The Holothyrida are a small order of mites in the superorder Parasitiformes. No fossils are known. With body lengths of more than 2 mm (3⁄32 in) they are relatively large mites, with a heavily sclerotized body. 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.[1]
The order has a distribution largely confined to former Gondwanan landmasses. They are the sister group to Ixodida (ticks).[2]
