Mites are small arachnids.
The anatomy of spiders includes many characteristics shared with other arachnids. These characteristics include bodies divided into two tagmata, eight jointed legs, no wings or antennae, the presence of chelicerae and pedipalps, simple eyes, and an exoskeleton, which is periodically shed.
Erythraeidae is a family of mites belonging to the Trombidiformes. Larval forms of these mites are parasitic on various other arthropods, for example harvestmen, but the adults are free-living predators. These oval mites are rather large, usually reddish coloured and densely hairy. The legs, especially the first and fourth pairs, are long and adapted for running. They have either one or two pairs of eyes and can be distinguished from related families microscopically by the presence of a single claw on the tibia of the palp.
Erythraeus munsteri is a species of mite belonging to the family Erythraeidae. This is a large, oval red mite with a body length of up to 1.5 mm. It has two pairs of eyes and long, slender legs. This mite can easily be distinguished from closely related species by the extraordinarily long, blackish setae which cover the body and legs.
Balaustium is a genus of mites belonging to the family Erythraeidae. These are large red mites with one or two pairs of eyes set well back on the body.
The Prostigmata is a suborder of mites belonging to the order Trombidiformes, which contains the "sucking" members of the "true mites" (Acariformes).
Raoiella indica, commonly known as the red palm mite, is a species of mite belonging to the family Tenuipalpidae. A pest of several species of palm in the Middle East and South East Asia, it is now becoming established throughout the Caribbean. The invasion of this species is the biggest mite explosion ever observed in the Americas.

Paraulax queulensis is a species of gall wasp. Biology of Paraulax species is unknown but given they are associated with Nothofagus forests their biology is probably associated with the pteromalid gall community. This species is named after the place where it was first collected, Los Queules National Reserve. P. queulensis closely resembles P. perplexa, bearing common traits such as colour, habitus and several morphological characters. P. queulensis differs by having a more elongate body, which in the female is 4 times longer than it is high; its mesosoma is 1.6 times longer than high, while its metasoma is 1.9 times longer than high. The mesosoma is more dorsoventrally depressed. Its pronotum s 1.5 times longer laterally than high. It possesses longitudinal costulae running from the lateral margin of its pronotal plate to its lateral surface. Its scutellar foveae is discernible even when shallow. The antenna also differs: the pedicel of the female antenna is 1.4 times longer than wide.
Charletonia cuglierensis is a species of mite belonging to the family Erythraeidae, so named after its type locality. C. cuglierensis belongs to the group of species which possess two setae between coxae II and III. It differs from its cogenerate species by length measurements. It was first found in Sardinia, 6 kilometres (3.7 mi) south of Cuglieri.
Leptus pozzoicus is a species of mite. It is named after Porto Pozzo, near Santa Teresa Gallura, the place where the species was first collected. L. pozzoicus belongs to the group of species with two palpgenualae, and that have over four setae between coxalae II and III. It differs from its cogenerate species by various length measurements.
Charletonia austisensis is a species of mite belonging to the family Erythraeidae. C. austisensis belongs to the species group with two setae between coxae II and III. It differs from its cogenerate species by various length measurements. The species was first found in Austis, Sardinia, after which it is named.
Abrolophus mirabelae is a species of mite belonging to the family Erythraeidae. It belongs to the group of species that have comb-like setae.
Erythraeus berninensis is a species of mite belonging to the family Erythraeidae. It belongs to the group of species that has a basifemoral, setal formula 3-3-3.
Acroperus tupinamba is a species of crustaceans. Its name refers to the largest tribe of indigenous peoples inhabiting Brazil before European colonization. It was first found among decomposing leaves in Planaltina, Distrito Federal, Brazil. It is a small Acroperus, the length of the female at or below 0.6mm. Its body is egg-shaped, with its maximum height in its body's second quarter. Its dorsal margin is quite arched, with its posteroventral angle denticles being very small. It carries about 35 to 40 ventral setae, with its posterior setae being longer than in cogenerate species. Its head has a low keel, the distance between its eye and the margin of its keel being equal to its eye diameter, which measures 1.5–2 times more than the ocellus. The species' head, antennule and labrum is the same as for the genus. The postabdomen narrows distally, the length of which is about 3.2 its height. Setules near the base of its postabdominal claws are short. Its antenna comprises less than 1/5 of its body length. All of its apical setae are of the same thickness and length. A. tupinamba differs from the other known species of its genus: A. harpae and A. Angustatus, by its smaller size; long posterior setae of the valves; a shorter, wider postabdomen; short setules near the base of its postabdominal claw; and the characteristic morphology of its fourth exopodite's setae 5–6, which is similar to those of Nicsmirnovius.
