The Trombidiformes are a large, diverse order of mites.
In 1998, Trombidiformes was divided into the Sphaerolichida and the Prostigmata. [1] The group has few synapomorphies by which it can be defined, unlike the other major group of acariform mites, Sarcoptiformes. [1] Its members include medically important mites (such as Demodex , the chiggers, and scrub-itch mites) and many agriculturally important species, including the spider mites (Tetranychidae). [1] The superfamily Eriophyoidea, traditionally considered members of the Trombidiformes, have been found to be basal mites in genomic analyses, sister to the clade containing Sarcoptiformes and Trombidiformes. [2]
The 2004 classification retained the two suborders, comprising around 125 families and more than 22,000 described species. [3]
In the 2011 revised classification, the order now contains 151 families, 2235 genera and 25,821 species, and there were another 10 species with 24 species that present only as fossils. [4] These 151 families were classified into the same two major suborders [4] ：
e.g. Hydrachnidae
e.g. others:
Mites are small arachnids. Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari. However, most recent genetic analyses do not recover the two as each other's closest relative within Arachnida, rendering the group non-monophyletic. Most mites are tiny, less than 1 mm (0.04 in) in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others are predators or parasites. This last type includes the commercially destructive Varroa parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases.
The Acariformes, also known as the Actinotrichida, are the more diverse of the two superorders of mites. Over 32,000 described species are found in 351 families, with an estimated total of 440,000 to 929,000 species, including undescribed species.
Astigmatina is a clade of mites in the superorder Acariformes. Astigmata has been ranked as an order or suborder in the past, but was lowered to the unranked clade Astigmatina of the clade Desmonomatides in the order Sarcoptiformes. Astigmatina is now made up of the two groups Acaridia and Psoroptidia, which have been suborders of the order Astigmata in the past. Astigmatina contains about 10 superfamilies and 76 families under Acaridia and Psoroptidia.
Prostigmata is a suborder of mites belonging to the order Trombidiformes, which contains the "sucking" members of the "true mites" (Acariformes).
The Raphignathoidea is a superfamily of the Acari (mite) order Trombidiformes, comprising 1087 species in 62 genera and 12 families.
Endeostigmata is a suborder of acariform mites. There are about ten families in Endeostigmata. The grouping is strongly suspected to be paraphyletic, containing unrelated early diverging lineages of mites.
Parasitengona is a group of mites, variously ranked as a hyporder or a cohort, between the taxonomic ranks of order and family.
Stigmaeidae is a family of prostigmatan mites in the order Trombidiformes. At over 600 species, it is the largest family in superfamily Raphignathoidea. It has a worldwide distribution.
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.
Linopodes is a cosmopolitan genus of mites in the family Cocceupodidae. There are at least two described species.
Cocceupodidae is a family of mites in the order Trombidiformes. There are at least 3 genera and about 23 described species in Cocceupodidae.
Eupodoidea is a superfamily of mites in the order Trombidiformes. There are about 8 families and more than 160 described species in Eupodoidea.
Neotrombidiidae is a family of velvet mites and chiggers in the order Trombidiformes. There are at least four genera in Neotrombidiidae.
Trombidioidea is a superfamily of mites in the order Trombidiformes. There are about 8 families and at least 430 described species in Trombidioidea.
Tetranychoidea is a superfamily of mites in the order Trombidiformes. There are about 5 families and more than 2,200 described species in Tetranychoidea.
Penthaleus major, known generally as the winter grain mite or blue oat mite, is a species of earth mite in the family Penthaleidae.
Hydryphantoidea is a superfamily of mites in the order Trombidiformes. There are about 6 families and more than 250 described species in Hydryphantoidea.
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.
Anystoidea is a superfamily of mites in the order Trombidiformes.
