Glycyphagus is a genus of astigs in the family Glycyphagidae. [1] [2] [3] [4]
In adults of Glycyphagus, the prodorsum lacks external vertical setae ve. The internal vertical setae vi are long and barbed, and located posterior to the anterior margin of the propodosoma. The scapular setae si and se are arranged in a trapezoid or rectangle shape. In some species, there is a prodorsal sclerotization called a crista metopica. Some of the dorsal setae are long and heavily barbed. On the ventral side of the body, the subcapitulum has a distinct pattern of ventral ridges, and near the posterior margin of the body is the anus. The tibiae of the first two leg pairs have two ventral setae each. The tarsal claws are simple and small. Members of subgenus Lepidoglyphus have subtarsal scales on the legs. [4]
Females usually have a short external copulatory tube at the posterior end of the body. Males lack paranal suckers or tarsal suckers on the fourth leg pair. [4]
Mites in this genus live in a wide variety of habitats, including nests of animals (e.g. rodents, birds, bees), stored products, house dust, hay and grass. They feed on various organic materials. [4]
To disperse, Glycyphagus use insects such as bees (phoresis) or air currents. [4]
These species belong to the genus Glycyphagus:
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 again 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.
Varroa destructor, the Varroa mite is an external parasitic mite that attacks and feeds on the honey bees, and is one of the most severe honeybee pests in the world. These mites can infest Apis mellifera and Apis cerana, and the disease caused by the mites in the genus Varroa is called varroosis.
Varroa is a genus of parasitic mesostigmatan mites associated with honey bees, placed in its own family, Varroidae. The genus was named for Marcus Terentius Varro, a Roman scholar and beekeeper. The condition of a honeybee colony being infested with Varroa mites is called varroosis.
Varroa jacobsoni is a species of mite that parasitises Apis cerana. The more damaging Varroa destructor was previously included under the name V. jacobsoni, but the two species can be separated on the basis of the DNA sequence of the cytochrome oxidase I gene in the mitochondrial DNA.
Tarsonemus is a genus of trombidiform mites within the family Tarsonemidae.
Mesostigmata is an order of mites belonging to the Parasitiformes. They are by far the largest group of Parasitiformes, with over 8,000 species in 130 families. Mesostigmata includes parasitic as well as free-living and predatory forms. They can be recognized by the single pair of spiracles positioned laterally on the body.
The Raphignathoidea is a superfamily of the Acari (mite) order Trombidiformes, comprising 1087 species in 62 genera and 12 families.
Heteropoda davidbowie is a species of huntsman spider of the genus Heteropoda. It was described from the Cameron Highlands District in peninsular Malaysia and named in honour of singer David Bowie.
Histiostoma is a genus of mites in the family Histiostomatidae.
The Laelapidae are a family of mites in the order Mesostigmata. The family is also referred to in the literature as Laelaptidae, which may be the correct spelling.
Rhizoglyphus is a genus of mites in the family Acaridae. It has a worldwide distribution and is often associated with the bulbs, corms or tubers of plants.
The family Ameroseiidae is one of the three families of mites under the superfamily Ascoidea. There are about 12 genera and more than 130 described species in Ameroseiidae. The family has a worldwide distribution.
Parasitellus is a genus of mites in the family Parasitidae which are obligatory parasites of bumblebees. These mites can be found clinging to the carapace, sometimes in large numbers. Mites in this genus hibernate in the deutonymphal stage. In the tritonymph stage they can actively transfer from bumblebee to bumblebee from flowers, where they can survive up to 24 hours. After they arrive in a bumblebee nest, they will moult into adults. Whilst it is not known what factors trigger the mite to molt, in laboratory conditions P. fucorum were found to moult after eating fresh pollen, although overall moulting success was low. They are kleptoparasitic or neutral to beneficial, depending on life stage; females and deutonymphs feed on provisioned pollen, while other stages are predators of small arthropods.
This glossary describes the terms used in formal descriptions of spiders; where applicable these terms are used in describing other arachnids.
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.
Petrobia is a genus in Tetranychidae, containing 34 described species. It includes some pest species.
Roubikia is a genus of bee-associated mites occurring in the neotropics. They are mutualists or commensals, and feed on fatty acids from floral oils and most likely on fungi. The type species is Chaetodactylus panamensis.
Suidasia is a genus of mites in the family Suidasiidae and clade Astigmatina.
