayensis that is described from Eocene Cambay amber.
