The Holothyrida are a small order of mites in the superorder Parasitiformes.

It is divided into three families, Allothyridae, Holothyridae, and Neothyridae.

In a 1998 experimental study, members of the family Allothyridae were found to ignore living animals but readily fed on the body fluids of dead arthropods, making them scavengers.

[1] The order has a distribution largely confined to former Gondwanan landmasses.
