Parasitiformes are a superorder of Arachnids, constituting one of the two major groups of mites, alongside Acariformes. Parasitiformes has, at times, been classified at the rank of order or suborder.
Opilioacaridae is the sole family of mites in the order Opilioacarida, made up of about 13 genera. The mites of this family are rare, large mites, and are widely considered primitive, as they retain six pairs of eyes, and abdominal segmentation. They have historically been considered separate from other mites belonging to Acariformes and Parasitiformes, but are now generally considered a subgroup of Parasitiformes based on molecular phylogenetics.
Prostomidae is a family of beetles with no vernacular common name, though recent authors have coined the name jugular-horned beetles. They are often found in dead wood. The family consist of two extant genera with about 20 species. Prostomis americanus is known from North America. Other species of Prostomis are found in Europe, Africa, the Pacific region and East Asia. Species of Dryocora are known from New Zealand, Australia and Tasmania.
The Trombidiformes are a large, diverse order of mites.
Limnocharidae is a family of mites in the order Trombidiformes. There are at least 4 genera and about 12 described species in Limnocharidae.
Hydryphantidae is a family of mites in the order Trombidiformes. There are more than 30 genera and 130 described species in Hydryphantidae.
Archotermopsidae is a family of termites in the order Blattodea, known as dampwood termites, formerly included within the family Termopsidae. They constitute a small and rather primitive family with two extant genera and 5 living species. They may rarely infest structures but do not usually do so, nor do they cause extensive damage to buildings or other man-made structures unless said structure has been sufficiently damaged such as by water. As their name implies, they eat wood that is not dried out, perhaps even rotting, and are consequently of little use to humans.
Cocceupodidae is a family of mites in the order Trombidiformes. There are at least 3 genera and about 23 described species in Cocceupodidae.
Neotrombidiidae is a family of velvet mites and chiggers in the order Trombidiformes. There are at least four genera in Neotrombidiidae.
Tetranychoidea is a superfamily of mites in the order Trombidiformes. There are about 5 families and more than 2,200 described species in Tetranychoidea.
Hydryphantoidea is a superfamily of mites in the order Trombidiformes. There are about 6 families and more than 250 described species in Hydryphantoidea.
Thyasidae is a family of mites in the order Trombidiformes. There are about 7 genera and more than 30 described species in Thyasidae.
Psorergatidae is a family of parasitic mites in the order Trombidiformes.
Adamystidae is a family of mites in the order Trombidiformes. There are at least three genera, one of which is extinct, in Adamystidae. It is the sole family in the monotypic superfamily Adamystoidea.
Erythracaridae is a family of mites in the order Trombidiformes. There are seven genera accepted within Erythracaridae.
Johnstonianidae is a family of mites in the order Trombidiformes. There are about 7 genera and more than 20 described species in Johnstonianidae.
Pseudocheylidae is a family of mites in the order Trombidiformes. There are at least two genera in Pseudocheylidae.
Teneriffiidae is a family of mites in the order Trombidiformes. There are at least four genera in Teneriffiidae.
Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
Sejida is a suborder of mites in the order Mesostigmata. There are about 5 families and 13 described species in Sejida. The oldest known record of the group is an indeterminate deutonymph belonging to Sejidae from the mid Cretaceous (Albian-Cenomanian) aged Burmese amber of Myanmar.
