Suborder IOCHEIRATA Harvey, 1992

Compiler and date details

Mark S. Harvey, Western Australian Museum, Perth, Western Australia, Australia


The suborder Iocheirata was established by Harvey (1992) to include those pseudoscorpions with a venom apparatus within at least one chelal finger. This group contains the vast majority of pseudoscorpions, with more than 2,500 species worldwide placed in nearly 400 genera. The suborder is currently divided into two infraorders, the Hemictenata and the Panctenata (Harvey 1992), both of which are strongly represented in the Australian fauna.



Members of the suborder Iocheirata possess a venom apparatus in the fingers of the chelae, with the venom discharging through the tips of the fingers. The plesiomorphic condition for the Iocheirata appears to be venom apparatus in both fingers, but many different groups have lost the venom gland in either the fixed or the movable finger.
