Psoroptidia is a suborder of the Acari (mite) group Astigmatina. It comprises around 40 families, and apparently originated as parasites of birds, before a secondary radiation saw some taxa become parasites of mammals. Because of their parasitic lifestyle, members of the Psoroptidia do not exhibit a deutonymph stage.
