COMMENT. The name Palpigradi has a senior synonym – Microthelyphonida, which is an available non-typified circumscriptional name. But Microthelyphonida resembles typifies names, such as Thelyphonida (i.e. Thelyphonus/fg); in order to avoid confusion between non-typified and typified names, it is more expedient to use the junior name Palpigradi as a valid one.
